I hope this is the right stackexchange place to ask.
Im really new using databases and I have a little question: Where to save the user data? I mean, if Im logged as "Foxandxss" on my app, and I want the list of my... questions... How it knows the questions that are mine?
I ended with a "Owner" column in the table with the data. I filter the rows comparing Owner with the current logged user. For one table maybe is OK but if I have like 5, is quite overkilling.
So, how is the typical database that manage user data?
