Greenbelt, MD -- Empress Software introduces hot swap replication to Empress RDBMS V8.60. Hot swap replication enhances database performance by delivering data where and when it is needed and providing for swappable masters for maximal uptime. It accelerates data access and protects a company's valuable data because multiple copies of database objects exist within a distributed network as well as multiple copies of the master database. Via hot swap replication, Empress RDBMS users benefit from improved database performance, secure protection of database integrity, and back-up resources in case a principle database server fails or becomes unavailable.

Hot swap replication results in significant performance improvements with faster, more efficient access to data. Data access time is shortened since different applications can call different sources such as a primary database server or local data replicas to get the same piece of data. Network system resources are conserved by reducing the amount of network traffic to any given source, resulting in an overall speed up in data retrieval and throughput.

"Empress RDBMS hot swap replication is the answer for demanding 24 x 7 embedded systems," states Njai Wong, Empress Software's Director of Product Development. "Hot swap replication puts information next to those who really need it. It provides fall back copies of not only replicated data but the master database as well."

Loss of access to corporate data even for a few hours can be paralyzing to a company. Hot swap replication helps to secure continuous access to data by providing one or more back-ups in case a primary database server fails. Local database replicas can be accessed while a primary database is down. Moreover, with Empress RDBMS hot swap replication, a specified replica table can serve as a master table of other replica tables when the principle master database is not available. Priorities can be set in order to determine which database replica will take over as the master of other replicated databases.

Empress Software develops and supports the Empress Relational Database Management System. The Empress RDBMS is one of the most powerful and cost- effective development databases especially designed for embedded systems developers operating on UNIX, Windows or real-time environments. Empress has been utilized successfully in many fields including image and voice management, telecommunications, medical systems, telephony systems, geographical information systems and network management.
