Technology

Rapid application development is used in development of software in which case a creation approach is applied. Short development cycle is involved in this process of data modeling. Limited time is used to obtain a functional system in applying this process. There are various processes which are involved in rapid application development. These phases include modeling of data, business modeling, process, generating the application and the resting phase. Data modeling involves determining the information to be analyzed. The generation of data includes determining the person involved in the generation  A functional information system is developed using rapid application development which involves team work.
   
In data modeling, group approach is used in rapid application development. A non existing information system is created in rapid application development. There are various activities and phases which are included in developing a new information system. These include requirements planning, user design, the construction phase and the cutover. During the requirement planning phase, business functions and the scope of the perceived business are obtained. The user design phase includes creation of models which enables user interaction. Prototypes are also formulated at this phase. Integration, coding and testing are effected during the construction stage. The information system may be changed to cover on the business functions.  Users are involved during the various phases. This reduces cost and development time. In rapid application developed an interactive system is obtained.
   
Rapid application development has various advantages and disadvantages. Cost reduction is achieved in creating systems using rapid application development. The involvement of users in every phase ensures reduction of costs. The rapid application development disadvantages include minimal time is required in developing quality systems, the business needs are not well presented. Highly specialized personnel are required to facilitate the completion of a system within the set time frame.
   
Software development makes use of the unified modeling language which makes use of various standards which were devised by the object oriented group. Visual models are created using the methods of graphical notation. The use of graphical notation enables the creation of rigorous systems.  Object oriented software are created using Unified Modeling language which involves modification, specifying, construction, visualization and documentation of the intensive system developed. The visualization is undertaken by considering various elements which includes activities, actors, components, and the statements which are used in the programming language. Unified Modified Language makes use of some techniques which are used in data modeling. This includes the modeling processes which involve object, business and component modeling.

The Unified Modified language is a programming language which various aspects from various techniques such as object modeling, Booch technique and the object oriented technique. This language can be considered as a standard language which can be used for modeling various systems such as distributed and coexisting systems. The Unified modeling language standards has been achieved as a result of various contributions of leaders within the information industry. There are various transformation languages which can be used to aid in transforming the Unified Modified Language.
   
Unified modeling language was devised with the support of several methods object oriented technique and the Booch method. There are various new techniques which have been devised based on the unified modeling language. This is because Unified Modeling Language has undergone some evolution. The various methods which have been devised from Unified Modeling Language include Dynamic Systems techniques and the abstraction technique. A system comprises of diagrams which should be differentiated from the Unified Modeling Language. A diagram can be considered to be a graphical representation which is shown in a system. The diagrams used in Unified Modeling language highlight some views of the system which may either be dynamic or static.
   
Prototypes are created during system development. Dynamic systems Development methods involves prototyping life cycle. Joint Application Design is involved in structuring of the prototypes in dynamic systems. There are various approaches which are involved in Joint Application Design. These include involvement of users in coming up with quality systems. Workshops are organized to bring together different ideas for modification of the system depending on the requirements of the business.

The workshops take on board both IT skilled personal and knowledge workers. To acquire the required information, top management people are involved in devising the system. A new information system may bring about difficulties and differences within the involved participate. This is handled by meeting consensus during the workshops. To eliminate any miscommunication in the new system, the workshop agenda is put forth clearly to ensure there is no misunderstanding between the involved parties. There are major steps which should be followed in having an appropriate Joint Application Development. The new information system attained appeals to the involved parties which include the users and the designers. This joint development of software eliminates miscommunication. The major participants in Joint Application Development include the documentation personnel, the sponsor amongst other participants. The workshops should be well stipulated with the limitations and objectives of the business being well highlighted.
   
There are some advantages and disadvantages in the use of Joint Application design. In the case of a large group, this technique is costly and awkward. The requirement modeling process includes the users. The new system may not face any differences since the users are involved in the designing stage. This technique is vulnerable to conflicts due to the various participants. This sets in the drawback of this technique in developing a new information system.
   
