2) Problems we met
a. How to design the structure of various elements in the database table.
b. How to optimize the database caching mechanism.
3) The way to deal with them
a.First, all elements are put into the database, such as time, fund type, user name, fund increase, etc. First, write the first normal form, because the first normal form is too redundant, and then convert to the second normal form, and so on. After comparison test, we choose the third normal form, too much time will be wasted, and the third normal form is more moderate.the integration of the back end.
b.In order to climb the real-time valuation, the client accesses the API link, inputting the fund code to return the valuation, preventing the lag caused by excessive access. Finally, we choose not to store in the hard disk but in the memory, which can quickly read in and read out, and store various information in the memory. Can allow the customer to search directly return the data crawled within a minute, can greatly reduce the pressure on the server.
2.The record of the stand-up meeting
1) meeting content
Explore the structural design of various elements in the table of the database and discuss how to optimize the database cache.
2) meeting process

3.Sprint project introduction
1) Github
https://github.com/LittleMatcher/EE308FZ-fund
2) Screenshots of the operation
E-R model:

Model of relationship:


3) The process
The basic function of the database has been basically improved, and the speed can be relatively stable in the comparison of multiple access.
4) Burndown Chart
