title: How to store custom logs to database
body: <p>I would like to ask how you would suggest to save logs of some process (let's say measuring temperatur from multiple weather stations) to database. The problem I have is that I want to have logs immutable so they should be not effected when for example name of weather station changes -&gt; so I guess I would need to create copy of weather station. But I would end up with copy of weather station for each temperatur measurement. Let's say that there would be also some reference temperatur through year stored in weather station so I would need to copy this one too. It would be so wasteful.</p>
  <p>Could anyone help me to solve this problem</p>