Functional Decomposition Diagram is a software development technique which makes use of the Agile techniques. In the development of software various methods such as agile are incorporated. The Functional Decomposition Diagram process includes blending of some of the well known techniques to enable the creation of a concrete process. The various practices included in the Functional Decomposition Diagram are devised from functional features. Functional software which is timed is attained through Functional Decomposition Technique. There are various basic activities which are involved in Functional Decomposition Diagram Process. The activities involved in developing software are well manned by the use of milestones. A concrete software model is achieved within the first three activities which are carried out.  Iteration occurs for the subsequent activities. The content and the coverage of the system are first highlighted to ensure a good system.

The overall model is attained through various alterations during the execution of the activities. The design process involves some inspection to ensure a functional system. The various practices involved in Functional Decomposition Diagram process include development by feature, Feature teams, Domain Object model. There are also inspection and subsequent which are done on the way to facilitate an efficient system.

Operating System
The Operating System used for this application is Windows 2008 Server. It is the most advanced and it is a high secured server operating system. Since it has the new significant features, it deducts the expenditure of running corporate networks, together with Network Access Protection, Server Core, PowerShell and Read Only Domain Controllers. Many accessible components, like IIS, Terminal Services and the file-sharing protocol have also had a detailed renovate.

DBMS used to manage the data
The DBMS used for this application is MS-Access. Microsoft Access offers the users with one of the trouble-free and flexible DBMS solutions in the present market. A plenty of wizards reduce the complication of administrative tasks. Microsofts minimum system requirements must be present in order to load MS-access in a system. The three of the main components of MS-Access that several database users will face - tables, reports, queries, forms, web integration and SQL Server integration.
The Tables permits creating the framework for storing information in a database. Apparently, a database that only stored information would be found useless until there are methods to retrieve information. To retrieve the information stored in a table, Microsoft Access permits to display the table and scroll through the records consists within it. Though, the actual power of a database contains in its capabilities to respond more complicated requests, or questions.The queries of Access give the ability to unite data from several tables and put specific conditions on the data retrieved.

Access also gives user-friendly forms of interface which permits users to provide information in a graphical format and contain that information transparently transfer to the database.The MS-Access is the suitable database mostly in the case of Desktop application. In the case of Microsoft Access we use internally developed applications.

User interface
The user interface is a device to interact users with the application. A user interface provides graphical icons and indicators, text boxes to give input and to get output from the application. It displays labels of typed commands or navigation text to completely represent the information and the actions accessible to user. The actions are generally executed by directly manipulating the graphical objects.Whats new for File Services in Windows Server 2008

The Storage is not a marginal expense anymore. The managing storage is not a simple volume and availability the organizations require maintaining their data more efficiently and more effectively. The companies decrease the price of storing, managing and maintaining data. By implementing policies of company and knowing the procedure to use storage, can administrators professionally use the storage and alleviate the risks of disclosing the data. The next boundary for administrators is to be able to maintain data based on value of business. The storage and share management gives a centralized location to maintain two significant server resources.

Volumes and folders which are shared on the network
The content of folders and volumes can be shared on the server over the network utilizing the Shared Folder Wizards Provision that is obtainable in management of Share and Storage. This wizard directs through the required steps to share a volume or a folder and allocate all appropriate properties to it. The provision storage on disks that is available on the server by Share and Storage Management, or on subsystem storage that support Virtual Disk Service (VDS). The Provision Storage Wizard directs through the process of generating a volume on an obtainable disk, or on a subsystem storage attached to the server. If the volume is to be created on a storage subsystem, the wizard will also directs through the procedure of generating a logical unit number (LUN) to host that volume. There is the option of only creating the LUN and utilizing the Disk Management to produce the volume later.

Buying and selling of cars has been a booming business in the market in todays society, people are tired of moving up and down the country in the yards to look for cars of their choice. Hence a car website (project) that will enhance the process of buying and selling at the comfort of your home or office or any other place will be the best thing that can ever happen to the citizens.

First, sellers are supposed to post photographs of their cars with different dimensions (front, back, right and left side, engine and interior) with full details of the car e.g. car make, car model, transmission, displacement, price, year of registration, interior and exterior color, type of fuel, mirage as this will enable the buyers to view the car comfortably and make wise decisions before getting into the transaction. 

