PHP / MySQL - highly transactional programming & thousands of concurrent users?

# Strong understanding of highly transactional programming
# Code optimization to support thousands of concurrent users

Hi,

I've just seen these included in the specs for a job advertisement for a PHP, MySQL Web Developer.  Could you give me some ideas / examples of regular solutions / patterns to solve these problems.

What is highly transactional programming? Is this just a fancy term for a web app / site that will have to do a lot of DB updates?

What are the normal methods to accommodate high numbers of concurrent users in web apps.  What can i do in the PHP / MySQL? or is it really down to Apache / MySQL Server and the hardware to deal with this?

Thanks

Thanks bportlock,

These 2 are listed as preferred skills - i have all the required skills on the job spec.  I just want to understand what the two terms meant.

Anyway, now i know what is meant by Transactional Database Updates.  Could i get a little more information about concurrent users just in terms of PHP / MySQL - i just want a very high level overview like what was given  for transactional databases above.
