Abstract
The invention comprises a method and system for reducing the apparent complexity faced by a user when confronted by this modeling environment. It provides for a metadata model that represents one or more data sources, the metadata model comprising a query layer combining the functions of a data access layer and a business layer. The query layer includes query subjects that describe how to retrieve data from the data sources, and the query subjects contain query items. The query layer also allows the use of data access language statements which permit the use of more complex computed query subjects and query items.
