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.

This powerful combination helps in providing lightning-fast web and streaming services for organizations searching for ways to heighten and have control over their content delivery at scale while balancing the economic aspect as well.It caches content close to users for faster data delivery.

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.

All SQL Server actions are conveyed to it via a Microsoft-defined format known as Tabular Data Stream (TDS). TDS is an application layer protocol that allows data to be sent from a database server to a client. TDS packets can be wrapped in various physical transport dependant protocols. TDS packets were first created and built by Sybase Inc. in 1984 for their Sybase SQL Server relational database engine, and then by Microsoft in Microsoft SQL Server.

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.

Kx Systems created and markets kdb+, a column-based relational time-series database (TSDB) with in-memory (IMDB) capabilities. High-frequency trading (HFT) uses the database to quickly store, analyze, process and retrieve enormous data volumes. kdb+ can manage billions of records and evaluate data stored in a database. Kdb+ is used by financial companies to examine time-series data like stock or commodities exchange data.

PostgreSQL emphasizes on extensibility and SQL compliance. It has almost two decades of experience which has enabled it to gain a lot of traction. Multi-version concurrency control, SQL for relational questions, and JSON for non-relational questions are all supported. It enables the addition of bespoke functions for various languages such as Java, C++, and others. PostgreSQL is a widely-used open source post-relational server that operates on nearly all operating systems.
