Empress Achieves Faster Performance with In-memory Speedup

Empress's ability to work in memory delivers speed and power to time-critical applications

Greenbelt, MD - The EMPRESS RDBMS (Relational Database Management System) allows users to intermix main memory and disk storage mechanisms for all data management functions. Users have the ability to utilize Empress completely in main-memory; or, users can select exactly which components of their Empress database they wish to store in memory and which they would like to store on disk depending on their own unique needs.

For developers of real-time applications who need to process information rapidly, working with Empress in memory is ideal. Users can choose to put a whole Empress database, including all its tables and indices, in memory. In addition, applications, the database engine, utilities and libraries can reside entirely in memory. Via this method, information can be readily made available and manipulated in less time since access to information via in- memory is much faster than disk.

Alternatively, certain Empress components needed to perform specific processes can be placed in memory while others are accessed through disk. For example, relational database processing in Empress can take place in memory while operations for data backup and recovery can be stored on disk. Through this method, database processing is quicker, but recovery of data, should the particular workstation fail or crash, is still well protected.

"Utilizing In-memory can be the key to optimizing performance and increasing speed within real-time applications which must process up-to-the minute data," states Empress Software President and CEO, John Kornatowski. "With the price of memory continuously decreasing and 64-bit hardware becoming more available, it is reasonable to run very large applications in memory. Users have a significant choice in using full or partial In-memory database applications with Empress's 64-bit ports to machines such as HP, SGI, DEC Alpha UNIX and Cray."

Empress also features a small, compact database engine which requires less than 1MB of RAM itself for real-time developers. This small footprint, combined with the ability to operate totally in memory, delivers the necessary speed for an application managing time- critical information.

Empress Software develops and supports the Empress Relational Database Management System. The Empress RDBMS V8.10 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, space exploration, flight simulation, telecommunications, medical systems, telephony systems, geographical information systems and network management.
