| Abstract: | According to the demand of one Container Enterprise of certain Port,this paper designs a Heterogenous Database Integrate System,which can utilize the existing information resources of this enterprise as fully as possible. Firstly,this paper introduces Database Replication technology,then realizes an interface of importing data by using Static Replication technology ,and plans an interface of reahime data taking use of Dynamic Replication technology.After that, this paper introduces XML and XML-based Globe Scheme Query Language,and then designs Globe Query Mode with them.Lastly,this paper illustrates how to realize Globe Query through an example. |
