Construction of campus global data system based on data middle office

Abstract

Campus informatization has entered the data technology (DT) era. In order to solve the problems of inaccurate analysis results and inadequate decision support caused by insufficient available data dimensions in various business departments of the school, we put forward a method of using data middle office technology to gather all the data on the data platform, and let the whole campus share one data technology platform and one set of data assets. Taking the construction of global data warehouse system of Sun Yat sen University as an example, we build the data middle office architecture from bottom to top, design and construct the data hierarchical system of global data, and provide services for various data analysis applications at the upper level. Data middle office of Sun Yat-sen University has formed a set of efficient and reliable data asset system and data service capability (data capitalization and asset service) through its own platform capability and continuous nourishment of data by various businesses (business digitization). When schools need to build new business analysis applications, data middle office can quickly provide data services (data servitization) and respond quickly. One of our fundamental innovations is to separate "data assets" as a basic element, and integrate the data into the business value creation process as the means of production, and continuously generate value. Practice has proved that the construction of data hierarchical data system, in the provision of data services, the efficiency of data calculation and the accuracy of calculation results can well meet the business requirements of fast and accurate access to analysis results.
