The activity of the firm involves the flow of numerous amounts of information. Making use of it is often difficult because they are collected and stored in different places or in different forms. A portion of them is accessible through specially dedicated applications installed on personal computers, whereas some are in the form of printed materials or in an employee’s memory.

All sources are made available in a defined range for employees of a firm at different levels, clients, contractors and partners. It is known, that for each these groups the firm may make available an individually dedicated source. Then, special mechanisms enabling making available of chosen data and the flow of exchange of information are implemented.

A corporate portal is a way for:

• integration of chosen sources of a firm that are in different applications
• communication among users on different levels, different range and form
• connection of Internet functions, Extranet and WWW service
• making available and collecting of information
• independent management of contents

The complexity of the function of a portal demonstrates a wide range of communicative needs in an enterprise. To streamline the flow of information, companies have a corporate portal at their disposal. A corporate portal is, on one hand, available contents and tools, but also as an interface for an existing firm and its external applications.
