This page presents several common relational database management systems (RDBMSs) and NoSQL databases.

For an introduction to RDBMSs and NoSQL databases, see Properties of RDBMSs and NoSQL databases.

The following list describes popular SQL and RDBMS databases:

Oracle: An object-relational database management system (DBMS) that is written in the C++ language.
IBM DB2: A family of database server products from IBM.
Sybase: A relational database server product for businesses that is primarily used on the Unix operating system.
MS SQL Server: An RDBMS for enterprise-level databases that supports both SQL and NoSQL architectures. MS SQL Server was developed by Microsoft.
Maria DB: An enhanced, drop-in version of MySQL.
PostgreSQL: An enterprise-level, object-relational DBMS that uses procedural languages such as Perl and Python in addition to SQL-level code.

The following list describes popular NoSQL databases:

MongoDB: The most popular open-source NoSQL system. MongoDB is a document-oriented database that stores JSON-like documents in dynamic schemas. Craigslist, eBay, and Foursquare use MongoDB.
CouchDB: An open source, web-oriented database developed by Apache. CouchDB uses the JSON data exchange format to store its documents; JavaScript for indexing, combining, and transforming documents; and HTTP for its API.
HBase: An open source Apache project that was developed as a part of Hadoop. HBase is a column store database written in Java. It has capabilities similar to those that BigTable provides.
Oracle NoSQL Database: Oracle’s NoSQL database.
Cassandra DB: A distributed database that excels at handling extremely large amounts of structured data. Cassandra DB is also highly scalable. Cassandra DB was created at Facebook. It is used by Instagram, Comcast, Apple, and Spotify.
Riak: An open source, key-value store database written in Erlang. Riak has built-in fault-tolerance replication and automatic data distribution that enable it to offer excellent performance.
InfoGrid: An open source web graph database for creating RESTful Web applications that use graphed data.
InfiniteGraph: A highly specialized graph database that focuses on graph data structures. InfiniteGraph is useful for finding hidden relationships in big data. It is implemented in Java.
