JDBC provides a standard interface for accessing a relational database from a Java application regardless of where the application is running and where the database is.From an Oracle 8i perspective it provides a way for Java applications to call SQL and PL/SQL.This chapter explains the use of Java Database Connectivity for database access in Java.It highlights the method to incorporate Java in the Oracle 8i database using JDBC.Applications can use these features in exactly the same way as with earlier versions of JDBC.All four Oracle JDBC drivers support these changes.The various methods of using JDBC starting from the querying and returning of resultsets to executing DML from the Oracle 8i database are described in detail. A case study is presented to illustrate the concepts.

Oracle JDBC extensions are also discussed, and a case study is presented to illustrate the concepts.

The following gives a detailed description of each of these drivers: This driver is a Type 4 (Proprietary Protocol-Net) driver and is written in 100% pure Java making it platform independent. It implements the TCP/IP protocol that emulates Oracle's Net8 and TTC (the wire protocol of OCI) on top of Java sockets. Figure 3.2 A configuration of an Oracle client-side JDBC thin driver.

Java applets are good candidates that make use of this driver. This is a native-API Type 2 driver that is suited for client-server Java applications.

In other words it is a way to execute SQL statements and also call stored database procedures.

One important feature of JDBC is location independence.

There are four types of drivers defined by JDBC as follows: Oracle 8i provides four types of JDBC drivers, namely, thin drivers, OCI drivers, server-side thin drivers, and server-side internal drivers.
