Database access with the IBM Developer Kit for Java

With the IBM^® Developer Kit for Java™, your Java programs can access your database files in three ways.

• JDBC driver explains how the IBM Developer Kit for Java JDBC driver allows Java programs to access database files.
• SQLJ support explains how the IBM Developer Kit for Java allows you to use SQL statements that are embedded in your Java application.
• Java SQL routines explains how you can use Java stored procedures and Java user-defined functions to access Java programs.

• Access your iSeries database with the IBM Developer Kit for Java JDBC driver
  The IBM Developer Kit for Java JDBC driver, also known as the "native" driver, provides programmatic access to iSeries™ database files. Using the Java Database Connectivity (JDBC) API, applications written in the Java language can access JDBC database functions with embedded Structured Query Language (SQL), run SQL statements, retrieve results, and propagate changes back to the database. The JDBC API can also be used to interact with multiple data sources in a distributed, heterogeneous environment.
• Access databases using IBM Developer Kit for Java DB2 SQLJ support
  DB2^® Structured Query Language for Java (SQLJ) support is based on the SQLJ ANSI standard. The DB2^® SQLJ support is contained in the IBM Developer Kit for Java. DB2^® SQLJ support allows you to create, build, and run embedded SQL for Java applications.
• Java SQL routines
  Your iSeries™ server provides the ability to access Java programs from SQL statements and programs. This can be done using Java stored procedures and Java user-defined functions (UDFs). The iSeries™ server supports both the DB2^® and SQLJ conventions for calling Java stored procedures and Java UDFs. Both Java stored procedures and Java UDFs can use Java classes that are stored in JAR files. The iSeries™ server uses stored procedures defined by the SQLJ Part 1 standard to register JAR files with the database.