Buyers will not need to make blind payments as they will be dealing with the car owners direct for negotiations since their full contacts (phone numbers and email addresses) are already displayed adjacent to the car, this means there will be no cases of fraud. Once cars have been posted, they will not be published (visible to the buyers) until payment is done, hence there is the admin section for publishing cars and only the website administrator (owner of the business) has the website pass codes.

It will be necessary to have the knowledge of information technology this means the buyers and sellers must be able to use computers and internet, use of digital cameras will also be important because of uploading photographs in the system, anyone willing to own a car will be able to access this website but documents of ownership like log books, identity cards or passports must be presented to avoid cases of theft and fraud as well. The home page will have a number of selected photos (say ten) with the vehicles which will have the flashing feature, the images will be on for 10 seconds each and on and on and on, this means different cars will be displayed systematically, but there will also be a link of sell a car where all cars are to be found.

1. The purpose of integrating technology into the lessons you saw -- what were some of the benefits
    The purpose of integrating technology into the lessons is basically to help the students develop their potentials and maximize their capacities to learn more and excel in school. Generally, technology integration motivates the students to go to school and learn the lessons well because of this new interesting approach in the learning method. Some of its benefits are largely seen in those students with disabilities since it enables them to easily cope up to the lessons. Primarily, through the aid of modern technology into their learning process, they function and live like any normal student do. Another benefit of technology integration is that it is enjoyable to do. Hence, a lot of students are taking interest in it. According to once professor in the video, this approach not just decreases the number of drop-outs in schools but it also enhances the students to learn something fun and different.

2. The computer experience you have had that might be similar to what you saw.
    In my own experience, a teacher in one of my subjects assigned us to report in class the history of our school. My group mates and I made of use Powerpoint presentation to narrate the schools history. We also utilized pictures and video clips to make the report interesting. At the end of the day, we made our teachers and our classmates impressed of our output.

3. The aspects of the technology integration that interested you most -- what might you like to be able to do as a teacher
    Personally, the aspect of technology integration that interests me most is the aspect where the elementary teacher in Tolenas Elementary School let her young students to explore and document their town using camcorders and computers. For me, it is best to teach children to participate in school at a young age and I found it effective since her students indeed took the project seriously by dedicating their time and effort. As a teacher, what I would like to do is to motivate my students to learn by making the subject appealing and interesting to them. There are actually a lot of ways to do that and one of them is to incorporate in the learning method the use of modern technology.

1.What was the purpose of integrating technology into the lessons
    The ultimate purpose of integrating technology into the lessons is to develop the learning method done in schools in order to maximize the potentials of the students. It enhances the students to become creative and participative since learning process now becomes interesting. At a young age, students were already trained to use modern gadgets because it encourages better learning. Technology is of great help as well, especially to those students with disabilities in coping up to the lessons and live like normal students.
2. How did the videos change how you think of using technology with students
    The videos made us understand that integration of technology is crucial not just in the process of learning but on making the students understand the society as a whole. It also portrays that technology, if used with proper guidance (e.g. teacher or instructor), can indeed help the students in maximizing their potentials.

Write an example from your own experience of the successful and meaningful integration of technology for learning purposes. What made the experience successful Meaningful
Based from my own experience, our school has made use of computers as a medium for the students to better understand the lesson. In reporting, we use PowerPoint presentations and video presentations. This way, students get to know the subject really well since there are now certain guides to the learning process aside from the normal lecture done by teachers. What made it more meaningful is not just the fact that our grades increased but more importantly, what we still do remember the lessons and incorporate them to our everyday lives.

