document-oriented - to store, retrieve, and manage data as JSON documents.Non-relational or NoSQL databasesĪ non-relational database is a non-tabular database that uses different data models for storing, managing, and accessing data.

The ACID-compliance is a preferred option if you build, for instance, eCommerce or financial applications, where database integrity is critical. One of the SQL fundamentals is ACID compliance (Atomicity, Consistency, Isolation, Durability).

They are a good choice for building and supporting complex software solutions, where any interaction has a range of consequences. Due to the integrated structure and data storage system, SQL databases don’t require much engineering effort to make them well-protected. However, when the amount of data and user requests grows, the performance may suffer. They also offer improved speed of data retrieval by adding indexes to data fields to query and join tables. Relational databases show great performance with intensive read/write operations on small to medium datasets. Scaling an SQL database between multiple servers (horizontal scaling) can be a challenge as it requires data structure changes and additional engineering efforts.

However, switching from small to bigger machines often involves downtime. Relational databases usually scale vertically, meaning data lives on a single server, and scaling is done by adding more computer (CPU, GPU, and RAM) power to that one server. Here, each record usually holds a value for each attribute, resulting in clear dependencies between different data points.

RDBMSs have a predefined schema, meaning data resides in rows (records) and columns (attributes) with a strict structure. Structured Query Language is the core of these systems as it is used to communicate with and manage these databases, having given birth to their second name - SQL databases. Relational or SQL databasesĪ relational database is a type of data store organizing data into tables that are related to one another, which explains the name. Before discussing the most popular database options, let’s take a closer look at how relational and non-relational database systems differ considering commonly used data structures, performance, scalability, and security. Types of databases: Relational vs non-relationalīasically, there are two types of DBMSs: relational and non-relational, also referred to as SQL and NoSQL respectively. Since databases are just a part of the whole data management strategy, learn about this comprehensive approach in our dedicated article. Concentrating on their business-related benefits and the challenges, we’ll also outline the best use cases for each. The DBMS also contains the key instruments to govern the database.įor our comparison, we’ve picked the 10 most commonly used database management systems: MySQL, MariaDB, Oracle, PostgreSQL, MSSQL, MongoDB, Redis, Cassandra, Elasticsearch, and Firebase. Which database will you choose?Ī Database Management System or DBMS is a type of software that communicates with the database itself, applications, and user interfaces to obtain data and parse it.
