  • Data base locking
    Patent number: 4698752
    Abstract: A data base system is disclosed in which records are locked out during record changing by using a dynamically generated directed acyclic graph of the records. The edges of the graph, stored in the records themselves, point toward a "root" record representing multiply-shared information. An application to the assignment of telephone facilities to telephone subscribers is also described. A transaction list is maintained to identify locked out records previously locked out during the same transaction.
