Method of stratified transaction processing

摘要

The present invention relates to a method of computerized transaction of a collection of a multitude of potentially distributed transactions ensuring the atomicity of the collection of transactions. Besides offering atomic processing behavior the invention optimizes the communication traffic for the coordination of said transactions and the concurrency behavior and throughput of said collection of transactions. The fundamental concept of the current invention for the processing of a collection of potentially distributed transactions encompassed by a global transaction is based on the approach to split the collection of transactions into groups of transactions. Each of the groups is called a transactional stratum or stratum for short. Each stratum is processed and synchronized via an atomic-commit-protocol, thus guaranteeing an ACID processing outcome for each individual stratum. The global transaction, hence structured as a resulting collection of groups of transactions, i.e. as collection of strata, is processed as a set of chained strata according the principles of chained transaction processing. The chained strata execution guarantees an atomic execution of the global transaction.
