The DataServer Tutorial : Modifying a schema image

Modifying a schema image

You can begin using the DataServer as soon as you load the Oracle data definitions into the schema holder. However, you might want to use certain OpenEdge features, such as labels, validation expressions, or validation messages. Or, you might want to change the default data type provided for fields in the schema-holder tables.
