The Enterprise Data Bus (EDB) lives within the Enterprise Data Pump (EDP). The pump is responsible for directing traffic and translating between data "understandings" at different points in the networked system.

You can almost view the pump as a network layer above the bus.

More then just a bus, the pump can cause dynamic translations between metadata and actual data. It can sense when a database has changed and then automatically issue new commands to update data in-memory or in a database. It can trigger events and automatically handle all of the database connections.

The bus acts as a virtual community consisting of applications, databases, external and internal clients. Each of the community members see the data landscape as a single context sensitive virtual database.

The bus can very efficiently transport just pure data (without the need for any form of meta descriptions), events and exceptions between the various members of the application community.
