Xbase DBMS is a collection of specifications, programs, utilities and a C++ class library for manipulating Xbase type datafiles and indices which has been developed and produced by many people from around the world using the internet. This project was formerly known as Xbase for Linux, but as I have recieved input from several people who are compiling this on platforms other than Linux, I have renamed it to Xbase DBMS. The main development of this library however, remains on the Linux platform utilizing the GCC public domain C/C++ compiler.

SQLite is a C library that implements an SQL database engine. A large subset of SQL92 is supported. A complete database is stored in a single disk file. The API is designed for convenience and ease of use. Applications that link against SQLite can enjoy the power and flexiblity of an SQL database without the administrative hassles of supporting a separate database server. Because it omits the client-server interaction overhead and writes directly to disk, SQLite is also faster than the big database servers for most operations. In addition to the C library, the SQLite distribution includes a command-line tool for interacting with SQLite databases and SQLite bindings for Tcl/Tk.

Mimer SQL is an SQL-based, high-performance RDBMS, targeted at mission-critical client/server environments. It offers scalable performance (including multi-processor support), and is available in all major Unix (including Linux), Windows, and OpenVMS platforms.

JCDatabase, Direct File Database Management System has the following advantages over JDBC: 1. JCDatabase does not require you to run a database server or configure your system to provide access to a local database and; 2. JCDatabase can be very conveniently be deployed as part of a traditional client-side application using direct file access.

Bonddb is not a stand alone object orientated database, but works on top of SQL so you still get a solid proven backend with the benefits of things like prescient objects.

GOODS is an object-oriented fully distributed database management system using an active client model. Its multithreaded high-performance database server is language and application independent. The client application interface is built using meta-object protocol and provides transparent persistency for normal programming languages, and the aspect-oriented programming approach used for implementing object access and synchronization policies makes it possible to define various database access strategies fitting requirements of concrete application and separate them from application code itself.

UML2SQL is a Java tool which synchronizes SQL databases with UML diagrams. UML class diagrams can thus serve as authoritative definitions of database catalogs. UML2SQL can be used together with a UML design tool which is capable of producing XMI. For the most generic operations, only a JDBC driver is required for the SQL database. Vendor specific DDL commands for unsupported databases can be easily implemented by extending the DatabaseAdapter class.

Orac is a GUI tool for Database Administrators written in Perl, Tk, and DBI. It organizes many useful DBA scripts into a nice graphical interface, for collecting statistics on your database, or diagnosing problems. It currently supports Oracle, Sybase, and Informix. Richard Sutherland\

FutureSQL is a Rapid Application Development web database administration tool written in Perl. FutureSQL allows one to easily setup config files to view, edit, delete and otherwise process records from a MySQL database. It uses a data dictionary, configuration files and html templates, and allows \"pre-processing\" and \"post-processing\" on both fields, records and operations. It allows multiple views and operations on a data set, including the use of joined tables for queries and reports. A demo application with most of the features is included.

Qddb is powerful database creation software. Using Qddb, you can quickly and easily create database applications. nxqddb allows you to create a complete database application in less than five minutes, and Hx lets you manage database information over the web through a CGI interface. Larger applications can also be developed using Fx, a powerful TCL/Tk toolkit.

MaVerick is a MultiValue database management system.MultiValue databases can be relational, but their method of storing data is much more flexible than the 2 dimensional table you normally associate with relational databases, i.e., you can store multiple fields within a field. On top of which, they are extremely fast in operation.

XDBM is a database designed specifically to handle XML data. It offers greater speed (since the data is stored in a preparsed format), lower memory usage (since only those parts of the file needed are loaded into memory) and faster searching for XML elements. XDBM can also parse and store plain text XML files. XDBM aims to be as close to the W3\
