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.
Customizing price rules
You can customize price rules to suit the business needs of your site. For example, you can create a new condition or action for business users to add to price rules. Customization is supported for both the Price Rule Builder tool user interface in the Catalog Filter and Pricing tool, and for the pricing services.
Customizing conditions and actions in price rules
To provide business users with more options for price rules, you can create new conditions and actions to use in the Price Rule Builder in Management Center.
List of shipped price rule element templates and task commands
Price rule elements have different requirements depending on their function.

  - 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.
    - WebSphere Commerce Struts framework
      Struts is a well documented, mature and popular framework for building front ends to Java applications. To address concerns in software applications, it uses a Model-View-Controller (MVC) architecture: The Model represents the business or database code, the View represents the page design code, and the Controller represents the navigational code.
    - Spring framework
      The Spring Framework is a lightweight, open source programming and configuration model for developing Java based enterprise applications. This framework is used in WebSphere Commerce for building and configuring Management Center, including the managing of URL requests from Management Center to retrieve and process object data.
    - Management Center
      The IBM Management Center for WebSphere Commerce framework is the foundation for WebSphere Commerce business user tooling. The business objects that are managed with Management Center are defined by the individual components that make up Management Center. The Management Center framework uses these definitions to provide the features that you can use to find, create, modify, and delete the defined business objects. If you plan to customize the Management Center, ensure that you understand the framework and all of the components that make up Management Center.
    - Developing Commerce Composer assets
      Enrich the capabilities of the Commerce Composer tool by developing your own widgets and templates, and extending other features and functions to suit your business needs.
    - Customizing promotions
      Customizing promotions can involve the customization of the promotion business user tools and the underlying promotion engine, which features a clean architecture supporting rich functionality, as well as a wide array of customization possibilities.
    - Working with the promotions component configuration file
      Some Management Center components, like the promotions component, have customizable configuration files. These files contain properties that control certain component features.
    - Customizing marketing
      You can customize marketing features and objects to better meet the business needs of your site. For example, you can customize e-Marketing Spots, customer segments, activities, activity components, such as triggers, targets and actions, and more. Customization is supported for the Marketing tool in Management Center and for the storefront to display e-Marketing Spots.
    - Customizing price rules
      You can customize price rules to suit the business needs of your site. For example, you can create a new condition or action for business users to add to price rules. Customization is supported for both the Price Rule Builder tool user interface in the Catalog Filter and Pricing tool, and for the pricing services.
      - Customizing conditions and actions in price rules
        To provide business users with more options for price rules, you can create new conditions and actions to use in the Price Rule Builder in Management Center.
        Price rule data storage and process flow
        If you are customizing price rules, you should know which database tables store data about price rules. In addition, you should understand what is happening behind the scenes when your store displays a price generated by a price rule. This knowledge helps you understand what you need to create or change to support customized conditions and actions in price rules.
        Price rule element template definitions
        The conditions and actions used in price rules are based on templates. The templates are called price rule element template definitions. If you are customizing a condition or action, you must understand the purpose and structure of these template definitions before you modify an existing template or create a new one.
        Price rule element task commands
        Each condition and action has an associated task command called a price rule element task command. The task command performs the work associated with the price rule element. The price rule element template definition must specify which task command to use.
        List of shipped price rule element templates and task commands
        Price rule elements have different requirements depending on their function. Reviewing details about the conditions and actions shipped with the Management Center can help you understand the requirements for a new price rule element. You can also view the API documentation for any of the task commands.
        Price rule element template parameters
        Price rule element template parameters specify the pieces of data that a price rule element task command needs to perform its function. The pricing services pass the data to the task command when processing a condition or action in a price rule.
        Passing additional parameters to price rule engine
        Customized parameters can pass to the price rule element, by using the request properties in the command context, and the extended data map in the runtime parameters for price rules.
        Adding a new custom condition or action for a price rule
        Add a customized condition or action element to the Price Rule Builder if the default price rule elements in Management Center do not meet your business needs. When your customization is complete, business users can use the new price rule element in price rules.
        Creating a properties field in Management Center
        You can enable a customizable field in the properties view for a price list in the Catalog Filter and Pricing tool. You can use the extra field to display offers and discounts for certain regions to your customers.
      - Registering custom command implementations in the command registry
        If your store uses custom commands that handle pricing terms for contracts that do not use price rules, you must register the command implementations. This is required so that you can continue to use your custom command implementations for existing contracts, and also use price rules for new or updated contracts.
      - Displaying an alternative price in Management Center
        You can customize Management Center to show an alternative price to your customers, such as a competitors price, with the Catalog Filter and Pricing tool. This price list is in addition to the list price and offer price. You can choose where to display the alternative price, on pages such as the category page, product detail page, or order flow page.
    - Customizing store preview
      You can customize store preview to add enhancements that help business users work more efficiently. These enhancements include the click-to-edit function and in-context preview function.
    - Customizing content versioning
      The content versioning feature is enabled for some objects in the Catalogs tool in Management Center. You can add or remove content versioning support for existing objects and custom objects by customizing both Management Center and WebSphere Commerce server.
    - Customizing the infrastructure component
      Customizing the infrastructure component provides you the ability to change configurable properties for Management Center and Search Engine Optimization (SEO) functionality.
    - Developing JSP pages
      To create JSP pages for WebSphere Commerce, you should have Rational Application Developer skills and JSP skills. You should also be familiar with JSTL.
    - WebSphere Commerce JSP programming best practices
      This section offers the following selection of JSP programming best practices, which promote development of reusable and easily maintainable JSP pages within the WebSphere Commerce store development framework:
    - JSP pages and data beans
      A data bean is a Java bean that is used within a JSP page to provide dynamic content. A data bean normally provides a simple representation of a WebSphere Commerce entity bean. The data bean encapsulates properties that can be retrieved from or set within the entity bean. As such, the data bean simplifies the task of incorporating dynamic data into JSP pages.
    - WebSphere Commerce useBean tag
      The useBean tag instantiates a WebSphere Commerce data bean and automatically populates it for you. A new programming direction has also been undertaken with our starter stores that now use the JavaServer Pages Standard Tag Library (JSTL) to perform view logic, instead of Java code. At the same time, business logic has been moving into data beans. The combination of these steps allows for less Java code in a JSP page.
    - Search engine optimization (SEO)
      You can use one of the following solutions to optimize your store for search engine results.
    - Double-click handling in WebSphere Commerce
      The purpose of double-click handling in WebSphere Commerce is to prevent processing the same request twice to ensure data integrity within the system. When processing certain URL requests, such as OrderItemAdd, the double-click feature of WebSphere Commerce will identify whether the request from the online shopper is currently being processed and blocks the current request if that is the case.
  - 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.
  - WebSphere Commerce development environment
    WebSphere Commerce Developer is the development toolkit for customizing a WebSphere Commerce application.
  - Web services and WebSphere Commerce
    A web service is an interface that describes a collection of operations that are accessible through the network by using standardized XML messaging.
  - WebSphere Commerce Search
    WebSphere Commerce comes with a powerful and fully integrated search function. The search functions in WebSphere Commerce provide an enriched customer experience, with features such as automatic search term suggestions and spelling correction. Since it is built on open standards, WebSphere Commerce Search is highly flexible and extensible. Starter stores can use the search engine's most sophisticated features without requiring extra customization. A key feature of Search is that sales personnel can create and manage search term associations, and search-based merchandising rules, from within the Management Center and Store view.
