WebSphere Commerce Enterprise

Business policy objects and commands

A business policy object contains policy information.

Policy ID
This is the primary key for the business policy object.
Policy type
This defines the business policy type. Price, Product Set, Payment, and Shipping are examples of policy types.
Policy name
Each business policy must have a unique name.
Store entity
The store or store group in which the business policy is deployed.
Properties
A set of default properties that can be passed to the business policy command. The commands associated with the business policy object are stored in the BusinessPolicyCmd table.
Effective period
The period for which the business policy object is effective.
Business policy command
Zero or more business policy commands that implement the business policy. A business policy command is typically invoked by a business process that can be either a task command or a controller command. For example, the getContractPrice() command gets the price for a term and condition. This price term and condition refers to a particular price policy command and this price policy command is used to calculate the price.

Multiple business policy commands can be associated with a single business policy object. Each business policy command must implement the same interface defined by the business policy type object. The structure of a new business policy command is depicted in the following diagram:

Infrastructure of a new business policy command, illustrating that you can create a new implementation class that extends the WebSphere Commerce BusinessPolicyCmdImpl implementation class, and how you can create a new interface that extends the WebSphere Commerce BusinessPolicyCmd interface.

As shown in the preceding diagram, in order to create a new business policy command, you create a new implementation class that extends the WebSphere Commerce BusinessPolicyCmdImpl implementation class. You also create a new interface that extends the BusinessPolicyCmd interface.
