THE NEED FOR DATABASE ADMINISTRATION

Most applications—especially those that support enterprise processes enable e-commerce, or facilitate collaboration—are database-intensive and demand optimal performance from the database.

Applications and database queries may utilize very lean and elegant code, but the structure and configuration of your databases can be a detriment to high performance. There are dozens, sometimes hundreds, of configuration settings that need to be optimally tuned to enhance database performance.

When the database is installed, most configuration defaults are applied automatically. Some customization, through various tools, allows users to optimally tune underlying functionality to drive high levels of performance, reliability, and efficiencies. This is where expertise is required, not only to understand the products themselves, but the underlying technologies like cache management, disk and memory allocation, server usage, storage and recovery techniques, and optimal structure and design.

For these technologies, companies either accept the defaults — and the downsides associated with them — or hire expensive in-house database administrators to examine, architect and structure the database so it’s optimized for the deployment environment including critical applications.
