  The topics in the Developing section describe tasks performed by an application developer.
  - Functional architecture
    Functional architecture provides both the set of patterns used to implement the business functionality and the frameworks in which these business functions execute.
  - Persistent object model
    WebSphere Commerce deals with a large amount of persistent data. There are numerous tables defined in the current database schema. Even with this extensive schema, however, you might need to extend or customize the database schema for your particular business needs.
  - Presentation layer
    WebSphere Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
  - Controller layer
    The Controller layer is the conductor of operations for a request. It controls the transaction scope and manages the session related information for the request. The controller first dispatches to a command and then calls the appropriate view processing logic to render the response.
  - Business logic layer
    The business logic layer is the business components that provide OAGIS services to return data or start business processes. The presentation layer uses these OAGIS services to display data, or to invoke a business process. The business logic provides data required by the presentation layer. The business logic layer exists because more than just fetching and updating data is required by an application; there is also additional business logic independent of the presentation layer.
  - Persistence layer
    The interaction between the business objects and persistence layer is isolated in an object called the Business Object Mediator. Business object document (BOD) commands interact with the Business Object Mediator to handle the interaction with the logical objects and how they are persisted.

      B2C, one of the predefined business models in WebSphere Commerce, supports commerce transactions involving products, services, or information between businesses and consumers. Consumers typically purchase goods or services directly from a business in a B2C scenario.
    - B2B direct information model
      B2B direct, one of the predefined business models in WebSphere Commerce, supports commerce transactions involving products, services, or information between two businesses or parties. Typical B2B direct transactions occur between buyers, suppliers, manufacturers, resellers, distributors, and trading partners.
    - Extended sites information model
      Extended Sites, one of the predefined business models in WebSphere Commerce, is used when a seller can have many sites that are aimed at different audiences. For example, a seller can create sites that are based on geographical regions, while some customized sites can be created for individual large customers. All these different sites can share assets such as the catalog. Each site can select the subset of the catalog that is presented, and adjust the prices as necessary.
    - Relationships between stores
      A Store Relationships package. A store relationship (captured in the STOREREL table) is the relationship between two stores. All store relationships are directional. In each store relationship, one store provides the services and the second store in the relationship uses those services. For example, store A uses the catalogs that are provided by store B. Store relationships are specific to a particular Store, and thus the Store Relationships package is shown as dependent on the Store.
  - Business models
    Before starting to develop your site with WebSphere Commerce, you need to determine the business model supported by WebSphere Commerce that best represents the purpose of your site. Usually sites created with WebSphere Commerce will be implemented based on of one of these business models.
  - Store data information model
    Store data is the information that is loaded into the WebSphere Commerce Server database, which allows your store to function. The URL Registry Entries and View Registry Entries packages are included in the diagram, but they are not database assets. These entries are presentation configuration (that is, struts actions and forwards) that must be deployed. URL registry entries are shown in the diagram to illustrate the entire store data information model. To operate properly, a store must have the data in place to support all customer activities. For example, in order for a customer to make a purchase, your store must contain a catalog of goods for sale (catalog data), the data associated with processing orders (tax and shipping data), and the inventory to fulfill the request (inventory and fulfillment data).

B2C information model

B2C, one of the predefined business models in WebSphere Commerce, supports commerce transactions involving products, services, or information between businesses and consumers. Consumers typically purchase goods or services directly from a business in a B2C scenario.

The following diagram shows a UML representation of the B2C information model.

Diagram showing the B2C information model

Root organization: All organizations in the business become descendents of the root organization. The site administrators who maintain the online site, are owned by the root.
Default organization: All of the business' customers are owned by the default organization. The default organization is a child of the Root Organization.
Seller organization container: A Seller organization container holds any number of seller organizations. By having stores under different seller organizations, you have more flexibility in terms of access control for customers as well as administrators.
Seller organization: A seller organization is created to own all the stores (Retailer) and the administrators who maintain the store. The administrators who maintain the store's functions (for example customer service representatives, catalog and product managers) are termed Seller administrators and are owned directly by the Seller organization.
Customer facing store: The storefront from which customers shop.
