  Abstract

A multidatabase system (MOBS) is designed to provide universal access to distributed data across multiple autonomous, heterogeneous local database systems (LOBSs). In this paper, we propose a global concurrency control (GCC) algorithm in MOBS. The proposed GCC algorithm adopts the idea of message ordering in group communication messaging system. A necessary condition of GCC algorithm is that global transactions are serialized in the same order at all LOBSs that they execute. If all operations of a transaction are bundled in a single message and the message arrives at LOBSs in the same order using message ordering property, each LOBS can perform subtransactions in the same order. As a result, message ordering allows to determine easily the relative serialization order of global transactions, and then it can support a local autonomy without any information about the serialization order of transactions executing locally.
