database - Do web applications create a new table for each users data? -

-

sorry in advance if silly question, new web-application design.

in web-apps users able create , manage own data, how database/back-end implementation work?

e.g. in web-application: user able create list of tasks , time complete them by.

should end creating new table *each user'*s tasks?

i ask surely data different users should seperated each one?

you can have table, containing tasks when user creates new task/list of tasks or whatever call them new entry added table
