Hi i am building a storage site for people.
Like many others but i was thinking how to build it so had an few questions?

It must be stable on 1 milion users

1. What better to use mysql mssql?
2. Every user his own table or every user his own database?
3. Multiple databases to give every user a databaseID so that i have only 1000 user on an database?

Or do you have eny other idea for an stable database please let me know?

Thank You

Are you planning on using Microsoft type application development (it sounds like you are) or Open Source etc?

Neither. Use Postgresql.
