- Abstract
- Today's enterprises employ multiple information systems which are independently developed, locally administered, and are different in logical or physical design. To share information across organisational boundaries requires a global query system capable of providing online intelligent assistance to users. Conventional technologies such as schema based query languages and hard coded schema integration are insufficient. Develops a model assisted global query system using an online repository of enterprise metadata, the metadatabase, for global query formulation and processing with adaptiveness and open systems architecture. Presents a definition model for the metadata as a knowledge system. Analyzes the improvements of the new system in relation to the old. Tests a prototype system in a computer integrated manufacturing setting
