Study On The Stability Of Business Activity Based On Domain Business Model

Under the upsurge of information construction of enterprise, technology of rapidly building information system is needed, CBD comes forth under such a trend. But so far, component's reuse performance isn't very well, and the advantages of CBD don't show up. The main reason is that model and method used for designing business component isn't perfect.Nowadays, most researches focus on the technology aspect of component realization, but such researches is based on the assumption that model of domain business component already exists. So, researches on business process and business activities which consist the business process, from management perspective and business analysis, is inadequate. Domain knowledge that can apply to the whole domain isn't abstracted. These lead to lacking of reuse business components. Due to the feature of business activity, such as atomic, stability, commonality and assembly, we encapsulate a business activity as a business activity component and assemble business activity components viewed as the basic element of component model to build a whole application system.Firstly, this thesis explains the basic concept of CDB, then introduces domain analyse and domain model which result from domain analyse. After that, it builds a domain business model based on business activities and gives models of order-processing business activity which come from two enterprises. These two enterprises adopt different produce manners but both in the same manufacturing way.Secondly, this thesis analyzes business activity and its features in detail, puts forward the feature parameters that describe business activity , then discusses the stability of business activity and its rules from the horizontal and vertical aspects.Lastly, this thesis builds a mathematics model for computing resemblance of business activities and gives a instance of computing resemblance.
