Open Source C++ Frameworks

Make AI-driven decisions using your data, in real-time. At any scale, with unbeatable performance. Vespa is a full-featured text search engine and supports both regular text search and fast approximate vector search (ANN). This makes it easy to create high-performing search applications at any scale, whether you want to use traditional techniques or a modern vector-based approach. You can even combine both approaches efficiently in the same query, something no other engine can do. Recommendation, personalization and targeting involves evaluating recommender models over content items to select the best ones. Vespa lets you build applications which does this online, typically combining fast vector search and filtering with evaluation of machine-learned models over the items. This makes it possible to make recommendations specifically for each user or situation, using completely up to date information.

An ultra fast(0.0002s read/write), small & encrypted mobile key-value storage framework for React Native written in C++ using JSI. This library aims to provide a fast & reliable solution for you data storage needs in react-native apps. It uses MMKV by Tencent under the hood on Android and iOS both that is used by their WeChat app(more than 1 Billion users). Unlike other storage solutions for React Native, this library lets you store any kind of data type, in any number of database instances, with or without encryption in a very fast and efficient way. Read about it on this blog post I wrote on dev.to. Starting from v0.5.0 the library has been rewritten in C++ on Android and iOS both. It employs React Native JSI making it the fastest storage option for React Native. MMKV uses mmap to keep memory synced with file, and protobuf to encode/decode values to achieve the best performance.

EmbedDB is a set of simple APIs for interacting with embedded databases in an intuitive fashion. It aims to implement each language binding in an identical way, enforcing binary compatibility, and leveraging the host language's standard structural types

the goal of this project is to build a stack for Lonworks Protocol and device working on this protocol

MyDBemu is a C++ Library which provides a 'database table'-like Data Type, and methods of data management in a SQL thought.

Set of cross-platform c++ frameworks including database API, XML support, abstracted database backends, report-writer, forms interface and graphing.

DSP stands for Data Server Pages, the APACHE HTTP server module, that provides PL/SQL Server scripting with variable injection preprocessor and features an efficient authorization and authentication framework on the Oracle database backend.

A embedded database implementation, in C++. A database is comprised of ACID-compliant versions of the standard C++ STL containers, presenting a low-level, lightweight API.

"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.

SqLay is a tiny suite of tools for relational database schema visualization or fast data display / entry on console, X or WWW.

The Karoo Project is a framework for making it practical to create distributed applications. By "practical", I mean that it must do it uncomplicatedly, efficiently, and cheaply. This project provides application management, queuing, and IPC.

Sharemind is a secure multiparty computation system that allows you to process data without seeing it. IMPORTANT: The version available on this page is a seriously outdated version that is kept available as an educational tool. More recent versions with more features and better quality are available from http://sharemind.cyber.ee/.

Silicon is a C++ abstraction built on top of high-performance networking libraries. Its goal is to ease the writing of web APIs without compromising on performance. A simple mono-procedure API serving a static string under the route /hello/world. mhd_json_serve is a Silicon backend. It takes an API and serves it with the microhttpd C library. It relies on the JSON format whenever it has to encode or decode objects (procedures parameters and return values). Silicon relies on static objects (i.e. not hashmaps) to model objects. They embed static introspection in their type such that the JSON serializer knows about their members' names and types. In Silicon, parameters are strongly typed and declared next to the procession route. If any error occurs during the decoding (i.e. a missing or ill-formated parameter), the framework does not call the procedure and send an error to the client.

Top Engine the Semantic Web Engine for the Enterprise. Top Engine is a Business Rule Engine that utilize OWL DL ontologies for vocabulary primitive to write rules on top of ontology. Top Engine support forward and backward chaining with truth maintenance

X-VR 2 is a C++ framework, currently it features an RDBMS layer, a Network layer, Platform abstraction layer, Math utility classes and Multi-threading. The framework has been designed to be portable across differen Unix flavors.
