A language multidatabase system communication protocol

Rapid growth in the area of multidatabase systems (MDBSs), which involve both the access of global data and distributed transaction processing, has created a need for programming languages that provide communication reliability and powerful synchronization. The requirements of MDBSs are reviewed, and the Vienna Parallel Logic programming language is presented. The ways to realize an MDBS communication protocol in this language are discussed. The Vienna Parallel Logic language incorporates a concurrent logic language, as well as features of both distributed operating systems and database management systems. These features combine to support the communication and synchronization required by distributed transaction processing. The Vienna Parallel Logic language is suitable for use as a general-purpose distributed programming and coordination language.<
