The access of database systems can be divided into two types:

• EIS- tier databases: Database systems that are accessed via the Java DataBase Connectivity (JDBC) API.

• Non-EIS-tier databases: Database systems that are not accessed via the JDBC API. These databases are accessed via the vendor's proprietary protocols and APIs, the J2EE Connector Extensions, or CORBA.

Relational Database Management Systems (RDBMS) are typically used for enterprise data storage, and many providers use either JDBC 2.0 or 3.0 APIs. JDBC has two parts : a client-level API (to access the RDBMS) and a standard system-level contract for connection pooling and transaction implementation used by the vendors . The standard system-level API, in JDBC 3.0, is the same as the Connector architecture system contracts.
