layer chart

類型

類型繼承

At the bottom is the Service layer, which includes fine-grained(細粒的; 精準的) business methods, such as the ones responsible for adding promotions to a cart, or for calculating the total value of the cart. These services expose the data model, which persists in the database.

On top of the Service layer, there are facades, which implement specific business use-cases, such as adding a product to a cart, placing an order, or searching for a product. The facades expose the Data Transfer Objects (DTOs), which are completely independent from the underlying storage technology. There may be a one-to-one mapping of the model (such as store products), but there may also be a subset of the model, or aggregated models. The DTOs are not always stored in the database. An example of this is the Solr objects, which are stored in the Solr index.

The converters delegate to populators to convert the DTOs back and forth to models. For example, a product that has basic attributes, such as name, title, and description, can also have classification attributes. Therefore, you might have two populators, one for the basic attributes, and one for the classification attributes.

The facade layer, including the DTOs, represents the SAP Commerce OmniCommerce Connect. This is a business API, and the foundation for the web services.

On the top layer, the Controllers take the DTOs and expose them to the view. This is done using the Spring Model View Controller (MVC), which replaces all the facades, services, and controllers.
