Data Manipulation Framework Of Distributed System Base On .Net Framework

The data manipulation is the basis of information management system. With the development of computer software and hardware and the fast development of computer network, the requirement of enterprise and workingarea for informatization management is continuously increased. As a result, the software-exploiture must be faced with huge load, such as repeated exploiture and the low repetition rate of code and so on. But in the numerous information management systems, there must exist certain comparability in data manipulation. So, in this paper, 'General Data Manipulation Framework of distributed system Base On .Net Framework' is studied emphatically and realized partially.In this paper, the study is combined with the exploiture of 'The system for emergency handling of abrupt affairs in the public hygiene of the Gansu province'. According to the physical demand, a distributed architecture with N layers for 'The system for emergency handling of abrupt affairs in the public hygiene of the Gansu province' is set up, which uses .NET framework as platform and 'Web Services' technology. In order to improve the exploiture efficiency and the maintainability of software 'Data Manipulation Framework' is deployed reasonably to the distributed architecture with N layers. The study on the data manipulation framework is the keystone. A new research direction about the maneuverability and maintainability during the exploiture of software is inaugurated, which is outstanding in the exploiture of Management Information System.This system performs such function as the release, the search, the analysis and the report of the information about epidemic situation. It is able to realize the exchange of information of the Gansu province public hygiene of the abrupt affairs fleetly, well and truly, safely and reliably. It also realizes the information support for prediction analysis and management decision of epidemic situation in our province roundly and provides powerful maintenance logistics for the establishment of policy and rationalization of management.
