Office SharePoint Server 2007 provides a single integrated platform to manage intranet, extranet, and Internet applications across the enterprise.

• Business users gain greater control over the storage, security, distribution, and management of their electronic content, with tools that are easy to use and tightly integrated into familiar, everyday applications.
• Organizations can accelerate shared business processes with customers and partners across organizational boundaries using InfoPath Forms Services–driven solutions.
• Information workers can find information and people efficiently and easily through the facilitated information-sharing functionality and simplified content publishing. In addition, access to back-end data is achieved easily through a browser, and views into this data can be personalized.
•  Administrators have powerful tools at their fingertips that ease deployment, management, and system administration, so they can spend more time on strategic tasks.
•  Developers have a rich platform to build a new class of applications, called Office Business Applications, that combine powerful developer functionality with the flexibility and ease of deployment of Office SharePoint Server 2007.
