Wikileaks offered but a glimmer into the hidden Web. It s a world that exists behind the firewall, yet it s essential to the operation of the world. The enterprises of today depend on the intranet (also known as the hidden Web) and all its information to run their organizations. We take for granted that today we can access enormous amounts of information and collaborate with others within our organization and on the Internet. We ll examine how Big Data and Enterprise Information Management (EIM) developed over the last 40 years and how the Web has made the demands, and the possibilities, explode. Technologies are evolving at a rapid fire rate, putting us much further ahead than we earlier anticipated. We have already advanced well beyond Web 2.0, which only just arrived as a phase in Internet development. This book traces this technological evolution from the early days to the current shift in computing and the delivery of content and services to users. Behind the firewall, where the database and application suite remain critical core components to an enterprise infrastructure, the future belongs to the combination of Customer Experience Management, Enterprise Content Management, and Business Process Management.
