A Business Process Driven Multidatabase Integration Methodology

Development of multidatabase systems requires a careful understanding of the data requirements and of the data interaction between the participant sites. Total integration of the data is not feasable, due to such reasons as the dynamics of today's information requirements. We therefore put forward that a multidatabase system must be built on a partial integration. In this paper we outline a methodology that draws on business re-engineering principles to guide the developer through the process of creating partially integrated schemata. This methodology also gives us added beneets by specifying integration requirements and cost factors, and thus limiting/weighting the options given to the developer during the integration process.
