Research On The Critical Technologies Of The Satellite Project System's Information Integrated System

Depending on analyzing the information categories related to the satellite project system integration and the demands when integrating information the integration system should meet ,this dissertation constructs a general framework of the integration's information integrated system(IIIS) ,studies the critical technologies in the application of IIIS,designs and accomplishes the integration's Documents Information Integrated Software System (IDIISS). The main work of the dissertation are as follows:First ,combined with the characteristics of Project Management(PM) in the process of researching and developing satellite model ,the requirements when integrating item information between the integration's information integrated system and project management systems are analyzed ,this paper presents a method for integrating Different Systems and fulfills the researches on integrated technologies of the integration's item information.Then ,based on the high security requirements of the integration system ,this paper analyzes the insufficiencies of traditional Access Control model ,constructs an Access & Control model for the integration system ,and discusses several problems related to purview management ,such as the hierarchical power authorization and repeal the authorization of originalpurview and the maintenance and management of purview information,etc.Moreover ,the paper carries out the researches on safe access control technologies of the integration's information integrated system ;to solve the problems of insufficiencies in data backup and system recover in the whole system ,and to solve the safe problems happens when storing and managing the backup data, an integrated framework of the integration system for data backup and recover is constructed,various integrated plans are discussed ,furthermore ,the paper fulfills the design and construction of the integrated framework for documents data backup and recover.Next,after making an analysis of the demands that the whole system should meet when generate documents ,the paper studies various technologies of generating documents ,proposes a plan of generating documents and then analyzes and compares them generally, furthermore ,the paper presents how to generate the whole documents in detail.
