This document summarizes an Oracle database expert's presentation on optimal use of Oracle Database 10g and 11g for modern application development. Some key points covered include how modern applications are distributed, global, and service-oriented; how new Oracle database features support cloud computing, analytics, and internationalization; and guidelines for developing applications that leverage the database while maintaining independence.

1. Optimal Use of Oracle Database 10g and Oracle Database 11g for Modern Application Development Lucas Jellema AMIS, The Netherlands Oracle Open World, San Francisco September 2008

2. What is Modern ? SOA (operational) Analytics event XML SAAS S-Ox/Audit Service MultiMedia Tera Byte 24/7 Global Asynchronous Fuzzy I18n (internationalization) Business Rules Data Integrity Share/Collaboration Enterprise 2.0 Message OO Decoupling Security Personalization Scalability B2B

10. Typical Architecture J(2)EE Application Server Batch Batch Batch Client Enterprise Service Bus DWH ?

20. SAAS – MultiOrg - Authorization J(2)EE Application Server A B C Customer C Customer B Customer C setClientIdentifier ORG USER Web Application blindly queries a table for ‘all’ records Based on User Identifier, (in current context) determine Organization Only return records associated with that organization

25. Scoring on Salary

26. Scoring on Hiredate

29. Using the number_range_score function

32. Collecting Employee’s score per criteria

33. Slightly nicer layout

34. Search results – top scoring employees

36. Fuzzy Search outcome with 3 criteria - Salary close to 1500 and within 1000-2000 - Hiredate 1982 (or less desirable) 1983 - Job is CLERK, or ANALYST or SALESMAN

38. RSS feeds are used to publish “events”

40. The browser in your database Introducing UTL_HTTP ≈ select utl_http.request ( 'http://technology.amis.nl/blog/?feed=rss2' , null ) from dual

41. Whatever the browser recives from a URL, the UTL_HTTP receives too

42. Example UTL_HTTP code: processing response SET serveroutput ON SIZE 40000 DECLARE pieces utl_http.html_pieces; n number default 0; resp utl_http.resp; BEGIN pieces := utl_http.request_pieces ( url => 'www.someurl.com' , max_pieces => 9999 , proxy => null ); for i in 1..pieces.count loop loop exit when pieces(i) is null; dbms_output.put_line(substr(pieces(i),1,255)); pieces(i):= substr(pieces(i),256); END LOOP; end loop; END;

44. Publish RSS as “view” inside database create view AMIS_WEBLOG_FEED as select title , link , author , to_date(substr(publication_date,6,20) ,'dd mon yyyy hh24:mi:ss') timest from xmltable ( XMLNAMESPACES('http://purl.org/dc/elements/1.1/' AS &quot;dc&quot;) , 'for $i in //item return <Article>{$i/title}{$i/dc:creator} {$i/pubDate}{$i/link} </Article> ' passing httpuritype('http://technology.amis.nl/blog/?feed=rss2').getXML() COLUMNS title varchar2(100) path 'title' , link varchar2(100) path 'link' , author varchar2(100) path 'dc:creator' , publication_date varchar2(100) path 'pubDate' )

45. Publish RSS as “view” inside database create view AMIS_WEBLOG_FEED as select title , link , author , to_date(substr(publication_date,6,20) ,'dd mon yyyy hh24:mi:ss') timest from xmltable ( XMLNAMESPACES('http://purl.org/dc/elements/1.1/' AS &quot;dc&quot;) , 'for $i in //item return <Article>{$i/title}{$i/dc:creator} {$i/pubDate}{$i/link} </Article> ' passing httpuritype('http://technology.amis.nl/blog/?feed=rss2').getXML() COLUMNS title varchar2(100) path 'title' , link varchar2(100) path 'link' , author varchar2(100) path 'dc:creator' , publication_date varchar2(100) path 'pubDate' )

56. Example of Employee Versions

59. Pull EMP change overview from browser

62. Create XML Resource DECLARE CURSOR xmlcur IS SELECT xmlelement(&quot;EMPHISTORY&quot;, ... l_xml_dir VARCHAR2(30) := '/public/hrmData'; l_doc_name VARCHAR2(30) := 'EmpChangeHistory.xml'; l_emp xmltype; l_res boolean BEGIN IF dbms_xdb.CreateFolder(l_xml_dir) THEN ... some ACL setting up END IF; open xmlcur; fetch xmlcur into l_emp; close xmlcur; l_res := dbms_xdb.createResource ( abspath=> l_xml_dir||l_doc_name , data=> l_emp ); COMMIT; end;

63. HRM Report via WEBDAV, SQL & HTTP

64. Viewing&Editing XDB Resource in Excel

65. Uploading data from file to database
