Specialized case tools for the development of information-calculating applications

Abstract

© SGEM2017. All Rights Reserved. This report presents an approach to building specialized computer-aided software engineering(CASE) tools for the development of information-calculating applications including computer aided accounting, business correspondence, statistics etc. These tools form an integrated development environment allowing the computer aided development of different applications in this field. The concept of the integrated development environment is defined as aset of tools and techniques allowing the design and development of software applications. This concept, previously used in procedural programming, has more recently proved to be a very important attribute for object-oriented programming. Integrated development environments traditionally include tools for the design and implementation of software systems, different libraries of classes, programming tools and program generators. Theintegrated environment which we consider in our report consists of a formulainterpreter, a screen form generator and a specialized library of classes. The distinguishing features of information-calculating applicationsare the processing of a set of tables and the making calculations which can be conveniently represented by thetools of relational database systems. The implementation of software productwas carried out using the Visual FoxPro database system and has been practically tested in a series of commercial applications concerning computer aided accountancy and business correspondence.
