Chapter 7: The DataServer Tutorial • Adding extended ABL support 250 OpenEdge Data Management: DataServer for Microsoft SQL Server
Demonstration databases for DataServer for MS SQL Server Demonstration databases for DataServer for MS SQL Server The demonstration databases for the DataServer for MS SQL Server allow you to run the tutorials from this chapter, code examples, or your own procedures. The demonstration databases are not part of the OpenEdge installation media. To create and initialize a demonstration data source, you run the OpenEdge DB to MS SQL Server utility, which migrates the sports database to your data source and then creates a schema holder. (See the “Preparing to create demonstration databases” section on page 252 for detailed instructions.). After you do this, you are ready to run the tutorial exercises or your own applications against the data source. Before you create a demonstration database, be sure that your system meets the following prerequisites: • Sufficient privileges to create a database, add users, and create tables • Sufficient disk space for your database OpenEdge Data Management: DataServer for Microsoft SQL Server 251
