Why to go Business Class (IT applications)

Business applications still represent the largest installed software base of the information technology market. The authors identify business applications as those information systems which are, in general, characterized by a relative low level of algorithmic complexity, a large amount of persistent data needing concurrent access, the need for online access within a given delay, and a high degree of security. They present the Business Class project, which foresees a generic object-oriented (OO) model for analysis, several technology related OO models for design, an integrated CASE tool environment to support both phases, and an accompanying methodology, all dedicated to the domain of business applications. The possible benefits of the use of OO technology for business application development are discussed. The solution proposed by the Business Class project is introduced. The generic OO model used for the analysis phase is described.<>
