The DataServer Tutorial : Modifying a schema holder

Modifying a schema holder

You can begin using the DataServer as soon as you load your data source data definitions into the schema holder. However, you might want to use OpenEdge features such as labels, validation expressions, or validation messages. You also might want to change the default data type provided for fields in the schema-image tables.
You can define OpenEdge information at the table and field levels in the schema holder. The following sections describe how to enter OpenEdge information at both levels. An additional section describes how to select an index to support the ROWID function.
