Parallel navigation in an A-NETL based parallel OODBMS
説明
A parallel OODBMS has been proposed based on a parallel object-oriented language, A-NETL. The OODBMS is designed for a shared-nothing environment. An overview of the database system is described. Accessing object-data in a parallel OODBMS is based on navigation. A parallel navigation algorithm being implemented for use in the system is presented including its features. The algorithm is based on the need to balance the load across all nodes in a parallel OODB accessing objects with set-valued attributes. An analytical evaluation of the features of the algorithm is presented.
