SQLet allows you to directly execute SQL on multiple text files, right from the Linux commandline. In one single command, you can read in text files (with or without header lines) and perform arbitrary select statements, including joins over several files. SQLet can thus replace awk or grep in some instances.
CodeBase is a high-speed xBASE compatible database engine for C/C++, Visual Basic, Delphi & Java programmers. You can use CodeBase to write high performance database applications that are multi-user compatible with FoxPro, dBASE and Clipper, create anything from a Java applet to a full-blown Windows database application to a simple DOS utility, write scalable applications that can be deployed as single-user, multi-user or client/server, all without changing any of your source code, and port your applications to Windows, DOS, UNIX, OS/2, and Macintosh. There's a free 30-Day Test Drive option available. CodeBase is available for every major operating system including Windows XP, 2000, 9x, NT, CE, DOS, OS/2, Macintosh, and a variety of Linux and UNIX platforms including Solaris, SunOS, HP/UX, AIX, SCO, and others.
XML to DDL is a set of Python programs that converts an XML representation of a database into a set of SQL or DDL (Data Definition Language) commands. In addition, it can examine the difference between two XML files and output a sequence of SQL statements (normally ALTER statements) to bring one database up-to-date with the XML schema. You can also download the XML schema directly from the database. Finally, there's a tool to convert your schema into HTML for documentation purposes. XML to DDL currently supports the most recent versions of PostgreSQL, MySQL, Oracle, and Firebird databases.
