Release 10.1A: OpenEdge Data Management:
DataServer for Microsoft SQL Server

Creating a schema holder

A schema holder contains a schema image of the MS SQL Server database that your DataServer application accesses. The schema image contains the schema for your data source—that is, its data definitions—in an OpenEdge format. Although OpenEdge applications can access a data source directly by sending SQL statements through the DataServer, they cannot directly access its data definitions and must use the schema-image information instead.
