⚡ Databases

Databases are software systems designed to store, organize, and retrieve data efficiently while maintaining consistency, durability, and reliable transaction handling across applications and services.

They support querying, indexing, caching, replication, backup and recovery, access control, and scalable architectures for handling large volumes of data and simultaneous requests.

According to our statistics, databases are detected on 43.5% of all websites.
92.3% of these sites use only one database, 2.4% use two, and 5.3% use three or more of them.

Statistics based on 3.5M+ analyzed websites. About this data

Please note that it is not always possible to identify the database used by a website, as it is a backend technology. Also, many content management systems support multiple database types. Therefore, we only detect the database if we have sufficient confidence that it is being used.
