Readers, Some advice would be appreciated about appropriate tables to store temporary data. Scenario: User copies csv file of user data, presumably into some temporary table(s); User selects data (read-only) from extant tables; Web server combines user data with read-only data to produce content visible to user as html and/or pdf document; User does not need to sign in to use web page, only the user e-mail address; User data deleted (including e-mail address) after time (e.g. 24 hours) and/or user selects to receive combined data via e-mail (after which all user data is automatically deleted). What part of the documention would be most relevant to read firstly, please?
