‘Database Transactions’ – I store a lot of my site content in a database. That way, if affiliate codes change, if casino metrics change, if basically anything changes… I just update the database and it will replicate to the entire site(s).
A good example:
My top 5 casino list (or Top 3 on my main site). I store all the casino metrics (for the casinos I represent) in a database and order them based upon which ones I believe are best for the particular ‘area’ of expertise my site is involved with.
When I feel a casino isn’t as good anymore, I update the order (in the database). Now I go to the site and the order is changed on all the necessary pages.
The ‘database transaction’ is the ‘querying’ of data from the database and then displaying it on the screen.
Hope that made sense.
