SQL/JDBC for Reality

SQL/JDBC for Reality consists of a package of Java classes. These classes can be instantiated by a Java application, applet or servlet and their methods can be called to connect to a Reality database, send requests to the Reality SQL server and receive the results.

The diagram below illustrates the Reality SQL/JDBC client/server communications path.

Reality SQL/JDBC client/server communications path

The JDBC driver is a Type-4 driver — this means that it communicates directly with the server using a native protocol and is written entirely in Java. The driver uses the client's networking software to communicate with the Reality server process using DDA messages. Applications, applets and servlets issue SQL statements by making calls to the JDBC standard API.
