Joined or separate databases

2 sites using the same database? or 1 database for each site.

I have developed an articles site with php and mysql. Now I will create another site that will use the same php and database estructure, but not the same content.

I would like to economize server resources. Should I use common or separate databases?

You can use the same mySql installation, but create a separate database within that.
