When you need to do some "things", you create a class. But what type of class it is depends on what this class directly inherits in PRPC.

If you want the class to represent a Data Model, you create a class that directly inherit the "Data-" parent class, so this becomes a "Data Class". It's job is to be a data model for whatever data you want to represent in PRPC. Usually a Data Class is not instantiated, and it is used more as a template in the Work Class for containing data that is pertinent to the work to be resolved.

If you want the class to perform some work or some case, then you will need to directly inherit the "Work" class as a parent. This makes the class you are creating a "Work Class". It's job is to be instantiated as a Work Object or a Case Object to contain data related to the work it is doing.

Basically, the difference is what they do. In summary, a Data Class is a template for Data Model, and a Work Class represent a work type or case type for instantiating and resolving work.

Hello Chuat.

Very thanks for your information. Way of explaining awsome.

As per my understand

1)Data class will define the data model(like interface in java,implementaion won't be there in interfce but we can reuse this interface where ever we want by implementing the interface)

2) we can create the object for work class(like concrete class in java), we can use any where we want right?

Please correct if i am wrong.

Work Class - Contains the rules that describe how to process a case, such as processed, date element and user interfaces.

Data Class - Contains the rules that describe the data objects used in application, such as a customer or collection of order items.
