Non-traditional database management systems (DBMSs) are being increasingly used for application areas such as computer aided design, geographical data and multimedia presentation. In an environment consisting of both traditional and non-traditional DBMSs, application programmers must deal with diversity of the systems. Moreover, a non-traditional DBMS affects the performance of other systems because of its long duration transactions and large, non-uniform data objects. CORDS aims to address these problems and implement a multidatabase system (MDBS) consisting of both traditional and non-traditional DBMSs.This paper deals with concurrency control of large, non-uniform data objects in a MDBS. It proposes a logical concurrency control framework to efficiently handle these objects. With this framework, it is possible to share data objects at a finer granularity than that supported by a local database system. We consider local database systems based on locking and present concurrency control and recovery aspects of the framework.
