Is there a best practice of creating multi tenant application?

Hi,

I have question about creating multi tenant application.

In order to create multi tenant application,

I tried these things:

1. I downloaded 'License Pool Manager' from AppStore , and imported module package into my application .

2. I related 'LicensePool' Entity with all entities of my application.

3. I added "X-path constraint" to each entities such as :

4. I created "before commit event" to all entities, which relate entity to LicensePool entity .

Is there any other solution to create multi tenant application?

I want to know best practice.

Best regards.
