How to create New Database for job portal based on Industry

[Rajasekaran R]

Hi all

I have planned to create the job portal based on Industry like IT ,Pharma,banking,Airlines,Sales.

Option 1:

I have decided to create the seperate DB for each Industry but maintain the user account details in common DB

For example , Main DB is jobportal contains all useraccount details and common tables like country ,state ,city,designation in common Db

other 5 DB are IT ,Pharma,banking,Airlines,Sales .

Connect Main DB with all other DB..

option 2 :

Maintain all tables in Single DB only.But problem is job posting details different from industry to industry .so we cannot maintain common table for all industries..not only jobposting ..some other tables all same type of problem ..

option 3 :

Maintain Completly seperate DB for each Industries.. No relation between all DB..

Which one Best? Pls guide me regarding this..


Thanks
