The Design of University Staff Data Management System Based on MBSE

This paper introduces the application of Model-Based Systems Engineering (MBSE) methodology in the normal conceptual design stage of data management system. With the university personnel data management system as an example, it establishes the model diagram on Rhapsody platform through Systems Modeling Language (SysML), and defines the forward design process of the key functional architecture of MBSE. From the system top-level model building to the user fuzzy demand acquisition, finally, taking data audit as an example, the activity diagram and sequence diagram models are built, which provide direct reference for software development. Because of the replacement of text description by models, this methodology realizes the full decoupling of system functions, ensuring a consistent understanding of system description by all stakeholders and accordingly the effective reduction of the system iterative cost.
