I had two reasons in mind:
- security (the db user has rights only on its database)
- simplicity (no need to prefix table names or to add a customer column
in every table PK)

Thanks for the reply,
What was your main reason for using separate databases instead of one
single database?

Yes, I have exactly one database per customer and one more for
supervision purpose (where access to customer databases are defined).

Hi,
I have a situation very similar to yours, although I am not sure
about the answer to your question, I have a quesiton for you:
when you say you have several databases, what do you mean? do you
mean one per customer/application?
Thanks

Working on an application that is the same for multiple
customers, I had to face a design option.
I wanted to avoid installing the application as many times as
we had customers (for maintenance reasons).
Therefore I chose to have a unique code installation but
several databases.
Each customer would access its application by adding its
account name to the application base URL:
webapp.domain.com/account1/ <http://webapp.domain.com/account1/>
webapp.domain.com/account2/ <http://webapp.domain.com/account2/>
etc.
Following this URL prefix are the regular MVC parameters, ie:
webapp.domain.com/account1/module/controller/action
<http://webapp.domain.com/account1/module/controller/action>
I define a default route replacement in my Bootstrap
including the account parameter (see below) and retrieve this
special parameter from a FrontController plugin where I setup
the default database adapter.
I encounter a problem with functions that build URLs (for
instance $view->url(...) or $redirector->gotoRoute(...), etc.).
All of these functions should add the current account
parameter at the beginning of the URL, but none of them is
aware of it.
(It should also apply to other functions like
$page->getHref() for Zend_Navigation.)
What design option would you suggest (overload all of these
functions, change dynamically the base URL of the application)?
Thanks for any help

Here is the redefined default route:
$route = new Zend_Controller_Router_Route(
':account/:module/:controller/:action/*',
array(
'account' => 'demo',
'module' => 'default',
'controller' => 'index',
'action' => 'index')
);
$router->addRoute('default', $route);
I would also like to make
"webapp.domain.com/account1/module/controller/action
<http://webapp.domain.com/account1/module/controller/action>"
equivalent to
"account1.webapp.domain.com/module/controller/action
<http://account1.webapp.domain.com/module/controller/action>". I
guess it is possible with the
Zend_Controller_Router_Route_Hostname, but did not try already.
$route = new Zend_Controller_Router_Route_Hostname(
':account.webapp.domain.com
<http://account.webapp.domain.com>',
array(
'module' => 'default',
'controller' => 'index',
'action' => 'index'
)
);
