Question

I know there are many queries related to this question but my problem
is different.I want to make a Password Manager application which
stores host name,username,password,notes etc for each user. I can not
store these information in user’s column as there are multiple rows
for each user’s data.

So is it right in my case to create a separate table for each user
or I create a single table named “Host” and add all passwords there
with foreign key “username” as primary key in this table.Whenever any
query is executed it display only particular user’s rows.

User Table:- id:username:email:password:security question:answer

Host Table:- username:s.no.:host name:host username:password:notes

Which approach would be more effective and if there an better
alternative please let me know.I am posting my question first time
after gaining a lot from this website so please excuse me for my bad
grammar.

Answer 1

A correct approach would resemple something like this:

Users
------
id | username | email | encryptedpassword | security_question | encryptedsecurityanswer

Hosts
------
id | user_id | name | notes 

Ceate a table for users and hosts. These tables are joined by the Users.id to Hosts.user_id relationship.