Technology has come along way in assisting people with special needs. There are various kinds of people with special needs, these people just like any other need to live and do things the normal way. For example those who cannot walk need to have some form of mobility in one way or another, those who cannot talk need to communicate in one way or another, those who are deaf need to hear in a way and many other examples.
These paper looks at the various disorders and the way technology is made to assist. Here we look at five most special needs areas that we can tackle. We also look at the kind of technology used to assist the needs in each area.
First these are the special needs areas that the paper is going to analyze
Autism
Hearing
Sight
Mobility
Amyotrophic lateral sclerosis (ALS) (Lou Gehrigs Disease)
Autism
This is a disorder of some kind of neural development that has some attributes related to impaired social interaction and communication.
It is a disorder that takes place early in a Childs life, in North-America it is one of the fastest growing disabilities.
This kinds children with this disorder tend to fixate a times. Some do things for a very long time like gazing TV for a long time or coloring for a long time. There is no medical cure for this kind of disorder but, through technology autistic children are able to communicate using virtual peers.
Virtual Peers
Virtual peers are computer animated and enhanced children capable of carrying on realistic conversations. All these are carried out by researchers who would have autistic children shown virtual peers and then invite them to play together. The main communication between the two is a video game control interface.
Hearing
Hearing is one of the most important senses in all the sense there are. When one is incapable of hearing then he or she will not be able to communicate properly. There are two great technologies that can assist those with that kind of a disorder.
Personal Communications Software
The PSC is a system that actually puts together audio communication and hearing support that is used for the elderly and even the hearing impaired through a Personal Hearing System. The whole system uses the Wireless Body Area Network (WBAN).
This system has a perspective of giving the impaired a solution to enhance hearing.
Basically the Personal Communications System is a hand held device it has what is called concentrator information that helps in the facilitation of personal communication.



Cochlear implant
This complex electronic equipment that is small in size and assists in the provision of sound to those who are profoundly deaf, it consists of a microphone, a speech processor, a transmitter and receiver and an electrode array.
Its used to assist hearing and not to restore normal hearing. It normally gives a deaf person a representation of sounds in the area and also assists to understand speech.
Sight
This is a disorder that renders a person not able to see. There are several technologies put in place to assist this disorder.
Artificial retina implant

This is a small electrical implant that is attached to the retina. When used it may one day restore some sight.
This artificial retina is made to take the place of photoreceptor cells inside the brain that have the function of capturing and processing light.
Computer-assisted vision technology
This is the use of electronics and software to make images seen well. There is the technology of e-sight, it looks like a pair of sunglasses which has an added electronic device that is clipped to a belt of the user. The glasses have built in special camera and image processing software in the belt mounted part-that manipulates the cameras image in different ways to assist those with vision impairment to have a clear vision.  
Mobility
The disorder of mobility renders one incapable of moving around. The following are technologies that assist one to move around.
Standing wheelchair
This is simply a normal wheel-chair that assists people who are not able to walk. The only difference is that this wheel chair is able to move up to a considerable height making one think that it is standing. There are various types of this technology. There are some that can balance and climb stairs, and still some can support one on hisher legs and move around.
Artificial limb
This is a type of prosthesis that replaces some missing part of a body like a leg or an arm. The actual type of limb used is usually determined by the extent of loss and place of the missing part.
Artificial limbs are used for many reasons
Disease
Congenital defects
Accidents
Congenital defect create the need of having an artificial limb when one is born with a damaged or even missing part.
Emerging technologies related to this include Robotic limbs and Direct bone attachment.
Amyotrophic Lateral Sclerosis (ALS)
This is an auto neuron disorder that causes degeneration in the whole of the brain and even the spinal chord. It makes one be weak and robs himher of the ability to communicate.
Speech technology
 There is Voice for Joanie, it is operated using a computer screen. It creates and provides the gift of speech to those suffering from the disorder. It has been in existence for a long period of time.
This kind of system offers technical assistance and voice communicators for as long one needs when the person using it passes on then it is donated to another one with a similar complication.
Speech therapy and Assistive Devices
Since ALS mostly affects the muscles used to speak, one suffering from the problem can employ a speech therapist, who can teach the patient how to better understood. As it progresses they may learn how to use speech synthesizers and computers to communicate.
These devices can also help the patient to maintain mobility.
Conclusion
In a nut shell, the people who have special need like autism, hearing disorder, sight disorder, ALS, and mobility problems are well taken of by technology.  The various kinds of technology that are in place for these disorders are virtual pals, personal communications software, cochlear implant, artificial retina implant, computer assistance vision technology, standing wheelchair, artificial limb, and speech therapy. All these are some of the technologies put in place to help the people with special needs. There are researches that are in place to seek improvement in some technological aids so as to make the lives of the impaired much better.

