GMTM: A grid transaction management model

Abstract

A grid database is a collection of logically interrelated databases (distributed over a grid environment) which is heterogonous, autonomous and contains replica. Special treatments in activities such as transaction management are necessary. In such an environment, each site itself should handle requests, collaborate with others, and follow up transactions. Despite importance of transaction management aspect in grid databases, no appropriate model is proposed yet. In this paper a transaction management model is presented for grid databases. It has a vast range of decision making and scheduling constructs to support all types of transaction activities with high performance. Activities such as forwarding, delegation, conditional commit, and compensation are supported. © 2008 Springer-Verlag.
