The Design And Implementation Of Data Management System Based On XML

In recent years,the rapid development of Internet has brought great changes to human life,the network has become an important means of information dissemination and exchange.Because many data on the network are often lack of clear patterns,there are irregular forms of data,which gives a new challenge to the query and processing,and the concept of semi structured data is proposed.As XML(Markup Language Extensible)data model and semi structural data model has a lot of similarities,it can be said that XML is a semi structural data on the internet.So this paper studies the data management system based on XML,and solves the problem of data sharing and interaction from the data level.Firstly,the research status of data management system based on XML technology is studied in this paper,the main characteristics of XML data management are analyzed,and the requirement analysis of data management system is completed.According to the functional requirements of the data management system,the design and implementation of XML file data increase,delete,query,and the increase of users,delete,access control function;the design of the data transfer between and interaction function,realize the different types of data storage;the design and implementation of the data management in the process of the query and processing function as well as data encryption and security protection function;the design and implementation of different application procedures for communication functions through the way of message queue.In this paper,the data management system to achieve a different user at the same time for the same data for the operation of transaction management,focusing on the suitable for XML document management database management methods.For the security of the database,this paper also studies the security issues in the database management system and the user rights division.Finally,the corresponding tests are done for different types of data and different management users.The results show that the management system based on XML has a high availability and ease of use,can better solve the management of XML data,and also can get a good security.In this data management system,the application of XML documents in the application of the data described,through the XML technology unique performance,to achieve a good application of the general and scalability.
