title: Lightweight SQL server for Raspberry Pi
body: <p>I'm looking for a lighweight database/SQL-server to run on a Raspberry Pi. Since it should be accessible from more than one application, embedded databases like SQLite would not work, thus it should be a standalone database (I know that SQLite databases can be read by more than one process at the same time, but I'm mostly doing write-operations which would lead to many locks on the file).</p>
  
  <p>From what I found on the web, people seem to advice against using databases like MySQL or PostgreSQL on the Pi for performance reasons. Is there a lightweight database to use on the Pi without slowing down the whole system?</p>
