نقل قول:

You can decide to use:
- One database for all the websites. In this case, you must specify different database table prefix for each websites.
- Two databases (One master database and One slave database). This architecture is advised when you want to install JMS on an existing website and you are limited in the number of databases you can create (or disk space).
- As many databases than there are websites. This is the most flexible architecture where each websites works with its own database. This is generally the architecture adopted by joomla when you create multiple websites.
The content of each website is totally independent. This means that the content (articles, news, forum, users, ...) are NOT shared.
