Pages DB permission help needed

[Gauravk]

Can anyone please help me in setting some strict permission on pages database, either on DB or on page level.

I want certain usergroup to add the records, but member who add the record should only view and edit their own records and not everyone records.

Open to buy any plugin, if it help in setting such granular permissions. 

Thanks in advance.
