An Optimal Locking Scheme in Object-Oriented Database Systems
نویسندگان
چکیده
In this paper, a locking-based concurrency control scheme is presented for object-oriented databases (OODBs). It is designed for controlling accesses to class hierarchy, which is important concept in OODBs. Based on access frequency for each class, the proposed scheme incurs less locking overhead than existing works, explicit locking and implicit locking, for any OODB environments. In this paper, it is theoretically proven that the proposed scheme performs better than existing schemes.

An effective class hierarchy concurrency control technique in object-oriented database systems
In this paper, we present a locking-based concurrency control scheme for object-oriented databases (OODBs). Our scheme deals with class hierarchy which is an important property in OODBs. The existing concurrency controls for a class hierarchy perform well only for specific environments. Our scheme is based on so called special classes and can be used for any applications with less locking overh...

Concurrency control schemes for object-oriented database systems (OODBSs) used in the area of performance-critical applications should increase the degree of concurrency and decrease locking overhead in order to offer maximum performance. However, most commercially available OODBSs use conventional concurrency control schemes that never exploit the rich semantics of object-oriented data model, ...

متن کاملMultigranularity Locking with the Use of S emantic Knowledge in a Layered Object
Object-oriented database programming languages use a data model that, by its nature, leads to a hierarchical organisation of persistent data. The Multigranularity Locking (MGL) protocol is the concurrency control framework that allows to better analyse concurrent accesses to such hierarchy of data items. Furthermore, modern Object–Oriented Database Management Systems are organised accordingly t...
