1.Project problem summary

(1)Expected task
Construction of servers
Due to various factors such as inadequate technology and scheduling during alpha testing, the website is still unable to run on the backend server and can only achieve partial functionality in both the front-end and back-end. Therefore, in the upcoming beta sprint phase, our team needs to implement server construction. After many considerations, we considered using pagoda panel to build the server.
Improvement of website interface aesthetics
The layout of our courseware upload interface is very different from that of the main page, and the layout of the question and answer part is very different from that of the main page, which makes our switching between plates a little unnatural. We need to coordinate the styles between various plates to make the whole look more coordinated and more formal.
Back-end database access
In this development cycle, we successfully access the database, and completed the courseware upload and question answer part of the access, which makes the uploaded files can be permanently stored in the website, no longer empty after exiting the website as before. This is undoubtedly a major step forward.
Supplement to question section
In the question question, there was a bug that could not be sent out correctly in our previous question question. After this modification, we can send out the question smoothly and wait for other users to solve it.
(2)Completed task
Improvement of website interface aesthetics
We added some instructive images by scrolling through the images to guide new users through the forum.
Back-end database access
Supplement to question section

(3)The problem that hasn't been solved
However, in this development cycle, our server docking stage is at a standstill, during the development process, we can not smoothly import the code in our website, the main problem is that the domain name can not be smoothly created, its price is too high and the personal information is unknown at the time of creation. However, in this development cycle, our server docking stage is at a standstill, during the development process, we can not smoothly import the code in our website, the main problem is that the domain name can not be smoothly created, its price is too high and the personal information is unknown at the time of creation. So this is holding us up when we import the server
