Research On Architecture For Application Service Hosting Platform Based On ASP Mode

Currently, many enterprises have difficulties during information construction, which are faced with lacking of funds, information technology experts and complicated information system construction process. A new type of enterprise information technology resource operational mode-ASP (Application service provider) is introduced, the purpose of this dissertation is to research on architecture of application service hosting platform based on the mode of ASP.ASP application service platform provides application software and technical service with rental mode, it is safety and trustiness, enterprise can gained more knight service, only pay fixed rent according to protocol. ASP mode with particular advantages points out a royal road for enterprise information construction in our country.At first, evolution status of ASP and research actuality of ASP application service hosting platform are analyzed, basal theory of ASP mode is expounded. Considering service content of ASP, user commonness demand and design principle of ASP service platform, bringing in enterprise portal and enterprise application integration, universal architecture for application service hosting platform based on ASP mode is put forward. Then, the function of enterprise portal is detailed discussed, some correlative popular portal products are enumerative, the level of enterprise application integration and methods of application integration based on portal are analyzed.At last, inimitable character and four-level maturity model of application softw -are based on ASP mode are analyzed, sixty-four-dollar questions of designing ASP application software are discussed, the design of multi-tenant data architecture are deeply researched:Choice and design of multi-tenant data architecture that face wit--h big business and small and medium business are discussed respectively,design an idiographic example which supports unrestrained extendibility of data model.So the research of this dissertation is quite important for design application service hostin -g platform based ASP mode.
