Development And Design Of Data Synchronization System For Hospital Heterogeneous Database

Each business system is generally build step by step due to the long work cycle of the hospital information construction,Therefore,the software manufacturers of each system,the technologies,the databases they used are different.The operation systems are independent of each other.But the hospital operation is a whole,with a lot of basic data,such as employer information,department information,etc.The public information is involved in all systems.So,we must maintain the public information repeatedly in various systems.This wastes a lot of manpower and material resources,and cannot guarantee the timeliness of the update,resulting in inconsistent data of each system.This paper proposes a solution to this problem,which is to develop a heterogeneous database synchronization update software.Use database triggers to capture data changes and record changes to a table,using jdom technique at the same time,will need to synchronize data to generate an XML document,the XML document as the intermediate data carrier,changes in a timely manner of a database synchronization to other databases,so as to better solve the above problems.In this paper,the design ideas and implementation process of the software are discussed in detail.
