Enterprise Content Management

A more recent term describing newer applications that feature both Web content management and document management. In other words, ECM systems mangle all of the content within an enterprise, usually using some type of central repository. The goal is better control of assets, such as logos or ext for a company brochure, by keeping them in one place where various departments can get to them. WebReference published an article that explains the concept of ECM in more detail: http://www.webreference.com/internet/enterprise/index.html.

Extranet

An extension of an institution's intranet, especially over the World Wide Web, enabling communication between the institution and people it deals with, often by providing limited access to its intranet.

The extension of a company's intranet out onto the Internet, e.g. to allow selected customers, suppliers and mobile workers to access the company's private data and applications via the World-Wide Web. This is in contrast to, and usually in addition to, the company's public web site which is accessible to everyone. The difference can be somewhat blurred but generally an extranet implies real-time access through a firewall of some kind.

Such facilities require very careful attention to security but are becoming an increasingly important means of delivering services and communicating efficiently.
