Abstract: Deep study on the Stair-Like Architecture or its modeling methods was conducted. According to the importance of economic analysis, importance and function of elements such as cost, benefit in enterprise system integration were studied. Then a three-layer framework was proposed. To describe the economic view, in which related economic elements are considered from top to down. Relative economic factors in each layer, and based on the analysis on cost and benefit with methods of Activity-Based Costing and Analytic Hierarchy Process, the modeling elements and formal descriptions of economic view were proposed, which would be the base to develop modeling and analyzing tools for the design and implement of system integration. Finally, an application was discussed to verify the methods.

Key words: system integration, architecture, economic view, modeling
