fuzzylite is a cross-platform fuzzy logic control library. It provides a natural and simple way of creating a fuzzy logic engine in a few steps using object-oriented programming. It allows you to easily add your own features to the library by just using inheritance. It only relies on the Standard Template Library (STL) which comes with C++. No third-party libraries (e.g., boost) are involved. As a library, it only contains the functions you need from a fuzzy logic controller. qtfuzzylite is a Graphic User Interface which uses fuzzylite to provide a nice and easy way to visually create your fuzzy logic controllers. It allows you to design your fuzzy logic controller and interactively play with it while observing its operation in realtime, and it allows you to export your controller to actual fuzzylite C++ code, so you only need to copy and paste it into your C++ application.
DataNucleus AccessPlatform is a standards-compliant Java persistence product. It is fully compliant with the JDO1, JDO2, JDO2.1, JDO2.2, JDO3, JPA1, and JPA2 Java standards, and provides a REST API. It complies with the OGC Simple Feature Spec for persistence of geospatial Java types. It allows access to all popular RDBMS available today, together with the MongoDB, LDAP, NeoDatis, JSON, Excel/ODF spreadsheets, XML, BigTable, HBase, and Neo4j databases.
TomP2P is a P2P-based high performance key-value pair storage library. Each peer has a table (either disk-based or memory-based) to store its values. A single value can be queried or updated with a secondary key. The underlying communication framework uses Java NIO to handle many concurrent connections.
Jailer is a database subsetting and browsing tool. It is a tool for data exporting, schema browsing, and rendering. It exports consistent, referentially intact row-sets from relational databases. It removes obsolete data without violating integrity. It is DBMS agnostic (by using JDBC), platform independent, and generates DbUnit datasets, hierarchically structured XML, and topologically sorted SQL-DML.
