HCL Commerce is a high-availability, highly scalable and customizable e-commerce platform. Able to support hundreds of thousands of transactions per day, HCL Commerce allows you to do business with consumers (B2C) or directly with businesses (B2B). HCL Commerce uses cloud friendly technology to make deployment and operation both easy and efficient. It provides easy-to-use tools for business users to centrally manage a cross-channel strategy. Business users can create and manage precision marketing campaigns, promotions, catalog, and merchandising across all sales channels. Business users can also use AI enabled content management capabilities.
Reference
Topics in the Reference section contain all of the HCL Commerce reference documentation.
HCL Commerce database schema
The HCL Commerce database model was designed for data integrity and optimal performance. HCL Commerce provides several hundred tables that store HCL Commerce instance data. To maintain data integrity, and to ease maintenance referential integrity, constraints are widely used in the database model. Indexes are used carefully on tables to avoid over-indexing and to provide a good balance between data retrieval and data manipulation activities (insert and update). The business rules are implemented at the application level rather than by using database trigger. Triggers, however, are used to facilitate data staging and optimistic locking. A limited number of SQL-based database stored procedures are used for data intensive activities.

When a trigger occurs, the activity flow can continue from where the trigger was defined in the flow. A target is used to qualify customers for subsequent actions or continue execution of the activity flow. Targets are usually based on a customer's behavior and segmentation. An action is a step to perform as part of the activity flow. Actions are the "to do" based on the previous sequence of triggers and targets. Most actions are for marketing purposes, such as display content in an e-marketing spot, or send the customer an e-mail.

This works in conjunction with the explicit inclusion and exclusion rules that are specified in the MBRGRPMBR table and the implicit inclusion rules that are specified in the MBRGRPCOND table. If both multiple criteria are specified, the following algorithm is used to evaluate if a member belongs to a member group: Explicit exclusion by member ID takes first precedence, then explicit inclusion by member ID, then inclusion by personalization ID, and then finally implicit inclusion.

  - Payments subsystem

  - Dynamic caching
    In general, caching improves response time and reduces system load. Caching techniques are used to improve the performance of World Wide Web Internet applications. Most techniques cache static content (content that rarely changes) such as graphic and text files. However, many websites serve dynamic content, containing personalized information or data that changes more frequently. Caching dynamic content requires more sophisticated caching techniques, such as those provided by the WebSphere Application Server dynamic cache, a built-in service for caching and serving dynamic content.
  - HCL Commerce store pages properties
  - Cache-entry elements
    The root element of the cachespec.xml file, <cache>, contains <cache-entry> elements. The WebSphere dynamic cache service parses the cachespec.xml file during start-up, and extracts a set of configuration parameters from each <cache-entry> element.
  - Data Load utility configuration file schema
    The Data Load utility contains several configuration files. You can use the configuration file schema to understand and customize the data load configuration files.
  - HCL Commerce web services
    HCL Commerce provides many web services.
  - Utilities
    In HCL Commerce utilities are scripts that perform operations such as loading access control policies, loading store data, and cleaning the database of obsolete objects. In runtime environments, run utilities from the Utility server Docker container. In the development environment, run utilities from the bin directory.
  - Shopping flow URLs
    HCL Commerce shopping flow URLs are organized by subsystem.
  - Messaging system URLs
    The following URLs relate to the Messaging system.
  - Scheduler URLs
    The server subsystem consists of functions that are associated with URLs that are run by the scheduler.
  - jQuery Enhancements API
    The Aurora starter store in HCL Commerce is completely written in jQuery, which is one of the most commonly used JavaScript libraries used in dynamic websites. The jQuery AJAX and events API provides an easy to use framework that meets most AJAX requirements for storefront development.
  - HCL Commerce foundation tag library
    The HCL Commerce foundation JSTL tag library is a collection of custom tags that are provided to you to support the authoring of HCL Commerce JSP files. HCL Commerce stores use the JavaServer Pages Standard Tag Library (JSTL) to perform logic, instead of Java code. At the same time, business logic is moved into data beans. The combination of these steps allows for less Java code in a JSP page.
