8Domain Modeling review

How to create new types:Define “completely new types”:

<itemtype code="Car">

(implicitly extends from GenericItem)

Define a type by inheriting from already existing types, such as:

<itemtype code="Car" extends="Product">

Extend existing types:By adding attribute definitions to existing types (attribute

injection):

<itemtype code="Product" …>

…<attribute qualifier="MyAttribute">

10System Initialization & Update

Initialization:

ALL database tables are dropped.

New tables and an empty system are created (only type definitions and the admin & anonymous user).

Data model is created from scratch as defined in the items.xml files.

Existing data model definitions will be lost!

Update:

Adds newly defined types to the type system definition in the database.

Modifies type system definition in the database to match the definition in the domain model.

No loss of data!
