10 Most Popular Databases to Use in 2025

In the past, two main types of databases existed: set-oriented and relational. Both types had different internal structures. In set-oriented systems, a person could look at information about a certain employee’s salary history in a group. In relational databases, the user can see business-related information. It became easier to reconstruct previous levels with these new structures. Afterwards, relational databases replaced set-oriented systems with multiple tables connected by logical keys.

The relational database became dominant in the 1980s, delivering rich indexes and efficient queries. It introduced table joins and other methods of storing records. The transactional nature of databases became so important that it defined the language of data. Developers learned to write and query in SQL, offering strict guarantees and limits. This foundation led to modern databases, which have become essential for growing businesses.
