  • Provide relevant information to users of another company with which the company does business (extranets)
  • Develop applications

    • Three general types:
      • Plug-ins
      • Java and JavaScript
      • ActiveX and VBScript

Using a Web-to-Database

Production Tool: ColdFusion

  • Web application server:
    • Middleware application that expands Web server functionality by linking it to a wide range of services
    • Provides consistent run-time environment for Web applications

Using a Web-to-Database

Production Tool: ColdFusion

(continued)
