A JDBC driver is a software component enabling a Java application to interact with a database. JDBC drivers are analogous to ODBC drivers, ADO.NET data providers, and OLE DB providers. To connect with individual databases, JDBC (the Java Database Connectivity API) requires drivers for each database. The JDBC driver gives out the connection to the database and implements the protocol for transferring the query and result between client and database. JDBC technology drivers fit into one of four categories. 1. * JDBC-ODBC bridge 2. * Native-API driver 3. * Network-Protocol driver (Middleware driver) 4. * Database-Protocol driver (Pure Java driver) or thin driver.
