Putting It All Together eStoreUSA built its business on a three-tiered infrastructure, with Windows NT Server 4.0 serving as the engine. Windows NT Server's integrated Internet Information Server Web server technology sits in the middle and combines the search, content, and hosting services eStoreUSA provides. The robust security features of Windows NT Server and Internet Information Server also help ensure eStoreUSA's clients that their data will remain secure. On the backend, SQL Server 7.0 stores and analyzes data for each of eStoreUSA's client sites. The relational database server allows the company's clients to run queries and analyze each store's inventory using a Microsoft Excel or Microsoft Access-based Web interface.
Clients can also download the data into their own accounting programs.
On the front end, Site Server 3.0 Commerce Edition makes it easy for eStoreUSA customers to build their own Web sites, using eStoreUSA templates. Clients can also use the Microsoft FrontPage 98 Web site creation and management application to choose colors and themes. Two servers run SQL Server 7.0. Two others run Site Server 3.0Commerce Edition. As it grows, eStoreUSA can add more servers to accommodate its longer list of clients.
