Release 10.1A: OpenEdge Data Management:
DataServer for ODBC

> ## Maintaining a schema holder

> The Data Administration tools provide a set of DataServer utilities that you can use to maintain a schema holder. Chapter 5, "The DataServer Tutorial," describes these utilities. Recall that you must have select privileges on certain data-source objects to update a schema holder; see the "Establishing permissions" section for details.

> If you make changes to an ODBC data source, make sure to update the associated schema holder to reflect those changes if you want them to be accessible to a DataServer application. Note that you do not need to update the schema holder if the application will never access data objects affected by the change. For example, if you add a table object that a DataServer application will never access, you do not need to update the schema holder.

> Each time that you update the schema holder, you must recompile your DataServer application (`.p` and `.w` files) to generate new r-code.
