<div class="section"><p>There are many more tools available than are on this list, and
every tool in the marketplace has its own strengths, weaknesses, and performance
characteristics. But most have one thing in common: support for ODBC database
servers. However, because ODBC serves as a common denominator for various
database management systems, and because there are subtle differences from
one ODBC driver to the next, many tool providers write to the more common
ODBC and <span class="keyword">SQL</span> interfaces.
By doing this, they avoid taking advantage of a unique characteristic of a
particular database server. This may ease programming efforts, but it often
degrades overall performance.</p>
