2 Agenda Oracle technology latest directions overview Database How to monitor your whole environment Maintaining performance levels End to end monitoring in a three tier environment Features coming in version 11 Development tools Demo of Oracle JDeveloper How to move to JDeveloper from traditional Oracle tools Oracle Application Express Demo of APEX How to use APEX for fast lightweight web development Skill set required Summary How to select an approach When to use JDeveloper/APEX/Traditional Oracle tools

3 Technology Directions 1979 Database 2007 Character development Application Server Client/server development Web development SOA

4 Technology Directions - Database 1979 Database 2007 Significant increases in storage capacity Large object support XML support Grid computing Management tools

5 Technology Directions Application Server 2000 Internet Application Server 2007 Forms and Reports services Portal J2EE Web Services BPEL

6 Technology Directions Development Tools 1986 Development tools 2007 Character development (Forms/Reports) Client/server development (Forms/Reports) Web development Apex/JDeveloper SOA JDeveloper

7 Obsolescence SQL*Plus GUI version 2010 Client/server development (Forms/Reports) 2008 Transition from web development (Forms/Reports) to Apex/JDeveloper

8 Managing the Database Oracle Enterprise Manager is now usable Server collects comprehensive statistics OEM provides tuning advice (Automated Database Diagnostics Monitor ADDM) SQL Tuning Advisor recommends tuning techniques for SQL Troubleshooting is easier Multi tier monitoring is supported (if developers are recording the right information)

19 Application Express

20 Apex Overview Comes with the database Free with Oracle Express Edition Wizard driven development environment Entirely within the Oracle database Declarative approach rapid development Targeted at hosted small-medium systems development Oracle 10g (but can run on 9i) Metalink is written in Apex

21 Apex Architecture Apex Browser Apache mod_plsql Metadata Lightweight rapid web development HTML pages generated from meta data

41 Apex Skill Set SQL PL/SQL HTML JavaScript Easily learnt by Oracle developers with traditional skills

42 Approach Spend time creating UI Templates Start with a small internal application Use it to refine standards/ui Make the product widely available Aim to get rid of all the isolated small systems

43 JDeveloper

44 JDeveloper Java based J2EE technology Entirely more sophisticated approach Entirely more complex approach Uses an MVC architecture utilising ADF Business Component and ADF Faces Supports failover, huge scalability Oracle s direction of Fusion and EBS The successor of Forms Utilises many wizards to reduce learning curve

45 JDeveloper Demo

46 JDeveloper Skill Set SQL HTML + HTTP Request/Response Java JavaServer Faces JSF Expression Language JAAS/JAZN Security JavaScript + Some AJAX J2EE/OC4J Containers

47 Summary Select approach based on Functional requirements Organisation s technical architecture Skill set of staff Apex is good for smaller organisations with traditional skills and small/medium systems requriements JDeveloper ADF is the long term development environment JDev complexity shouldn t be shied away from introduce in a controlled fashion
