Description
Computer-based information technologies have been extensively used to help industries manage their processes and information systems hereby - come their nervous center.
More specially, databases are designed to s- port the data storage, processing, and retrieval activities related to data management in information systems.
Database management systems p- vide efficient task support and database systems are the key to impleme- ing industrial data management.
Industrial data management requires da- base technique support.
Industrial applications, however, are typically data and knowledge intensive applications and have some unique character- tics that makes their management difficult.
Besides, some new techniques such as Web, artificial intelligence, and etc. have been introduced into - dustrial applications. These unique characteristics and usage of new te- nologies have put many potential requirements on industrial data mana- ment, which challenge today's database systems and promote their evolvement.
Viewed from database technology, information modeling in databases can be identified at two levels: (conceptual) data modeling and (logical) database modeling.
This results in conceptual (semantic) data model and logical database model.
Generally a conceptual data model is designed and then the designed conceptual data model will be transformed into a chosen logical database schema.
Database systems based on logical database model are used to build information systems for data mana- ment.
Much attention has been directed at conceptual data modeling of - dustrial information systems.
Product data models, for example, can be views as a class of semantic data models (i. e.
