What is 'SAP'? Someone asked me about it today and I discovered that I really didn't know. I've searched the web and read various things, but nothing really explains what it is or what it does. So far all I can determine is that it's a centralized structure for all incoming and outgoing data requests. Like some sort of a huge management system that controls every piece of an organization's infrastructure whether it be faxing, email, accounting, human resources, etc. What I don't get is... Is it a software application? A DB server? A group of servers all doing thier own things but managed by something greater? Is 'it' what ever I want 'it' to be? It's like trying to define The Matrix. Any help would be appreciated.
