Analysis of Comprehensive Application of Data Information Logic in Subway Information Guidance System

Abstract

In recent years, the integration of subway information system has developed into a network data service platform with new service functions and broad development prospects. Its essence is the overall planning and optimization of data resources and it provides scientific solutions for improving system functions and for enterprise decision-making and management. The data information logic model is a relatively new data integration processing method. It can edit, integrate and plan independent decentralized data information resources among each other into a unified resource library, identify the data in them and create corresponding directories. The source data information is determined so as to achieve sharing in the process of data inheritance. The main advantage of the data information logic model is that the system can still be used after the upgrade and is good at mining the hidden value of the data. The middleware model is currently the most used data integration solution in enterprises. It mainly uses visual logic diagrams to extract hidden information of enterprise data in advance to help users more clearly grasp the context of data resources.
