For the analysis and the design of the system the different tools and technologies available in the S/W engineering field have been applied are:-

  • Top-down approach and also the bottom-up approach have applied for gathering, analysis, designing and testing etc.
  • Decision table, decision tree have been also designed and used for the analysis and designing of complex queries.
  • The logical tool algorithm, flow chart, structure English etc have also been used in some cases to solve the problem of calculating items.
  • Waterfall model concepts have also been used for the implementation.
  • In the testing phase user acceptance test, string test and the program test have been performed.

So the improvements of the proposed system S/W engineering paradigm have been applied.
