Events Propagation From The Business System Level Into The Information System Level

Active database systems (ADBS) have been developed for applications needing an automatic reaction in response to certain event occurring. The desired behaviour is expressed by event-condition-action rules (ECA rules), which have been proposed by HiPAC as a formalism for active database capabilities. A set of rules, implemented in active database management systems (ADBMS), is taken from the particular application domain. However, in the application domain or ontology, to which the rules belong, they are not always expressed in terms of ECA rules. This chapter covers how events, as an important part of ECA rules, are modelling in the process of rule-based systems development. Section I describes the main problem, which is going to be analysed in this chapter. Section 2 reviews related works on events modelling in the process of systems development. Section 3 details events propagation from the business system level into the information system (IS) level. Section 4 presents a case Study and Section 5 concludes the paper.
