Most applications use a database to store and manage data. To develop an application running on the SAP MaxDB database, you can choose between several programming interfaces. Some of these interfaces can also be used to access DBM Server and Loader functions.

You can also use a SAP MaxDB database as the database for your SAP system, for example as SAP Business All-in-One. Using SAP MaxDB databases in SAP systems is standardized and is not described in this section.

Prerequisites

You have created a database.

More information: Creating Databases

Procedure

  1. Develop the SQL statements that your application uses to access the database.

    Recommendation Recommendation

    • Acquaint yourself with the general recommendations for developing database applications.

    • Formulate your search conditions to be as selective as possible.

      More information: Analyzing Database Performance, SAP Note 819641

    • Use prepared statements. Prepared statements have the following advantages:

      • They achieve better performance when the same prepared statement is executed again.

      • No SQL Injection is possible.

      More information:

    End of the recommendation.

  2. Connect the application to the database via an interface.

    Recommendation Recommendation

    For Java applications:

    • Use the JDBC connection management provided by the container.

    • During deployment, install the SAP MaxDB JDBC driver in the container rather than in the database application.

    End of the recommendation.

  3. Test your application.

    The Messages manual explains database error and information messages and recommends how you can react to them. The messages are sorted by error number.
