Abstract
A telephone switch system is connected digitally to an external computer system operating database software and having access to a digitally stored database of information used by the switch. The switch performs data transactions on the database in the manner of a client. The database engine allows live queries, which automatically update querying clients as pertinent data changes. The database engine also allows query concentration, which caches query results and supplies the cached results to querying clients making identical queries within a prescribed period of time. The database engine further allows batch inserts, which allow a user to add a plurality of records with a single command.
