The invention discloses a working navigation panel system based on PDM. The system comprises a PDM system and a PDM database thereof, a file volume server, a PDM external integration system, a navigation panel interface module, a navigation panel use module, and a navigation panel maintenance module. According to the invention, the service activity of an enterprise product design and development process is fused into a working navigation panel, according to the working characteristics and actual demands of different enterprises, the working navigation panel can be freely configured, a process working mode is realized through tab and panel data, the operation process of the PDM system is simplified, and the working efficiency is improved. Through the working navigation panel, the data interaction with a PDM external integration system can be realized, a new path is created for the data sharing among a PDM system, an MES system, an ERP system, a CRM system, and an OA system, the real-time update of the data among the systems is ensured, and thus the needed manpower and financial resources invested in maintaining each system by an enterprise is reduced greatly.
