The difference between pools and archives
Your Fotoware solution gives you access to a minimum of one archive and one pool.
A pool is a physical storage container for content - for all practical purposes you can think of it as a hard drive that has a certain amount of space available for storing all your assets.
A single pool may have several archives associated with it; each archive then presents a different logical set of content that is all stored in your pool. For example, a single pool can contain several categories of pictures, but users are presented with archives that show the different categories of pictures independently.
