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.
Ice is a modern alternative to object middleware such as CORBA or COM/DCOM/COM+. It is easy to learn, yet provides a powerful network infrastructure for demanding technical applications. It features an object-oriented specification language, easy to use C++ and Java mappings, a highly efficient protocol (including protocol compression), asynchronous method invocation and dispatch, dynamic transport plug-ins, TCP/IP and UDP/IP support, SSL-based security, a firewall solution, and much more.
Af-Arch is an N-tier development framework to quickly build high-quality distributed applications. It currently supports C and C# programming languages, which enables you to write client applications using them. It currently runs on GNU/Linux and Microsoft Windows, and is being used in production environments.
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.
The QueryDOM library is a DOM-based technology whose purpose is the generation of SQL queries at runtime. It's based on a single model representation of the query to be rendered. To represent the SQL query, QueryDOM elements are linked to each other to form a data structure known as the QueryDOM graph, which models the structure of the SQL grammar. The QueryDOM defines types representing the logical structure of the query string in a way that is independent from the specific DBMS. The object model is simple to extend for specific database features.
SDE for Eclipse is a UML modeling environment tightly integrated with Eclipse IDE. It lets you draw all types of UML diagrams (use case diagrams, class diagrams, component diagrams, etc.) in Eclipse, reverse source code (Java, C++, XML, XML Schema, CORBA IDL, etc.) to UML models, and generate Java source from UML diagrams. It features the latest UML notation support, a Rational Rose importer, an XMI importer, Microsoft Visio integration, HTML/PDF documentation generators, and plug-in and template support.
