In a computer-based information system where a client application accesses data in a network data modeled database via a data-access system utilizing bookmarks, methods are disclosed for allowing the data-access system to access logical-relationship data and metadata in a network data modeled database, and to present the accessed logical-relationship data and metadata to the client application in a format recognized by the client application. Other methods are disclosed for allowing a client application to access a table referenced by a network data modeled database via a data-access system utilizing bookmarks, and to modifying a logical relationship link to the accessed referenced table. In this way, a client application can directly access and modify logical relationship data stored in the network data modeled database via a data-access system utilizing bookmarks.
