SQL is "Structured Query Language": Many computer folks still call it Sequel. That's what IBM called it when it first came out. It is a computer language that was set up to retrieve and manage information from a database. It actually is how the database for this message board works. It is also how many very large corporate databases work.
I first saw it back in the early eighties when it was nothing more than a fairly simple retrieval system for small databases. It has now grown into something that is "supposed" to be standard but, with all computer stuff, no longer is but the basic concepts remain the same on all type of SQL.
There are a number of different types of SQL. MySQL is very common for small to medium sized databases. T-SQL for transaction oriented databases. Oracle's (Big Database guys) PL/SQL for Procedural oriented databases. These names aren't necessarily associated with a specific function but more by a specific vendor. IBM, MySQL, Microsoft, Sybase or Oracle.
It looks a lot like COBOL because of it's syntax and basic commands of SELECT: GROUP: BEGIN: UPDATE: CREATE but the rest becomes fairly weird after that. There are also a lot of great tools out there so the common user doesn't have to get down to the nitty gritty to create simple to fairly complex SQL programs but you still have to know the heavy stuff if you live the life.
It's rather funny that back in the late eighties we used to think that 60,000 transactions per second was fast for a database. Now, using multiple processors and new generation databases 1,200,000 transactions can be done per second. Just think, here at Cruisemates, we could have over a million people hitting enter at the same time and not miss a beat. I don't think Paul would pay a few million dollars for that.
It's a fun new world and I am very happy that Paul's daughter is right in the middle of it!!!! Be proud Paul!
Added: Paul, I just went to Amazon and bought the book.

Congratulations Paul, and especially congratulations to your daughter. That's quite an accomplishment! I don't understand it either, but I bet I benefit from people that know all about that stuff. What proud parents you must be!
Paul sounds about his daughter's book like I always sound about my niece's education. She just got a math degree and when I would ask about her grades, I couldn't even understand the TITLES of the courses she was getting As in!
Congratulations!! What a wonderful accomplishment.
