Project GoalsProject Goals

Both text and graphic data presentation.

No special software requirements on Client-side (WEB Browsers only).

Flexible architecture (distributed systems & resources ).

Hardware ArchitectureHardware Architecture 3-Tier architecture benefits:

– ClientClient• any computer running a WEB Browser ( Netscape, Internet Explorer).

– Middle-TierMiddle-Tier• To shadow database implementation details to client (tables structure etc.): Client sees physics quantities,

not ORACLE tables, columns etc.• To do not overload Oracle server with application software.

Flexible, but robust architecture (distributed systems & resources ).

ClientClient – Send HTML FORM for requesting data.– Display HTML page sent back by Middle-Tier.