There have been various discussions regarding spreadsheets and databases. This could be attributed to the fact that a lot of people contest the feasibility of one tool over the other. In this paper we will provide a definition of what a spreadsheet is, then derive the definition of a database and provide a comparative discussion between the two.
Spreadsheet applications, otherwise known simply as spreadsheets, are computer programs which allow for users to simulate the creation and manipulation of spreadsheets electronically. They can easily be described graphically as applications which display cells altogether forming a grid of columns and rows. Cells may contain alphanumeric texts or numerical values, and they can also contain formulas to describe cell relationships. Most spreadsheet applications have support for multi dimensional linkage, meaning two or more spreadsheets may be linked with each other using formulas.  Once the formulas required have been defined, the user may then experiment on the values to see effective changes and behavior. This characteristic of spreadsheets allows them to be considered as basic decision support system. Spreadsheet applications are widely used in homes, offices and business establishments. In cases of small businesses, the functionalities provided by spreadsheets prove to be enough to maintain daily operations. However, when businesses get bigger, more data is inputted and manipulated by more users, the need for better solutions becomes apparent. This is where database gets into the scene. A database is a computer program which offers mechanism for storing, manipulating and retrieving information in an organized manner. Like spreadsheets, databases approach this functionality by using tables. Database tables also consist of rows and columns, the data type that can be stored in cells under the same column is set by the user, and this characteristic of the column is called its attribute. A row or an entry in a database is called a record. At this point, it would seem obvious that databases share a lot of similarities with spreadsheets, if so, what exactly are the characteristics of a database that makes people consider using them instead of spreadsheets The answer is that databases are actually far more superior to spreadsheets in terms of the ways users are able to manipulate data. Databases are easier to share unlike spreadsheets multiple users may gain access to a single database simultaneously. They offer better security and data integrity because the data type in each column is defined and as a result, users are protected from committing simple mistakes. Databases have greater capacity, entries in a database may reach billions, and even with this staggering amount of data the user does not have to feel overwhelmed, since databases can be queried according to the needs of the user. Databases create less duplication both file duplication and duplication of source data.  Databases however, are more complex to understand than spreadsheets because of this it requires more investment in training but is sure to yield more profit. To wrap it all up, the differences that exist between these tools are mainly attributed to the level of complexity of the work being done and the user is willing to take.

1) Several evidences point out that climate change is caused by human activities. Among these evidences are the speedy increase of carbon dioxide concentration in the earths atmosphere for the past decades consumption of more than half of surface fresh water elevated fixation of atmospheric nitrogen extinction of various flora and fauna species and, utilization of majority of the land and its resources (L2).  These events link to human activities and the occurrence of climate change has been intensively researched in the past years after humanity was struck with the drastic effects of climate changes like typhoons, El Nino, La Nina and low harvest.
The speedy elevation of carbon dioxide (CO2) atmospheric concentration has been well documented and monitored. Since 1957, a significant increase in CO2 atmospheric concentration from 315 ppm to 362 pmm has been observed. The continuous elevation of (CO2) is due to various human activities especially the employment of fossil fuels. Every year more than 5 billion metric tons of (CO2) is emitted into the atmosphere (Vitousek et al., 1997). Human activities have greatly increased the atmospheric carbon dioxide concentration which led to global warming and the consequent climate change.
The exploitation of majority of the land and its resources also has a big impact to the climate change phenomenon. Various human activities related to agriculture like land clearing, grazing intensification, forestry and animal domestication contributed negative effects to the earths ecosystem. Humans built diverse infrastructures like dams, irrigation systems, flood protection structures, buildings, roads and bridges which plastered the earth with asphalt and concrete (Kareiva et al., 2007). The employment of vast amounts asphalt and concrete did not only contribute negative impacts to the ecosystem but also helped retain more heat within the earths atmosphere. Without the intensive stresses in the earths resources inflicted by human beings, climate change could have occurred in its normal pace and its drastic effects would have been non-existent. It is already undeniable that change is indeed a result of human activities.
2)    The most pressing consequences of climate change are food supply depletion, low availability of water, extinction of animal and plant species, increase in the occurrence of natural disasters and emergence of various diseases (L13, L14, L15, L20).  At present, the terrestrial and marine ecosystem has been widely affected by the elevation of temperature. There has been continuous depletion of terrestrial and marine flora and fauna (L13). The reduction in the number of species and population of animals and plants are very significant to the survival of humans. Continuous consumption along with the effects of climate change for example has caused lowered harvest of crops, plants and marine food (L17, L18). In addition to this the food supply is also threatened by the occurrence of different global disasters like typhoon, landslides and flood which affected the agricultural production and cost numerous lives. These consequences of climate change are not minor because in just this decade the loss in food, infrastructure, livelihood and human lives has been gigantic.
3)    The most significant response to climate change is the reduction of greenhouse gases emission thru human lifestyle modifications. These adjustments include the utilization of alternative energy sources like biofuels, solar power and wind power instead of burning fossil fuels (L25).  The huge amount of CO2 generated from fossil fuel burning in power plants, industries and even cars can be considerably lowered with the use of biofuels. Aside from that this energy source is renewable and can contribute to the waste reduction process.

