Abstract
A method and a system for maintenance of engineering change data are provided. A form generation module generates an electronic form for maintenance of engineering change data according to access rights and search conditions input from a user via a terminal device. A verification module compares engineering data before and after being modified by the user to determine if engineering data, unexpected to be changed, are modified by the user; if yes, the verification module generates an alert message to confirm this modification with the user. A transfer module transfers the electronic form with the engineering change data to an associated responsible unit for verification and approval. A maintenance module updates and upgrades version of engineering data in a database and a backend data processing system once the engineering change data are verified and approved. By the above method and system, operational errors and invalid data modification are eliminated.
