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.

Claims

1. A method for maintenance of engineering change data for allowing a user to maintain engineering change data via a network terminal device and a network communication system, the method comprising the steps of:

having a form generation module search electronic form data from a database according to access rights and search conditions entered from the user via the network terminal device and generate an electronic form for maintenance of engineering change data based on the searched electronic form data from the database to which electronic form the user enters the engineering change data via the network terminal device;

having a verification module compare engineering data before and after being modified by the user via the network terminal device to determine if engineering data, which are unexpected to be changed, are modified by the user;

if yes, generating an alert message to confirm this modification with the user;

having a transfer module transfer the electronic form with the engineering change data to an associated responsible unit for verification and approval after the engineering change data are confirmed and sent by the user via the network terminal device; and

having a maintenance module update and upgrade version of engineering data in the database and a backend data processing system once the engineering change data are verified and approved.

2. The method of claim 1, wherein the network terminal device is a workstation, personal computer (PC), notebook computer, palm computer, personal digital assistant (PDA), or cellular phone.

3. The method of claim 1, wherein the network communication system is Internet, Intranet, or Extranet.

4. The method of claim 1, wherein the network communication system is a cable or wireless communication system.

5. The method of claim 1, wherein the backend data processing system is an Enterprise Resource Planning (ERP) system or a Material Resource Planning (MRP) system.

6. The method of claim 1, wherein the engineering change data comprise an engineering change notification, a material list change notification, or a material change notification.

7. The method of claim 1, wherein the database is an associative database.

8. A system for maintenance of engineering change data for allowing a user to maintain engineering change data via a network terminal device and a network communication system, the maintenance system comprising:

a database for storing engineering data including at least engineering change data, material data, electronic form data, data of responsible units for verifying and approving the engineering change data;

a form generation module for searching electronic form data from the database corresponding to search conditions entered from the user via the network terminal device and for generating an electronic form for maintenance of engineering change data according to the searched electronic form data, the electronic form being displayed on the network terminal device to which electronic form the user enters engineering change data via the network terminal device;

a verification module for comparing in real time engineering data before and after being modified by the user via the network terminal device to determine if engineering data, which are unexpected to be changed, are modified by the user;

if yes, generating an alert message to confirm this modification with the user;

a transfer module for obtaining an associated responsible unit from the database according to the engineering change data entered by the user via the network terminal device and for transferring the engineering change data to the responsible unit for data verification and approval; and

a maintenance module for storing the verified and approved engineering change data in the database to be distinguished from those before being modified, and for transferring the engineering change data to a backend data processing system for data management depending on the user'"'"'s requirement.

9. The system of claim 8, wherein the network terminal device is a workstation, personal computer (PC), notebook computer, palm computer, personal digital assistant (PDA), or cellular phone.

10. The system of claim 8, wherein the network communication system is Internet, Intranet, or Extranet.

11. The system of claim 8, wherein the network communication system is a cable or wireless communication system.

12. The system of claim 8, wherein the backend data processing system is an Enterprise Resource Planning (ERP) system or a Material Resource Planning (MRP) system.

13. The system of claim 8, wherein the engineering change data comprise an engineering change notification, a material list change notification, or a material change notification.

14. The system of claim 8, wherein the database is an associative database.
