Deductive Database with Datalog, RA, TRC, DRC and SQL
The Datalog Educational System (DES) is a deductive database with Datalog, SQL, Relational Algebra, Tuple Relational Calculus and Domain Relational Calculus as query languages developed mainly for education. It can be used from most common Prolog interpreters over any supported OS and from portable executables (Windows, Linux and MacOS).
A multi-dictionary system for natural languages (ie. languages that people speak). Operates internally in UTF8, supports querying by particles, customizable in/out filtering, and interface mode (for using with another software) among other features.
Intellect Modeling Kit ~ AI intellect-based apps development suite
Intellect Modeling Kit is an alternative to traditional Artificial Intelligence, intended to build apps assisting human intellect on the steps of its activity: * Observation * Producing propositions based on knowledge * Elimination of impossible propositions * Selection and verification of the most appropriate propositions * Memorizing - converting data to information and new knowledge item creation * Abstraction finding – building artificial objects, representing group of real objects featuring typical signs of group Any human knowledge written and spoken can be uploaded to IMK in a straight way by any expert not familiar with software coding. The IMK components are designed to create ready-to-use software application using simple text files provided by people. IMK accepts human knowledge and develops new knowledge together with people. The activity of IMK could be verified by human expert on every stage. IMK assists intellectual activity, but does not replace us.
ODABA is an terminology-oriented database management system and develo
ODABA is an terminology-oriented database management system (TODBMS) on a high conceptual level. It provides a number of enhanced features based on natural language analysis. Terminology orientation allows designing user oriented data models. Enhanced event model and Active Data Link technology support rapid development of GUI applications. Several development, documentation, test and analyzing tools are provided in order to support developers and administrators. .NET interface and a powerful object-orjented script language (OSI) improve development efficiency.
This library implements several locality sensitive hashing(LSH) based algorithms, including indexing data structure for high dimensional spaces and metric spaces, sketch constructions and set embedding algorithms.
iMeMex is a dataspace management system. iMeMex is a research prototype. The package also provides several useful components for research such as external sorting, B+-trees, inverted indexes, content converters, query operators, and graph indexes.
A high-performance implementation of bloom filters, a lightweight duplicate detection algorithm.
DB Guardian is a Java-based database diagnostic performance tool for Oracle 10g. This tool helps the database administrator (DBA) to monitor and detect problems related to performance in your environments.

IntelliJAF is an extensible platform for building modular and extensible Java applications. It provides a core of plugins/services designed to build with minimum effort client/server applications.
NNDB is a C++ library that provides in-memory data storage and retrieval using syntax that is intended to feel natural for C++/STL, but which also might feel slightly like SQL. Columns types are fixed at compile-time and checked by the compiler.
An easy-to-use object-oriented C++ wrapper for MySQL C API.
OS-independent, cross-platform C/C++ library giving to a hosting application the ability to store and manage any kind of data using label(s). Possible usage-arbitrary datasets storing, versioning, private/shared knowledge-base construction, serialization
Unified DataBase Access Library
XPN is relies on a non relational native XML database, where XML documents are stored in a compressed form and indices enables fast access to structure and content, thus enabling a fast evaluation of XQuery queries.
A very simple db to be used to store, and access data that can be sent between computers. The db itself is designed to be transmitted, therefore the specs call for compactness and checksums. The specs also support digital signatures and compression.
