Don't forget that SQL is a second language you need to know. You can read about the basic such as SELECT, INSERT INTO, UPDATE, DELETE etc here: http://www.w3schools.com/sql/
which also has a SQL Editor to run examples or any other website can be found online.
About the script itself, 4 functions are only used (excluding the two to open/close the dabase) and in other occasions, the function to go to the next row which had no use for this tutorial. They're not a lot so it shouldn't confuse you.
Any question you have though, feel free to ask! I'd gladly try to explain it better myself.
