Abstract: For the purpose of encapsulating application and adapting it to the Internet environment, a multi-tier application structure based on the domain model is proposed. It can improve the reusability and transplantation through applying domain object to encapsulate the core entities and business logic. The implementation algorithm and process of access control is studied on the model, and it has been applied in two real systems.
