Information systems have become the nerve center of current computer-based engineering applications, which hereby put the requirements on engineering information modeling. Databases are designed to support data storage, processing, and retrieval activities related to data management, and database systems are the key to implementing engineering information modeling. It should be noted that, howe...
QUICK is a powerful database query tool used to simplify database access. It allows users and applications to formulate high-level queries to relational databases without specifying information about the underlying logical-level structure. This high-level query interface provides substantial cost savings to the applications development and maintenance process. Software development time is decre...
