sql.js - SQLite compiled to JavaScript through Emscripten

•    Javascript

sql.js is a port of SQLite to JavaScript, by compiling the SQLite C code with Emscripten. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a javascript typed array. There is no C bindings or node-gyp compilation here, sql.js is a simple javascript file, that can be used like any traditional javascript library. If you are building a native application in javascript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to javascript.

ActorDB - Distributed SQL database with linear scalability

•    Erlang

ActorDB is ideal as a server side database for apps. Think of running a large mail service, dropbox, evernote, etc. They all require server side storage for user data, but the vast majority of queries is within a specific user. With many users, the server side database can get very large. Using ActorDB you can keep a full relational database for every user and not be forced into painful scaling strategies that require you to throw away everything that makes relational databases good.

MyRocks - Facebook's branch of the Oracle MySQL v5.6 database

PipelineDB - The Streaming SQL Database

•    C++

An open-source relational database that runs SQL queries continuously on streams, incrementally storing results in tables. PipelineDB stores only the output of continuous queries, which are incrementally updated as data is ingested. The database’s size is independent of the amount of data ingested over time. It is built into the PostgreSQL core and can be used as a drop in replacement for PostgreSQL without making any application code changes.

DbLite

DbLite is a port of a very light weight relational database management system from Java to J#. It has a SQL-like syntax and uses serialization to manage tables. It is not meant to compete with real-world relational database management systems, rather provide simple, stand-alon...
