Introduction

The Java Database Connectivity (JDBC) API provides universal data access from the Java programming language. Application developers can use the JDBC 3.0 API driver for RDM to write database applications and execute SQL statements.

The JDBC 3.0 API is comprised of two packages:

  1. the java.sql package
  2. the javax.sql package, which adds server-side capabilities

The RDM driver is a JDBC 4 Type V driver.

The RDM database management system uses the driver in one of the two following modes:

  1. Type 4 (pure Java) implementation with database connectivity to rdm-tfs. To use the RDM JDBC driver in this mode:
    • Add the driver (rdmjdbc-14.jar) to the classpath
    • Specify the host name (and optionally the rdm-tfs name) in the connection string: "jdbc:raima;rdm://hostname[:rdmtfsname]". For example, to connect to rdm-tfs running on localhost using port 21553, specify "jdbc:raima:rdm://localhost:21553".
  2. Type 2 (Native API driver) with embedded (local) rdm-tfs. Commonly referred to as RDM Direct Link configuration. To use the RDM JDBC driver in this mode:
    • Add the driver (rdmjdbc-14.jar) to the classpath
    • Make sure the RDM client libraries are in the path
    • Specify "local" as the host name in the connection string. You may not specify an rdm-tfs name. For example, "jdbc:raima:rdm://local".

For more information on the connection string for RDM JDBC, see RDMDriver.connect().
