Release 10.1A: OpenEdge Data Management:
SQL Development

JDBC architecture

OpenEdge uses a Type 4 JDBC driver.

Figure 2–1 shows the architecture of a Java application using a Type 4 JDBC driver.

Figure 2–1: OpenEdge JDBC Type 4 driver architecture

In Figure 2–1, the Java application includes calls to the JDBC API. A JDBC API call must be performed using either the DriverManager.getConnection or the DataSource.getConnection method. The getConnection method obtains a connection to the appropriate JDBC Driver. The DriverManager or DataSource class is used to manage that connection.
