  - 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
    HCL 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.
  - Creating your custom store
    After you install and set up your programming environment, you can create your custom store and customize your storefront. You must ensure that the store server is properly configured, and that your store assets are moved to the Store server.
  - Presentation layer
    HCL 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. HCL 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 HCL Commerce, you need to determine the business model supported by HCL Commerce that best represents the purpose of your site. Usually sites created with HCL 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 Transaction 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 HCL Commerce
    You can extend the HCL 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 HCL Commerce Developer to take tutorials that guide you step-by-step through various customization scenarios.
  - Run Engine command framework
    The Run Engine command framework provides predefined commands, that you can use to change environment parameters or container configurations. This framework is built into the HCL provided Docker images.
  - GraphQL for HCL Commerce
    The GraphQL markup language is available for any API. It is a server-side interpreter for processing queries using a data type system you design. With GraphQL, your data and code are independent of any database or storage system.
  - Representational State Transfer (REST) services

    - Creating and customizing REST services
      You can create and customize your own REST services with HCL Commerce Developer.
    - Working with REST services
      You can work with existing REST services to meet your business needs.
      - REST services in storefront JSP files
        REST services in storefront JSP files and site widgets use the wcf:rest tag to consume resources. This tag facilitates JSON support to reduce dependency on Service Data Objects (SDOs).
        REST services in storefront JSP files for remote stores
        Remote stores communicate with the Transaction server by using the REST services. Therefore, some JSP in V8 local store will not work on V9 remote store. Hence Java code and Data beans cannot be used. Instead you must use the wcf:rest tag.
      - Mapping REST resources to Business Object Document (BOD) nouns
        REST services are built on top of OAGIS services. Each REST resource is mapped to a Business Object Document (BOD) noun. An XML configuration file is provided to transform between a BOD noun and REST data. The REST services framework then uses this configuration file to generate REST response data from a BOD object and construct a BOD object from REST request data.
      - REST response formats
        REST services support JSON and XML formats for input and output data by default. The default format is JSON.
      - Customizing the catalog entry details page to retrieve specific merchandising associations
        You can customize the catalog entry details page for a catalog entry type to use merchandising association enhancements to the productViewHandler REST service and the categoryNavigationView noun. By customizing your catalog entry details pages to use the enhanced REST service, you can define the specific merchandising association types that return for each type of catalog entry. By default all merchandising associations that are associated with a catalog entry are displayed when a shopper views the catalog entry details for a catalog entry.
      - Customizing REST services to support new custom response formats
        You can extend the default JAX-RS resource handlers to customize REST services to support new custom response formats.
      - Configuring Cross-Origin Resource Sharing (CORS) headers
        HCL Commerce supports Cross-Origin Resource Sharing (CORS). The HttpSecurityFilter servlet filter supports the configuration of CORS-related headers included in the HTTP response. You can configure the filter by extending the component configuration file (wc-component.xml).

REST services in storefront JSP files

REST services in storefront JSP files and site widgets use the wcf:rest tag to consume resources. This tag facilitates JSON support to reduce dependency on Service Data Objects (SDOs).

Storefront REST tags

The wcf:rest tag is used in the storefront to send REST requests.

This JSP tag takes input and sends out REST requests, and then composes responses in a specified format. A REST tag, which is defined as a template, does not send out REST requests but persist its parameters in memory as default input. Then, it provides a mechanism that can reuse the template without identifying all parameters, only the modified ones. This approach is similar to the expressionBuilder in the wcf:getData tag REST access profile. A parameter is passed in to the REST tag to determine the server calculation and how much detailed data is being queried for the resource. It supports two format types. One format type is the same as the traditional access profile and search profile in a web service, a meaningful string that indicates only the querying details. the other format type is a detailed one, which identifies all required fields of the resource.

For more information, see Tag: rest.

JSON support in JSP file tags

In addition to SDOs, the responsive Aurora starter store supports fetching JSON objects, reducing the dependencies on SDOs fetched elsewhere on the JSP files.

The following tags are updated to support JSON objects:
