You can create Java classes that can be moved between levels of an enterprise application. The same Java class can be integrated into either the client application, a middle tier, or the database—wherever is most appropriate.

You can move a class containing business logic to any level of the enterprise system, including the database server, allowing you complete flexibility to make the most appropriate use of resources. It also enables enterprise customers to develop their applications using a single programming language in a multi-tier architecture with unparalleled flexibility.
