Middleware is a successful technology in the business environment that allows companies to introduce flexibility into their business models and integrate multiple systems. This technology solves problems of communication between legacy applications and new applications by transforming data into a standard format. The purpose of this project is to research and develop a middleware solution for the Clustered Environmental Data ARchive (CEDAR). CEDAR is operating not in a business environment but a science-based environment and runs large amounts of queries on extremely large data sources. Integrating it with a middleware component will allow extensibility of the current system. It will allow multiple data sources to be queried at once and allow transaction processing across distributed applications all because of a built-in rules engine that directs data and notifications based on states.
