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.

Abstract: A method and a system for integration of engineering change data are provided. A form generation module searches engineering change data from a database according to search conditions entered by a user via a terminal device and generates accordingly generates an electronic form to which the user modifies the engineering change data. A modification module modifies data of an associated engineering change order with the modified engineering change data. Then, a searching module searches associated engineering change data file from the database according to the search conditions entered by the user. By the above data integration method and system, all related engineering data may be changed in response to modification of any particular engineering data by the user, and associated engineering data can also be searched during the process of searching particular engineering change data.

Abstract: A method and a system for processing engineer-designed data are provided. A data receiving/transmitting module receives engineer-designed data from an engineer design department upon receiving a data receiving request from a user through a network terminal device via a network communication system. Then, a data comparison module compares the received engineer-designed data with associated engineer-designed data stored in a database to obtain consistent engineer-designed data. A file producing module transforms the consistent engineer-designed data into a document file in a specific format. The data receiving/transmitting module transmits the transformed document file to an engineer unit corresponding to an engineering stage where the document file is formed. Finally, a data storage module stores the document file confirmed by the engineer unit in the database.
