RDBMS dodges cache delays by using memory

The Angara Data Server, a relational database management system from Angara Database Systems Inc. of Palo Alto, Calif., avoids disk-caching bottlenecks by using main memory as its primary data store. It saves only log files and checkpoint images on a hard drive.

Company officials said such main-memory databases will become widespread within a few years because of the falling price of gigabyte-level RAM. Even so, hundreds of gigabytes are required per server for superfast analytical and electronic commerce transactions.

The Angara Data Server software runs on multiprocessor servers under SunSoft Solaris, Microsoft Windows NT, Hewlett-Packard HP-UX, IBM AIX and Linux. Clients can have any of those operating systems or Windows 9x.

A Structured Query Language programming interface permits integration with existing databases.

The RDBMS supports unlimited numbers of tables, rows and indexes and up to 1,024 client connections.'

The data store can be as large as 2G on 32-bit platforms or limited only by system memory on 64-bit platforms. A free trial copy of Angara Data Server 3.0 is downloadable from the Web at www.angara.com/angara/product/dwn_frame.htm.
