Business Entity or Object

• A business object is an object that represents a real-world entity such as a person, place, or
• business process.
• Business objects bring together both the characteristics and behavior of a particular entity.
• One of the primary jobs of a business object is to enforce business rules. Business rules fall
  into two broad categories:

1. Data integrity rules – This encompasses rules that enforce things such as required

fields, field lengths, ranges, and so on.

2. Domain rules – This refers to high-level business rules such as “You can’t create an

invoice for a client who is over their credit limit”.

• Business objects are created as a separate layer as a dll and will be available across UI, Business layer and Data access layer.
• Now more adv... Business objects are made available using WCF services instead of dll. so that all the projects would be same page...
