Types of Databases

- NoSQL database
Apache CouchDB
Apache CouchDB is a NoSQL database. NoSQL databases are beneficial for the management of large amounts of distributed and unstructured data. CouchDb was initially released in 2005. The current version 3.1.1 was released in September 2020. It supports cross-platform operating systems.
Apache CouchDB open-source DB employs multiple formats and protocols to store, transfer or process the given data. It is document-oriented. Being implemented in Erlang, CouchDB uses JSON for data storage. Besides, JavaScript is its query language which uses MapReduce. Further, it employs HTTP as its API.
Unlike a relational database, this does not support the storage of data in tables. Instead, it considers each database as a collection of independent documents. The most distinguishing feature of CouchDB is its multi-master replication feature. Thus, it ensures scalability that in turn aids in developing high-performance systems.
MariaDB
MariaDB is the most-used relational database. A relational DB uses a tabular structure for storing data. This ensures easy re-organization and multiple access patterns.
MariaDB is an open-source database that is community-developed. It is highly compatible with MySQL. Thus it matches the APIs and commands of MySQL. Besides, it is inclusive of storage engines such as MyRocks, Aria, and ColumnStore.
MariaDB is developed by MariaDB Corporation Ab and MariaDB Foundation. It was initially released 11 years ago in 2009. However, the stabilized version was released in February 2021. It is compatible with Linux, Windows, and macOS operating systems.
