Use

In this section you will learn how to work with Open SQL/JDBC and Open SQL/SQLJ in the SAP NetWeaver environment. The simple example demonstrates how you can store data in database tables and use a simple Web interface to insert data into the tables and to retrieve data using queries. The Web application accesses two tables in which data about the employees and the departments in a company is stored.
