Performance of system

Hi,
I am developing an editorial system(MS-SQL). There are a public part(frontend for reader) and an editorial part (backend for editor, admin,...).
The public part of system will be used approximately 1000 acesses/s.

A possible solution:
I solve whether I have to use two databases:
1.DB all data
2.DB with data for frontend

acesses............trigers
--->2.DB <----1.DB

or more of databases or else?

The purpose is, a reader should have good response that the reader don't wait.

Could you give me any advice ?
Thanksone database

make sure all tables are properly indexed for performance of your main queries|||and is there any at least one reason for more database ??|||separate database can be backed up and recovered separately
