Software
Structured approach- follows the software development cycle. It follows the whole program and then divides it into steps that can be systematically followed to conclude to a solution. Each step must be completed before the next step is about to start as correcting each step is vital. The steps which take place in the structured approach are:The Structured approach is mostly used for complex programs. The advantages of this implementation are it is thoroughly testing, it meets the requirements of users and uses a range of experts. However the disadvantages are it is costly, time consuming and it requires a wide range of different skills.Prototyping approach- involves building
The advantages of EUD should meet exact user requirements and it is quick and cheap. Prototyping would be used in the manufacturing and engineering to produce an early version of a product. Evolutionary prototypes become the full working program. The disadvantages are it may not meet exact program requirements and it may involve copyright and intellectual property rights of others. a working model that is evaluated by users. Rapid applications approach- or RAD is ant method of software design that uses tools to quickly generate a program for a user. There are 2 types of prototypes used: information gathering and evolutionary. End user approach- is where the user adapts existing software tools to suit their needs or to obtain a solution to a problem. The advantages of RAD are fast development, it is relatively cheap and can reuse code. For my project I have selected to use the RAD Approach as I have had a previous experience with a CASE Tool which I have used on various tasks and which is a RAD programming application which is Visual Basic 6. The advantages of the prototyping approach would be it is relatively fast development, and it models a larger project which allows easier modification for the end product. 0 it is therefore apart of a CASE Tool be included in the RAD approach. Disadvantages would be that it may be difficult to implement it as a full working program. The end user approach wouldn't be of any of use as it is mainly used for solving personal problems and it would be relevant to what I am trying to achieve.
