MongoDB has a document-oriented database which indicates that you won't have to worry about the Data Structure, the number of fields, or the kinds of fields used to record values while storing your data. By merely introducing new fields or removing existing ones, you can alter the shape of records. MongoDB's Store Arrays functionality makes it simple to describe hierarchical relationships, save arrays, and other complicated data structures.

MySQL is based on SQL and may be used for a variety of tasks like eCommerce, data storage, and web database management. It is a web application that runs on a server. It is used by organizations with a large amount of data that must be handled and utilized in large applications. Scalability and execution speed are both high in MySQL. Because MySQL is so widely used, there are a plethora of third-party programs that can help with development.

MariaDB expands from standalone databases and data warehouses to completely distributed SQL, allowing millions of TPS and dynamic, ad hoc analytics on millions of rows to be performed.

SQLite is a relational database management system that runs without a server. It's an in-memory open-source library that requires no installation and requires no configuration. It's also quite handy because it's only 500kb in size. After installation, the software does not require a license. SQLite is serverless in that it does not require a separate server process or system to run. It allows you to work on numerous databases at the same time in the same session, making it versatile.

Apache Cassandra is an open-source NoSQL system that's simple to use and supports replication across several data centers and cloud availability environments. The platform is fault-tolerant when data is duplicated across numerous nodes. Cassandra was created for Facebook, although it may be swiftly deployed across several servers. You need not have to worry about inefficiencies in the system because each node in the cluster works independently.

Firebird offers excellent concurrency, high performance, and powerful language support for stored procedures and triggers. It has been used in production systems, under a variety of names since 1981.

Firebird is a commercially independent project of C++ programmers, technical advisors and supporters developing and enhancing a multi-platform relational database management system.

Elasticsearch is the key component of the Elastic Stack, a suite of free and open tools for data intake, enrichment, storage, analysis, and visualization. It is known for its easy REST APIs, distributed nature, speed, and scalability. The Elastic Stack currently contains a comprehensive set of lightweight shipping agents known as Beats for sending data to Elasticsearch, which is sometimes referred to as the ELK Stack (after Elasticsearch, Logstash, and Kibana).

Memcached's APIs provide a huge hash table that is distributed across multiple computers. When the hash table is full, subsequent inserts cause older data to be removed in the least recently used (LRU) order. In Memcached applications, requests and additions are frequently loaded into RAM before falling back on a slower backup store, such as a database. There is no internal way in Memcached for tracking potential misses. Some third-party utilities, however, provide this service.

Hadoop allows clustering several computers to analyze big datasets in parallel, rather than requiring a single large computer to store and analyze the data. Hadoop makes it easy to make full advantage of cluster computers' storage and processing capabilities, as well as to run distributed operations on massive volumes of data. Hadoop offers the foundation for the development of various services and applications.

The business InfluxData developed InfluxDB, an open-source time-series database (TSDB). It's developed in Go for storing and retrieving time series data in domains including operations monitoring, application metrics, Internet of Things sensor data, and real-time analytics. It also supports the processing of Graphite data. There are no external requirements for InfluxDB.For querying a data structure, it provides a SQL-like language with built-in time-centric operations.

CouchDB is a document-oriented system that can be used as a stand-alone programming interface or in conjunction with high-volume distributed applications, especially online applications that handle large amounts of loosely organized data.

For longevity and security, CouchDB stores data in JSON format and depends on sessions and authentication. Users of CouchDB have expressed dissatisfaction with the user interface and the absence of a full-stack search.

ArangoDB is a graph database that includes a SQL-like query language as well as a versatile data model for main values, graphs, and files. It features a simple cluster configuration. ArangoDB has a significant user base and has a built-in search engine as well as a microservices architecture. You can execute graph analytic questions and decrease the number of database technologies utilized in the production system when you use ArangoDB.
