Application Research On Data Integration Of Heterogeneous Database For Teaching Platform

With the Digital Campus evolves, all departments have been imported into avariety of applications. On the one hand, due to inter-independent, to build a unifiedsystem of planning and lack of standards, resulting in the application of the existingsystem is fragmented, heterogeneous, closed system, said data in different systems,poor data exchange effects, formed a month "information islands." On the other hand,due to various hardware platforms where the school was basically completed and putinto use, the system is running. Therefore, the full use of existing resources, how toimplement data synchronization between the various systems into a digital campusimportant.This school currently selected network teaching platform using the Moodleplatform with the Campus Card as a typical, data docking between the two systems toachieve the synchronization of heterogeneous databases. Network teaching platform,which uses Mysql database backend and card using oracle database platform.The main achievement of this program students will oralce basic informationtable within the database changes into an XML document, stored in the card platformserver, and then through the router to forward to the fourth floor of the roomthree-layer switch switch and the fifth floor, the final transmission to the Moodleplatform server, Mysql and then update their records the basic information table.
