ABSTRACT
Components lie at the very heart of the future vision of computing. Corporations expect that they soon will be running their businesses using Webenabled, enterprise business applications composed of predefined, replaceable components that are distributed over networks. Although part of the application may run on a client, part on the middle tier, and another part on a back-end database server, its comprising components, written in different languages and supplied from multiple sources, will be able to work together to perform the application’s services.
