METHOD FOR EXTENDING DISTRIBUTED SYSTEM APPLICATION ACCORDING TO TIERS

摘要

PURPOSE: A method for extending a distributed system application is provided to offer the independency and the extension of each tier by providing a programming pattern using a mapper, and by redefining an application under performance instead of changing the application through the mapper in case that a new object is added or a schema of a database is changed. CONSTITUTION: An interface with a user is performed through a view class(110) inherited from a view mapper(100). The view class(110) transmits the user's message to a business class(130) inherited from a logic mapper and formed. The business class(130) transmits the user's message transmitted from the view class(110) to a storing place class(150). The storing place class(150) processes the message received from the business class(130) with a transaction of a database(160). The storing place class(150) transmits the processed result to the user using the business class(130) and the view class(110).
