Data Modeling Process.
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.
