隨著信息技術(shù)的高速發(fā)展，使得識別每一個客戶并提供個性化服務成為可能，美國著名的戰(zhàn)略咨詢公司 Garmer Group 正式提出完全以客戶為中心的應用系統(tǒng) — — CMS(客戶管理系統(tǒng) ) [1]。 NET platform。 (2) Accordingly, the author attempts to design the software for regionallevel customer management system, which is used by SQL server2020 for the database and based on .NET platform. The system of the multilayer architecture has user information, privileges management, customer information, contract management, sales management and maintenance functions and improves the management efficiency of enterprises。 關(guān)鍵詞： 地區(qū)級客戶管理系統(tǒng)； .NET 平臺；多層架構(gòu)； 服務器緩存 分類號： 北京交通大學專業(yè)碩士學位論文 ABSTRACT v ABSTRACT With the rapid development of China39。 實現(xiàn)了對用戶管理、權(quán)限管理、客戶常用信息、合
