PowerDesigner cracked software and Chinese package can go to the official account [Sanqiao Jun] to reply [PD] to receive.
4. Experimental results
(1) Conceptual structure design
(2) Logical structure design
(3) Physical structure design
(4) SQL statement generation in database mode
The source code of the structural design and the database source code of the supply management system can be obtained from the public account [Sanqiao Jun] and reply [Database Experiment 4].
It is not easy to organize articles. If you have any help, please like and follow and support, thank you! Wechat search for [Mr. Sanqiao ] and reply [Follow] with a resource package prepared by me. Continued updates~~~
