Abstract: In order to meet the needs of daily management of stem analysis information and improve the efficiency of internal work of stem analysis, based on the MVVM（Model-View-View Model） architecture, combined with the MongoDB database, the Express back-end framework and the Vue front-end framework, this paper designed and developed the stem analysis information management system, which was decomposed into front-end and back-end. It provided user management, information management, information query, information edit, one-click analysis of information, notification management, log management and other functions. It realized the digital management of stem analysis information and automation of internal work of stem analysis, so as to meet both the needs of information management and processing. The results showed that the stem analysis information management system had the characteristics of beautiful interface, easy to use, fast and efficient, and supports online use. The MVVM architecture can greatly improve the system development efficiency and system performance.
