Berkeley Database
The Berkeley Database is an embedded database system. Its access methods include B+tree, Extended Linear Hashing, fixed and variable-length records, and Persistent Queues. Berkeley DB provides full transactional support, database recovery, online backups, and separate access to locking, logging and shared memory caching subsystems. The program supports C, C++, Java, Tcl, Perl, and Python APIs.

Check Postgres
check_postgres is a script for monitoring various attributes of your database. It is designed to work with Nagios, MRTG, or in standalone scripts.

DBA Companion
DBACompanion is a graphical administration tool for Oracle databases that lets you visualise the contents of a data dictionary. It lets you browse the data dictionary, drill down from one piece of information to related ones, generate SQL scripts based on data dictionary information, and customize all the SQL used by the tool.

Django
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

Elog
ELOG (Electronic Web Lobgook) is an electronic logbook with a Web interface. It can be used to maintain personal or shared logbooks, with the ability to add attachments to logbook pages. Logbook entries can be categorized with user-defined classes, and queried using filters on these classes. Automatic email notifications can be sent on new entries based on these classes. The ELOG server is a small stand-alone C program, which runs under GNU/Linux. The logbooks are saved in plain ASCII files for easy and fast access.

GNU SQL Server Heckert gnu.small.png
Portable multiuser relational database management system. It supports the full SQL89 dialect and has some extensions from SQL92. It provides multiuser access and transaction isolation based on predicative locks. The working OS is Unix; the working language is C. The program also uses RPC, shared memory, and message queues. Note: as of June 26, 2001, this program is no longer being maintained or developed.

Gdbm Heckert gnu.small.png
GNU dbm is a set of database routines that use extendible hashing and works similar to the standard UNIX dbm routines. The library provides also an optional compatibility layer for UNIX-like dbm and ndbm calls.

Gurgle Heckert gnu.small.png
GURGLE (GNU Report Generator Language) is a software package for business applications. It produces database report listings from record and field information from a file. It uses the report to produce (La)TeX-formatted output, plain ASCII text, troff, PostScript, HTML, XML, or any other ASCII-based output format. It may be used for producing large bodies of text where small parts of the text are substituted with information from the database.

GURGLE supports GNUSQL, PostgreSQL, MySQL and CA-Ingres databases. It also has an optional support for Guile.

Kexi
Kexi is a visual database application builder tool by KDE, designed to fill the gap between spreadsheets and database solutions requiring more sophisticated development. Kexi can be used for designing and implementing databases, data inserting and processing, and performing queries. It is part of the Calligra office suite.

Mc 2 Heckert gnu.small.png
MC is a C++ program that creates vector-space models from text documents that can be used for text mining applications. MC provides an efficient multi-threaded implementation that can process very large document collections. The MC program: 1. Recursively descends directories, finding text files 2. Processes files selectively through full regular expression matching of file names. 3. Builds a sparse matrix of word/token counts. The particular sprse marix format used is given here. 4. Processes any user specified text formats(email address or URLs) as a whole token through regular expression matching or FLEX definition. 5. Prunes vocabulary by word length and frequency 6. Excludes user specified stop words 7. Sets word vector weights according any of the txx, txn, tfn, tfx, lxx, lxn, lfn, lfx scaling schemes. 8. Writes all data structures to disk in the Compressed Column Storage format. The application does not have English parsing or part-of-speech tagging facilities or complete documentation
