Metakit is an embedded database library with a small footprint. It fills the gap between flat-file, relational, object-oriented, and tree-structured databases, supporting relational joins, serialization, nested structures, and instant schema evolution. Metakit stores individual columns separately (column-oriented architecture).

MapD Core is the foundational element of a larger data exploration platform that emphasizes speed at scale. By taking advantage of the parallel processing power of the hardware, MapD Core can query billions of rows in milliseconds. Furthermore, by using the graphics pipelines of GPUs, MapD Core can render graphics directly from the server.

It is a scalable, distributed, versioned, column-oriented store modeled after Google's Bigtable and runs on top of HDFS (Hadoop Distributed Filesystem). It features compression, in-memory operation per-column. Data could be replicated between the nodes. HBase is used in Facebook and Twitter.

You may be interested in a sister project, IonDB - A key-value store for embedded devices. LittleD is a relational database for microprocessor devices, using as little as 1kB of RAM for most queries. LittleD supports SELECT-FROM-WHERE syntax, including inner joins, projections, and selections over arbitrary expressions. LittleD also has support for CREATE TABLE and INSERT statements. Only integers and fixed-width strings are supported at this time. In the future, query pre-compilation, network transmission, network relational operators, aggregation, and improved indexing are hoped to be implemented.
immudb is a database with built-in cryptographic proof and verification. It can track changes in sensitive data and the integrity of the history will be protected by the clients, without the need to trust the server. It can operate as a key-value store or as relational database (SQL).

Forming a cluster is very straightforward, it gracefully handles leader elections, and tolerates failures of machines, including the leader. rqlite gives you the functionality of a rock solid, fault-tolerant, replicated relational database, but with very easy installation, deployment, and operation. With it you've got a lightweight and reliable distributed relational data store. Think etcd or Consul, but with relational data modelling also available.

It is column-oriented and allows to generate analytical reports using SQL queries in real-time. Large queries are parallelized using multiple cores, taking all the necessary resources available on the current server. It supports distributed processing, data can reside on different shards. Each shard can be a group of replicas used for fault tolerance. All shards are used to run a query in parallel, transparently for the user.

database column-store data-mining relationalRedBeanPHP is an open source ORM (object relational mapping) tool for PHP. It focuses on simplicity and ease of use. What makes RedBean unique is that it creates your database schema on-the-fly. It scans your data and adjusts the column types to fit your object properties. If your models are stabilized you can freeze the database. This way RedBean is easy to develop with but is also extremely fast on production servers.

While a persistent memory model designed mostly for Knowledge management, Artificial Intelligence and Semantic web projects, it can also be used as an embedded object-oriented database for Java projects of all sizes. It could also be used as graph database or as (non-SQL) relational database.