The all-electric car is a vehicle that only runs on electric power. An all-electric vehicle is different from a hybrid in the sense that a hybrid has the option of multiple fuels, usually electric and petrol, but these days hydrogen is becoming an electric fuel as well. The stored chemical energy in the batter is used to turn individual turbines at each wheel to propel the car. Therefore, it has no internal combustion. The Mercedes-Benz research centre at Stuttgart has revealed information regarding Daimler AG developing an all-electric version of Mercies luxury sedan, The S-Class that runs on lithium ion batteries. The battery will have two options for charging the first is a direct plug-in method in to a wall socket, like most conventional electric car and appliances. The second is through a dynamo like device fitted within the car that charges the battery through kinetic energy while the car is driving. The dynamo is similar to a turbine and will convert the kinetic energy in to stored chemical energy in the battery. However, the dynamo cannot fully charge the battery as the power generated will be consumed simultaneously. On one full charge, the battery can drive the car up to 170 kilometers or 105 miles.  There has also been news that in 2011, Mercedes will produce an all electric version of its new high performance luxury supercar, the SLS AMG. The SLS will use similar technology to the lithium-ion battery.  (Mercedes-Benz developing 100 electric car, 2008)
Pros
All-electric cars have an advantage that they are less complex to build and manage than hybrid cars. They have simpler mechanisms similar to laptop computers. In fact, the all-electric sports car, the Tesla Roadster runs on over a 100 laptop computer batteries.
The advantages of this technology includes the fact that it is environment friendly a regular S-class has a 6.0 liter V12 engine that consumes high-octane petrol and gives an average mileage of 16-18 miles per gallon. The electric powered vehicle will give 105 miles on a single charge. The luxury sedan will be affordable to run.
The car will also have zero carbon emissions, compared to petrol powered cars and are completely environment friendly. Performance will be similar to its petrol-powered counterpart.  (Mercedes-Benz developing 100 electric car, 2008)
Cons
Some disadvantages include the time for fully charging the cars battery. A petrol-powered S-class tank would fill up in a matter of minutes, while the lithium battery of the new S-class takes about six hours.
Another disadvantage is that there are still not enough charging stations along highways and motorways, so if a car runs out of power, it will have to be plugged in to a household or commercial wall socket, causing a lot of inconvenience.
Electric power cars are much more expensive than normal petrol powered cars. Recently, hybrid cars have become more affordable but all-electric cars are much expensive. The price of the S-Class, which is expected to be much higher than the petrol powered version. Mercedes states that the price of the vehicle depends on the option of whether the lithium-ion batteries will be purchased by the customer or leased.  (Mercedes-Benz developing 100 electric car, 2008)
