18th Oracle Developers Forum




Introduction

1st presentation at 17th ODF in May 2005

After 8 months of development,3 applications have beendesigned and put in productionby IT-AIS-HR.

What is our experience?•SIR: François Briard•PRT: Nikolay Tsyganov•CTA: Camilla Stenersen

What do we think of the tool?•Pros & Cons, Roadmap: Giovanni Chierico

François Briard




SIR – Safety Information Registration

SIR allows to- Register safety courses attendance- Follow safety courses- Pass safety courses tests- Manage safety courses registrations

SIR offers two authentication modes:- AIS Login (web self training mode)- Card scan (kiosk mode)

Currently SIR proposes - Basic Safety Registration (kiosk) - LHC Machine Safety (1922 courses taken)- ATLAS Safety (1123 courses taken)

1. Automatic page designNearly all administration pages have been created using a wizard then slightly modified

2. Processes based loggingProcesses allows easy monitoring and logging of the application

3. SVG graphicsCharts are very easy to generate, but not easy to modify

Some useful features …

PRT – Pre-Registration Tool

PRT allows firm's representatives to fill electronic version of the Registration Form and provide it to Registration Office days before the actual arrival of personnel at CERN

Added to pre-registration process, PRT also allows firms’ representatives to follow up the lifecycle of their personnel at CERN

Planned to develop a “Users’ Office” PRT in 2006

1. AuthenticationIntegrates with AIS login using CUSTOM_PAGE_SENTRY PL/SQL return boolean function

2. Authorization schemeManages access rights to all components (pages, regions, items, processes).Authorization schemes are fully customizable (using SQL, PL/SQL, Item values).

3. Validation- Mandatory fields- Checks of data types- Checks of content (accented characters, etc.)- Checks for data integrity for non-mandatory fields

4. Editable and read-only items depending on conditions

5. Printer-friendly version and conditional display of components

6. Hide and show regions, icons and debug info in the region titles

Some useful features …

CTA – CERN Training Application

•Allows the users at the training department to add and edit information about courses and their participants•People use EDH to register for a course, and are added to the database as waiting registrations.•Stores information about resources (rooms) and reservations for them.•Sends e-mails to participants.

1. Custom PL/SQL regions.Regions can be created dynamically using the package UTL_HTTP which prints information on the screen.

2. E-mail sendingHTMLDB can use UTL_MAIL, which allows us to send emails from the application.

3. Functions can return queries used to generate the reports (Dynamic SQL)Code reusability issues addressed with computations

4. Request variablesWhen branching to a page, we can decide what to do based on the action used to reach the page

5. Overview of used templates, lists of values etc for each page

Some useful features…

Conclusions: Trade-off

App complexity

Effort

HTMLDB

JAVA

•Flexibility complexity

•Good for small-to-medium sized projects

•PL/SQL experienced developers

•Database driven web apps

Giovanni Chierico




Conclusions: Pros & Cons

Giovanni Chierico

-100% web based-Painless deployment-Fast lifecycle-Development interface-Quality of widgets & templates-Full PL/SQL power available-Big community

- Error handling- Debugging- Code reusability- Version control- Extension of standards components- Proprietary solution

+ -

?Life expectancy•Comes bundled with all versions of OracleDB from 10g including Express Ed.•Version 3.0 announced for end 2006 (visual layout editor, wizards, printing)•Very high quality of support (forums and direct contact)




Conclusions: Application Express 2.0

Giovanni Chierico

•SQL Workshop•New DB Object Browser•Integrated Query Builder•Utilities

•Interface•Dynamic “pull down” menus•HTML & CSS clean-up
