FreeTDS - FreeTDS FreeTDS is an open source (or free software if you prefer) programming library, a re-implementation of the Tabular Data Stream protocol. It can be used in place of Sybase's db-lib or ct-lib libraries. It also includes an ODBC library. It allows many open source applications such as Perl and PHP (or your own C or C++ program) to connect to Sybase or Microsoft SQL Server. FreeTDS is a source code library, though, not a binary one. It has to be linked to a program. For it to be useful to you in any way, you have to be prepared to break out your build tools.

Microsoft SQL Server - with no tools to administor it. MS SQL Server uses a variety of SQL called T-SQL, or Transact-SQL, a superset of SQL-92 (The ISO standard for SQL, certified in 1992). T-SQL mainly adds additional syntax for use in stored procedures, and affects the syntax of transactions support. (Note that SQL standards require atomic, consistent, isolated, durable transactions.) MS SQL Server and Sybase/ASE both communicate over networks using an application-level protocol called Tabular Data Stream (TDS). The TDS protocol has also been implemented by the FreeTDS project ([1]) in order to allow more kinds of client applications to communicate with MS SQL Server and Sybase databases. A computer worm named the SQL slammer worm which exploits a security vulnerability in this system was discovered in January 2003, and caused a large Internet.
