Due to the large amount of data generated by the system, the business topics involved are also complicated. To improve the pertinence of system backup and recovery, the Administrator hopes to provide traditional backup and recovery methods, you can also independently back up and re

after three sprint processes, deepened the understanding of the software development process, but also familiar with the use of GitHub tools, the last upload code using the form of code, the change of way, the use of the desktop version of the computer, very convenient, but also very fast, Students who are unfamiliar with the GitHub upload Code command are also encouraged to try it. In addition, through our team of each member of the reasonable allocation of work tasks, the order of the Food app
