db4o is an object database for Java and all .NET environments. Its features include ACID transactions, automatic class schema recognition, query-by-example, a S.O.D.A. object querying API, native queries, LINQ support on .NET, callback methods, memory files, cascade-on-delete, multi-threaded access, and Java Webstart and servlet support.
GRASS (the Geographic Resources Analysis Support System) is a software raster- and vector-based GIS (Geographic Information System), image processing system, graphics production system, and spatial modeling system. It contains many modules for raster data manipulation, vector data manipulation, rendering images on the monitor or paper, multispectral image geocoding and processing, point data management and general data management. It also has tools for interfacing with digitizers, scanners, and the PostgreSQL, DBF, and ODBC connected databases. GRASS operates on all common operating systems.
MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
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.
The Easysoft ODBC-ODBC Bridge allows applications on one machine to access ODBC data sources on another. It supports multiple concurrent connections from multiple clients to multiple target databases. The principle application is to enable access from Linux and Unix platforms to remote ODBC databases. For example, Apache/PHP programs on Linux can read/write data held on MS SQL Server on Windows, and Perl programs can read/write data held in a MS Access database. Supported applications include Applixware, Open Office, Python, Rexx/SQL, mnGoSearch, OpenLDAP, and Oracle sqlplus. Supported platforms include Linux, MacOSX, IBM zSeries, Windows and various Unix flavors.
ROOT is an OO framework for large-scale scientific data analysis and data mining. It contains an efficient hierarchical OO database, a C++ interpreter, advanced statistical analysis, visualization, introspection, documentation, networking, and GUI classes. The command/scripting language is C++, and large scripts can be compiled and dynamically linked in. Using the PROOF (Parallel ROOT Facility) extension, large databases can be analyzed in parallel. The system runs on all known POSIX platforms, Windows, and MacOS X.
