...communications infrastructure becoming complex demand rises for converging voice, data and multimedia services. Adding to the mix is the fact that information, once largely static in nature, is becoming more dynamic, with the increasing use of personalized subscriber profiles and the growth of content-rich, prepaid and on-demand services.

All of this drives up the sheer quantity of data that must be stored and accessed quickly, reliably and accurately each and every time a service request is made.

In response to these pressures, system vendors are adopting an approach based on open, standard building blocks to shorten time-to-market and reduce the costs of developing and maintaining communications infrastructure. For instance, the Service Availability Forum (www.saforum.org) is addressing this issue by creating, and promoting the industry-wide adoption of, open-standard specifications that facilitate the development and deployment of highly available infrastructure and applications.

High-speed, real-time databases are a central building block in this equipment and provide the data-handling performance required by next-generation networks. These databases also ensure that the challenges of service availability and reliability are met.

Such databases have traditionally been based on proprietary solutions, entailing high development costs and longer time-to-market. Today, infrastructure vendors can benefit from off-the-shelf real-time database products for delivering competitive communications platforms faster and at lower cost.
