This chapter describes the software platform requirements for the Siebel Business Applications clients and includes the following topics:

• Deployment Modes for Applications
• Supported Deployment Modes by Application Categorization
• Requirements for High Interactivity Clients (Employee Applications)
• Requirements for Standard Interactivity Clients (Customer and Partner Portal)

Required software includes the products that must be installed separately by the user on the client machine in order to achieve basic Siebel functionality. Siebel applications can be deployed in two modes—in standard interactivity mode or in high interactivity mode.
