SQLite is a small, fast, embeddable SQL database engine that supports most of SQL92, including transactions with atomic commit and rollback, subqueries, compound queries, triggers, and views.

The Gaudí Database Visual Editor is a Java application that allows you to visually design the tables of a database using a JDBC 2.0 (or higher) driver. It saves generated diagrams in XML format.

Arad-OneTable-Editor is a set of perl modules to manage and display a dialog for a single-table SQL query. It can verify types, and scroll between the records. The data handling is separate from the dialog class, so it is possible to write different generic dialogs for the same query. A Perl/Tk dialog and a GNU/readline (or plain text) dialog are included in the distribution.
The NCBI C++ Toolkit provides portable libraries and applications for assisting genetic science. These include libraries for networking, SQL and BerkeleyDB access, CGI and HTML handling, ASN.1 and XML handling, sequence alignment engines, sequence retrieval engines, BLAST database engines, FLTK and OpenGL graphics toolkits, and basic system utilities.
openadaptor is a Java/XML-based software platform which allows for rapid business system integration with little or no custom programming. openadaptor can be loosely classified as EAI (Enterprise Application Integration) software. It is highly extensible and provides many ready-built interface components for JMS, Oracle, Sybase, and TIBCO, as well as data exchange formats such as XML.
