This document discusses how an intranet can be used within a company to enable email communication, access databases, facilitate collaboration, and enable transactions with customers. An intranet email system allows internal communication using standard email clients. Databases can be accessed over the intranet through HTML interfaces, requiring programs like CGI or Java for searching. Collaboration is supported through groupware features for brainstorming, scheduling meetings, co-authoring documents, and sharing databases. Corporations can also use intranets to enable secure online ordering and payments by customers through a firewall and encryption technology.
