I have no idea, I don't see any connection between the two files ?

I have php website using mysql database and i want to using an open source program(using php+mysql)

so i want to insert my data to this open source

can help???

What is the relationship between the two structures. How does the first one convert to the second one?
Not in code, but in logical terms?
