The JDBC API is part of the Java 2 Platform, Standard Edition and is not specific to . It consists of the java.sql and javax.sql packages, which is a set of classes and interfaces that make it possible to access databases (from a number of different vendors, not just ) from a Java application.

To develop applications successfully, you will need to learn JDBC. This section does not teach you how to program with the JDBC API.

This section covers the details of application programming that are specific to applications. For example, all JDBC applications typically start their DBMS's JDBC driver and use a connection URL to connect to a database. This chapter gives you the details of how to start 's JDBC driver and how to work with 's connection URL to accomplish various tasks. It also covers essential concepts such as the system.

application developers will need to learn SQL. SQL is the standard query language used with relational databases and is not tied to a particular programming language. No matter how a particular RDBMS has been implemented, the user can design databases and insert, modify, and retrieve data using the standard SQL statements and well-defined data types. SQL-92 is the version of SQL standardized by ANSI and ISO in 1992; supports entry-level SQL-92 as well as some higher-level features. Entry-level SQL-92 is a subset of full SQL-92 specified by ANSI and ISO that is supported by nearly all major DBMSs today. This chapter does not teach you SQL. You will find reference information about the particulars of 's implementation of SQL in the .
