Research On Data Archiving And Data Reconstruction Strategy Based On ASP Platforms Of Auto Industry Chain Collaboration

Automobile industry chain is a new organizational model which was produced in a new deal context of a new era with the fierce market competition, it was a chain of value by composing of automotive manufacturers and dealers, suppliers, service stations to the product of a technology and capital formation. Basing on ASP technology services public platform, the automotive industry chain is a public application services platform, and provides information technology services for the small hand medium-sized manufacturers of automobile. With increasing of registered enterprises, the data also shows explosive growth in database of ASP platform system, much of which has a low frequency of using and closing in the business. It has very serious impact on the system response time and corporate query efficiency, and data archiving technology can alleviate this phenomenon effectively.Basing on the ASP platform of automobile industry chain collaboration, the Physics structure of the database was analyzed. According to the data of different lifecycle in the database, data was classified into three categories. In order to reducing the burden on database of the platform, the data archiving solutions was studied in the ASP platform of the automotive industry chain collaboration, which is online business database storage and offline archiving database storage. Relational databases are adopted in online database, and archive database using the form of hierarchical structure in XML documents. The target data were migrated in different databases by data archiving and reconstruction system.Firstly, the key technologies were researched in data archiving and reconstruction system of the ASP platform. The hierarchical storage strategy of XML document structure in archiving database, mapping rules between XML documents and relational database were analyzed. The two data value models and migration strategy in data archiving system were researched. Secondly, through the analysis of data archiving system'work principle, the overall design of system functionality, each functional module and system architecture were analyzed. Thirdly, after the analyzing of original nature in data reconstruction, the critical steps of data reconstruction on the ASP platform and the platform database structure and non-structural differences before and after data reconstruction were researched. Lastly, the various modules were complied in data archiving and reconstruction system, the business logic principle was analyzed after data archiving of the ASP platform when querying data.
