  Abstract

In the multidatabase system(MDBS), local autonomy and global consistency are important issues. Global consistency could be maintained by a local concurrency control algorithm and a global recovery algorithm. In this thesis, we propose a global concurrency control algorithm to ensure local autonomy and to guarantee global serializability, and a global recovery algorithm which is possible to recover the multidatabase from any failures. The proposed global concurrency control algorithm uses bottom-up approach, based on three-level transaction processing model. It can produce a local history that the execution order of subtransactions is identical to their seialization orderby using dummy-operations in the server when an indirect conflict is caused between subtransactions due to local transaction. At the global module, it can efficiently validate global serialization of global transactions by checking global serializability only for the global transactions which conflict with each other.
