Abstract

Large-scale, loosely coupled systems architectures are emerging as a natural pattern for wide-area information sharing. We’re also seeing database systems increasingly interacting with messaging technologies such as message-oriented-middleware. Integrating pub/sub functionality into the database system represents a promising approach to cross-enterprise data sharing. On one hand, database systems already provide many features that a messaging-based architecture can exploit, such as reliable storage, transactions, and triggers. On the other hand, integrated pub/sub capabilities in the database account for information-sharing systems that are simpler to deploy and maintain. However, pub/sub and database technology have evolved independently, so designing and implementing database-pub/sub aware systems requires bringing together concepts and functionality from two separate worlds. In this talk I will discuss some of the research issues involved and describe an early prototype.
