  - 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.
  - Business model information model
    A business model, a representation of the business processes used throughout the site, provides a sample commerce solution which includes an organization structure, default user roles and access control policies, one or more starter stores, administration tools, and business processes that demonstrate best practices. A business model can be customized to support business requirements and scenarios. WebSphere Commerce provides sample business models that show some common commerce solutions. These business models are created by setting up an organization hierarchy structure, access control policies, stores, and contracts that help satisfy the necessary business requirements.
  - 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).
  - Customizing WebSphere Commerce
    You can extend the WebSphere Commerce product to fit your business needs. This topic describes the prerequisite skills and required knowledge that you need to customize business logic. After you have the required knowledge, use WebSphere Commerce Developer to take tutorials that guide you step-by-step through various customization scenarios.

Search index

The WebSphere Commerce Search index is built from temporary tables that read from a search index schema, and build structured and unstructured site content.

Search index types and subtypes

WebSphere Commerce Search contains the following search index types to suit your business and search requirements:

Catalog entry index

A search index for catalog entries in both master and sales catalog.

The catalog entry search index contains the following content:

Structured content: Structured content includes items in the product catalog and delivers search results based on items that are sold in your store.
Unstructured content: Unstructured site content includes documents that do not adhere to a specific data model, such as product attachments contained in various formats. For example, content such as user manuals and warranty information are considered unstructured content. Its elements, construction, and organization are typically unknown and can vary depending on its file type.
Site content: Site content includes HTML and other site files from WebSphere Commerce starter stores. It is fetched and crawled by the site content crawler.

Catalog group index

A search index for categories in both master and sales catalog.

WebSphere Commerce Search contains the following search index subtypes, which keeps data in a separate core for performance reasons:

Inventory

The inventory index, a separate index that contains index data, is an extension of the product index. For accurate inventory status, you can refresh the inventory index more frequently than the product index.

Important:

Non-ATP and DOM inventory systems are supported by index inventory data in WebSphere Commerce Search. ATP, External, and No-inventory types are not supported with the Search inventory index.
The filterCache and documentCache are required when an extension index such as Inventory exists in WebSphere Commerce Search. For more information, see WebSphere Commerce Search performance tuning.

Price

Sets up a subindex for price data. Prices are indexed using Index Load, as it can populate a large amount of data into a separate extension index faster than the Catalog Entry index can index price data. For more information, see Index Load.
