@Khalifa_hassan: As for design: the table names are generated based on a simple convention: table names start with the name of the module that hosts the entity (the classes stored in the Models folder and end with Record), followed by the name of the entity class. I don't know if there is a scientific name for this convention, but what do you think of: "Modular Schema Definition Design Pattern' for a concept name.

The Orchard database does not follow any normalization rules, as these are rules for relational databases. Orchard uses the Repository design pattern and persists data through nHibernate, an ORM library that uses SQL tables just for data storage. As a matter of fact, the Orchard database breaks all normalization rules. For example, the Settings column in the Settings_ContentPartFieldDefinitionRecord table breaks 1NF; it has repeating groups.

Not that I know of, although other CMS such as Drupal do it in a similar way.
