Project Goals

Both text and graphic data presentation.

No special software requirements on
Client-side (WEB Browsers only).

Flexible architecture (distributed systems
& resources ).

Hardware Architecture

3-Tier architecture benefits:
– Client
• any computer running a WEB Browser ( Netscape,
Internet Explorer).
– Middle-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.

Application 1:Simple data Request (2)

Client
– Send HTML FORM for requesting data.
– Display HTML page sent back by Middle-Tier.

Middle-Tier
–

–
Translate Html Form into sql queries .
Send queries to Oracle.
Get data from Oracle and format them.
Send data as an Html page to client.

Why Mathematica? (1)

Client Requirements:
– Data Presentation (for example graphics)
– Data elaboration (for example data filtering)

Database administrator requirements:
– Do not overload Oracle server with application
programs.

Why Mathematica? (2)

Client Requirements:
– graphical presentation,
– data elaboration and data filtering
are “easy” using Mathematica.

Database administrator requirements:
– Mathematica can run outside Oracle server
(Middle-Tier).

Program Developer:
– Application, i.e. Mathematica Package(s), can be
developed by client too.
