What is the best way to store data in this scenario:
ACCOUNT table stores id, username, password and a large set of data comprising of multiple rows. Example: multiple sessions stored with date and other information.
What I’m doing now is creating a new table called sessions_id# for each user, but there has to be a more efficient way.
You should be able to create a single sessions table that has a foreign key reference back to the account table. The session table would have columns for an identity, then the user’s ID, then the session-related data (date, context, etc.)
