1 CERN ORACLE DEVELOPERS FORUM 5 Nov 2001 Adding Mathematica Software to an ORACLE database Roberto Terenzi CNR-IFSI & INFN CERN

2 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 20012 EXPLORER Experiment at Cern EXPLORER Building 171

3 CERN ORACLE DEVELOPERS FORUM 5 Nov 2001 Adding Mathematica Software …

4 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 20014 IGEC data at IGEC sites: Gravitational waves events: Amplitude Time Confident time interval (IGEC2000) SNR …….. Detectors data: on/off periods sensitivity ……. IGEC= International Gravitational Event Collaboration

5 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 20015 Project Goals Both text and graphic data presentation. No special software requirements on Client-side (WEB Browsers only). Flexible architecture (distributed systems & resources ).

6 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 20016 Hardware System Architecture PC's w/s's etc. (WORLD) SUN Ultra 10 (CNR-Rome) Client(s) Middle-Tier ORACLE Server CERN 0racle Server (cern Geneva) = Internet connection internet Internet

7 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 20017 Hardware Architecture 3-Tier architecture benefits: Client – 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. Flexible, but robust architecture (distributed systems & resources ).

8 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 20018 Software System Architecture WEB Browser Communication, Oracle Interface, Data elaboration & Data formatting Client Middle-Tier ORACLE Server 0racle = Internet connection SQL QUERY & DATA HTML FORMS & PAGES

10 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 200110 Application 1:Simple data Request (1) 0racle Custom Java Classes Java JDBC JDBC Methods Override post/get/service JAVA Servlet classes WEB Browser = Internet connection HTML FORMS & PAGES SQL QUERY & DATA Servletrunner

11 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 200111 Application 1:Simple data Request (2) Client Client –Send HTML FORM for requesting data. –Display HTML page sent back by Middle-Tier. 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.

12 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 200112 Why Mathematica? (1) Client Client Requirements: graphics –Data Presentation (for example graphics) data filtering –Data elaboration (for example data filtering) Database administrator requirements: Database administrator requirements: Do not overload – Do not overload Oracle server with application programs.

13 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 200113 Why Mathematica? (2) Client Client Requirements: –graphical presentation, –data elaboration and data filtering are “easy” using Mathematica. Database administrator requirements: Database administrator requirements: Mathematica can run outside Oracle server (Middle-Tier) – Mathematica can run outside Oracle server (Middle-Tier). Program Developer: Program Developer: –Application, i.e. Mathematica Package(s), can be developed by client too.

14 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 200114 Application 2:Data elaboration (1) Middle-TierSoftware 0racle SQLQUERIES DATA Mathematica DATA Graphics DATA (GIF) HTML Page(GIF) HTML FORM CLIENTMIDDLE-TIER SERVER

15 Roberto Terenzi (ROG) Cnr INFN Cern CERN ORACLE DEVELOPERS FORUM Geneva 5 Nov 200115 Application 2:Data elaboration (2) Client: – send HTML FORM to request data. Middle-Tier – translate Html Form into sql queries. –Send queries to Oracle. Mathematica –get data from Oracle and elaborate them via Mathematica program. text orGIF images –send computed data as an Html page to client (text or GIF images as needed).
