Why are (relational) databases preferred over keeping the data in memory? (feddit.de)

Why do so many programs use relation databases instead of loading the data during startup and keeping it in memory? Especially for smaller datasets I would think, that a database adds unnecessary complexity and overhead. Also, a lot of data can be saved using modern RAM and when using an in-memory approach, optimized data structures can be utilised to further improve the performance

Edit: yes I meant relational databases

Like everyone has mentioned, because you want the data to persist across program runs.

RDBMS do not imply persisted data. There are plenty of databases which support or are designed explicitly to work as in-memory data stores. Perhaps the most popular one is SQLite, whose in-memory store is a popular choice.
