Introduction 1–20
Initial Programming Considerations 2 An application developed in the OpenEdge Studio can use the DataServer for MS SQL Server to access data from multiple sources transparently. With the DataServer, your applications can access information in both OpenEdge databases and MS SQL Server databases. This chapter discusses fundamental considerations you need to know to plan your applications and design your databases. For example, you need to know the differences between OpenEdge databases and MS SQL Server databases, as well as the DataServer strategies for resolving these differences, which your application might need to accommodate. Specifically, it discusses the topics in the following sections: • Database design issues • Data types • Record creation • Data source record locking • Transactions • Error handling • Cursors • ABL issues • RDBMS stored procedures
