Definitely Stu. If you don’t know what the data is that you are looking at, you can’t make any accurate conclusions about what that data tells you. This is even more important when you start pulling data out using SQL queries – the query may work (as in return you data) but if you haven’t understood the data structure well enough to write an accurate query, the data you have returned may not actually be the data you were after.

I run a course occasionally looking at SQL queries for Moodle.
Understanding the database tables in Moodle, and the data types is absolutely vital – and this post is a great introduction to this, including the not so obvious “what looks like a number may be text” and “what looks like text might be a number” considerations 🙂
