Open Source C++ Libraries

The fastest and simplest library for SQLite3 in Node.js. Full transaction support. High performance, efficiency, and safety. Easy-to-use synchronous API (better concurrency than an asynchronous API... yes, you read that correctly). Support for user-defined functions, aggregates, virtual tables, and extensions. 64-bit integers (invisible until you need them). Worker thread support (for large/slow queries). Help this project stay strong! better-sqlite3 is used by thousands of developers and engineers on a daily basis. Long nights and weekends were spent keeping this project strong and dependable, with no ask for compensation or funding, until now. In most cases, if you're attempting something that cannot be reasonably accomplished with better-sqlite3, it probably cannot be reasonably accomplished with SQLite3 in general.

The database access library for C++ programmers that provides the illusion of embedding SQL in regular C++ code, staying entirely within the C++ standard.

RocksDB uses a log structured database engine, written entirely in C++, for maximum performance. Keys and values are just arbitrarily-sized byte streams. RocksDB is optimized for fast, low latency storage such as flash drives and high-speed disk drives. RocksDB exploits the full potential of high read/write rates offered by flash or RAM. RocksDB is adaptable to different workloads. From database storage engines such as MyRocks to application data caching to embedded workloads, RocksDB can be used for a variety of data needs. RocksDB provides basic operations such as opening and closing a database, reading and writing to more advanced operations such as merging and compaction filters.

Extension for SQLite to create own functions in PL/SQL.

Tools Slightly Above the Runtime QueryTool for IBM i based on TSAR: http://www.ibm.com/developerworks/ibmi/library/i-extended-dynamic-sql/index.html

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.

An experimental CEP (Complex Event Processing) engine. It implements the event stream processing as a library embeddable in C++ and Perl. Since then it has been renamed to Triceps, so please look at the new location https://sourceforge.net/projects/t

A C++ database connectivity class library supporting different database management systems under a simple interface. The API is hiding implementation details from developers, so class usage is same for each database management system.

Portable C++ RDBMS client library. Provides C++ API and isolates application from low-level DB interactions. Manages database connections, builds and executes SQL statements, parses query results, etc. MySQL, MSSQL, Oracle, SQLite drivers available.

That project aims at providing a framework for SOCI (http://soci.sourceforge.net), so as to ease the packaging and delivery processes, allowing to deliver packages for a great number of Linux distributions, as well as for other Unices and MS Windows.

Allows publishing meta-information about DB, functions and interface of your application, which then can be used by various engines and plugins for providing platform-specific interfaces (CORBA,COCOA,COM,Glib,DBus etc.) without additional R&D effort.

[english] - Jcpp is a libraries set that implement Java's class on C++ language. [spanish] - Jcpp es un conjunto de librerías que implementan clases Java sobre el lenguaje c++.

"Seeker" is an object oriented SQLite wrapper written in C++. It's designed to be very easy and logical to use, while maintaining SQLite's power and flexibility. NOTE: Currently no open source license is chosen; this will be decided soon.

Sybase Open Client Object Oriented Interface (SOOI) The main goal of the project is help to developers, who uses C++ and Sybase Database in theirs works to start it quickly without using complicated API.

An innovative Open Source CEP (Complex Event Processing) engine. It implements the event stream processing as a library embeddable in C++ and Perl. You can think of the Complex Event Processing engine as an in-memory database driven by triggers, or a data-flow machine, or a spreadsheet on steroids (and without the GUI part).

Generic C++ SQL client wrapper over different SQL DB engines. Using a unified interface, it currently supports MySQL/MariaDB, ODBC, PostgreSQL and SQLite.

Relational Object Mapping In C++, is a library that maps database tables to C++ classes seamlessly so that members will be populated by and in return will populate db columns. Also provides many std db operations, directly on the table interface.

Simple ADO wrapper based on Stlsoft library (https://sourceforge.net/projects/stlsoft).

XDBM version 2 will be an XQuery implementation that uses EXIP to handle binary XML in the EXI format adopted by the W3C. It will, like EXIP, aim to be as small as possible so that it runs well on resource constrained devices. It is still in the project design stage.
