What is a GUID?

For those of you who don't know, a GUID (pronounced goo'id - Globally unique identifier) is a 128-bit integer that can be used to uniquely identify something. You may store users or products in your database and you want somehow uniquely identify each row in the database. A common approach is to create a autoincrementing integer, another way would be to create a GUID for your products.
