Description
schema
String
The type of schema that will be used. Valid values are "Auto", "Profiles", and "Marketing":
In an Auto schema, the system automatically detects the presence of the new Marketing System expressions table, named "mktg_expression", in the Marketing System (Campaigns) database. If this table is in the database, the Expressions system initializes in Marketing System mode. If this table is not in the database, the system initializes in Commerce Server 2002 Profiles compatibility mode.
In a Profiles schema, expressions are loaded from the es_ExprInfo table in the BizDataStore (Profiles) database.
In a Marketing schema, expressions are loaded from the mktg_expression table in the Marketing System (Campaigns) database. In this case, expressions are loaded from the database referenced in the Campaigns resource.
