DEVICE FOR HYBRID REPLICATION OF REPLICATED DATABASE, COMPUTER MOUNTING METHOD, AND COMPUTER SOFTWARE PROGRAM

摘要

PROBLEM TO BE SOLVED: To use a combination of synchronous and asynchronous replication in order to replicate a local database to a replicated database. SOLUTION: The typical tradeoff between synchronous and asynchronous replication is optimized by using hybrid replication. The hybrid replication is to use the synchronous replication for inserting new data and the asynchronous replication for updating existing data. The combined use of synchronous and asynchronous replications in this manner provides an efficient replicated database where the replicated database can tolerate some delay in data updates but requires "no data loss" of new data.
