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.
Bugzproxy is a C# client library for the upcoming Bugzilla Bugtracker WebService interface (part of Bugzilla 3.0). It provides an OO access to a Bugzilla server. The aim of Bugzproxy is to allow easy building of various clients that facilitate the integration of Bugzilla into the various C# tool chains. As the project's aim is to provide an efficient and intuitive OO API, the API probably will change in future revisions.
CodeBase is a high-speed xBASE compatible database engine for C/C++, Visual Basic, Delphi & Java programmers. You can use CodeBase to write high performance database applications that are multi-user compatible with FoxPro, dBASE and Clipper, create anything from a Java applet to a full-blown Windows database application to a simple DOS utility, write scalable applications that can be deployed as single-user, multi-user or client/server, all without changing any of your source code, and port your applications to Windows, DOS, UNIX, OS/2, and Macintosh. There's a free 30-Day Test Drive option available. CodeBase is available for every major operating system including Windows XP, 2000, 9x, NT, CE, DOS, OS/2, Macintosh, and a variety of Linux and UNIX platforms including Solaris, SunOS, HP/UX, AIX, SCO, and others.
FYM is a media organizer that performs quick scans for media files (more than one hundred thousand media files in less than a minute). With its search engine, you easily find and open music, photos, videos, books, and other data types you determine. Covers of music folders and photo albums can be shown. It has strong random functionality.
Gentle.NET is a CLS-compliant, database independent object persistence framework. It has an extensive feature set, excellent performance, and reasonably complete docs. It features automatic SQL generation, object construction/caching/uniquing, validation, bindable list support, relation management, transactions, and much more. Oracle, PostgreSQL, MySQL, Firebird/InterBase, MS SQL Server (incl. CE), MS Access, SQLite, Sybase, and Sybase ASA are supported. It includes a NAnt build file as well as VS.NET project files for building under Windows. Mono 1.1.4 and higher is fully supported.
Greengrass is a C# framework providing a high-level API for the Resource Description Framework (RDF), allowing RDF triples to be parsed, stored, and manipulated. Greengrass supports serialization and deserialization of CLR types to plain RDF, OWL, and other RDF vocabularies. Greengrass should work with any CLR-complied language, like C#, BOO, IronPython, Nemerle, IKVM Java, and VB.NET.
Indigo is a universal organic chemistry toolkit. It contains tools for end users, as well as a documented API for developers. It is based on a cheminformatics library that incorporates a number of unique algorithms developed by GGA Software Services, as well as some standard algorithms well known in the cheminformatics world. The API allows developers to integrate Indigo into their C/Java/C#/Python projects. Two Indigo-based Java GUI applications are provided: Legio (combinatorial chemistry) and chemdiff (visual comparison of two SDF or SMILES files). Three Indigo-based command line utilities written in plain C are provided: indigo-depict (molecule and reaction rendering utility), indigo-cano (canonical SMILES generator), and indigo-deco (R-Group deconvolution utility).
