C++11 wrapper for the LMDB embedded B+ tree database library.
This is a comprehensive C++ wrapper for the LMDB embedded database library, offering both an error-checked procedural interface and an object-oriented resource interface with RAII semantics. • Designed to be entirely self-contained as a single <lmdb++.h> header file that can be dropped into a project. • Implements a straightforward mapping from C to C++, with consistent naming. • Provides both a procedural interface and an object-oriented RAII interface. • Simplifies error handling by translating error codes into C++ exceptions. • Carefully differentiates logic errors, runtime errors, and fatal errors. • Exception strings include the name of the LMDB function that failed. • Plays nice with others: all symbols are placed into the lmdb namespace. • 100% free and unencumbered public domain software, usable in any context and for any purpose.
GigaBASE is object-relational embedded database engine for C++ applications. It provides SQL-like query language, smart C++ interface (loading objects instead of tupples), transaction based on shadowing page algorithm (no separate log file and very fas
Some experimental SQL client generation code for building client packages and other various half completed trials - (mostly around databases, particular Firebird).
Generic Object Oriented Database System Distributed thick-client OODBMS using aspect-oriented approach to build transparent interface to database from OO programming languages (C++, Java, C#)
RAQUEL : "Relational Algebra Query, Update and Executive Language"
The project has 2 related sets of aims. As a language, RAQUEL is to : 1. be a pure relational language (unlike SQL) as defined by Date & Darwen's "The Third Manifesto"; 2. incorporate a generalised extension of the ANSI-SPARC 3-layer DB architecture; 3. have the maximum ratio of functionality to conceptual complexity (as defined by Fred Brooks). As a DBMS, RAQUEL is to : 1. have an Open Architecture, enabling a variety of DBMS configurations of 'black box' code, each installation optimised for a certain kind of DB; 2. have a range of core black boxes to provide general DBMS functionality, & a range of plug-in black boxes to support different physical storage mechanisms & scalar data types; 3. employ code designed with a mixture of functional, OO & other methods so as to minimise internal DBMS state complexity. The project links to a Northumbria University website where the vision, specification & design of RAQUEL have been published.
on-disk memory library using meta-data
meta-treedb can implement malloc functionality, and much more! Need a heap that allocates of a fixed size chunk of memory? No problem. But where treedb comes into its own is when it comes to allocating from a mmap()ed disk file - the memory becomes persistent. If you follow the tests/examples, you too can store dictionaries, trees, lists or whatever you can think of in disk-based memory, just an open() and mmap() away. Meta-treedb comes with an AVL tree, doubly-linked-list and variable-entry-sized-array implementations for you to use in your data structures. So, what distinguishes meta-treedb from treedb? * "class" interfaces for treedb collections These are vtables (virtual function tables) that implement th interface. * faster compiles - only the "class" interfaces are visible to client code This is at the expense of a small performance hit. * the ability to use implementations that were developed after client code was compiled.

A Database System for Metamodeling and Method Engineering
ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS) and University of Aachen (RWTH). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license.
