Berkeley DB (libdb) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications. It includes b+tree, queue, extended linear hashing, fixed, and variable-length record access methods, transactions, locking, logging, shared memory caching, database recovery, and replication for highly available systems. DB supports C, C++, C#, Java, PHP, and Perl APIs. It supports key-value pair (NoSQL), SQL, and Java Object formatted data. It is available for a wide variety of Unix platforms as well as QNX, Android, Mac OS X, and several varieties of Windows.
Easysoft JDBC-ODBC Bridge enables Java applications and applets on any JVM to access any remote ODBC data source, such as MS Access or SQL Server. It is a Type 3 driver certified by Sun Microsystems for use with J2EE™ branded products. The client driver is 100% Java, eliminating the hassle of client side ODBC drivers. It is compatible with any third party ODBC driver and gives multiple concurrent access to multiple data sources from multiple client devices. It is built for commercial use with high transaction rates and dependable performance. It is compatible with all leading Web application servers and Java™ IDEs.
mxODBC is an extension package that provides a Python Database API compliant interface to ODBC 3.5 capable database drivers and managers. In addition to the capabilities provided through the standard API it also provides a rich set of catalog methods that allow you to scan the database for tables, procedures, etc. Furthermore, it uses the mxDateTime package for date/time value interfacing eliminating most of the problems these types normally introduce (other in/output formats are available too). Supported database targets are MySQL, Solid, Sybase, Oracle, Infomix, Adabas, MS Access, MS SQL Server and many other databases with ODBC drivers. Also supported are the Windows ODBC manager and the Unix ODBC managers iODBC and unixODBC, as well as the EasySoft ODBC-ODBC bridge.
Net::Z3950::SimpleServer is a Perl module which implements the server side of the Z39.50 (information retrieval) protocol. It hides the complexity of network exchanges, packet serialization, and session handling. You are required only to implement simple callbacks to support searching and record retrieval. It is the basis of the "Zoogle" project, which is a Z39.50 gateway to the Google web index.
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's DDL::Oracle Perl module has been integrated with the current version for the Oracle side of things, greatly improving the Oracle developer options on the program.
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. A complete database is stored in a single cross-platform disk file. The native C/C++ API is simple and easy to use. Bindings for other languages are also available.
Xbase (formerly known as xdb) is an XBase compatible C++ class library. It provides C and C++ programmers with a cross-platform class and function library for manipulating Xbase type datafiles and indexes. There is support for .DBF and .NDX files (including support for Dbase III and IV memo fields, dates, and record and file locking), and limited support is also supplied for .NTX (clipper index) files. There is also an HTML user interface class which works well with the Apache Web Server.
