Most database systems (for example SQL Server) locally run a server on your computer, employing the TCP protocol. When you create an application that works with a database, your application will establish a connection with the server and send commands/queries, and the server will perform the database operations and return the results.

There are also serverless databases (for example SQLite). These database systems read and write directly to disk files. In your applications, SQL queries are interpreted (and you would not write the interpretation code yourself, but use an already existing library) and information is just written to, or fetched from, these files as the SQL queries instructed.
