6. CERN – European Organization for Nuclear Research Administrative Information Services Demonstration of 3 HTMLDB-based applications 6 IT-AIS-HRMarch 17 th 2006 1.Authentication Integrates with AIS login using CUSTOM_PAGE_SENTRY PL/SQL return boolean function 2.Authorization scheme Manages 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 … Nikolay Tsyganov

7. CERN – European Organization for Nuclear Research Administrative Information Services Demonstration of 3 HTMLDB-based applications 7 IT-AIS-HRMarch 17 th 2006 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. EDH Camilla Stenersen Courses: 2645 Sessions: 3060 Regs: 37208 Courses: 2645 Sessions: 3060 Regs: 37208

8. CERN – European Organization for Nuclear Research Administrative Information Services Demonstration of 3 HTMLDB-based applications 8 IT-AIS-HRMarch 17 th 2006 1.Custom PL/SQL regions. Regions can be created dynamically using the package UTL_HTTP which prints information on the screen. 2.E-mail sending HTMLDB 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 variables When 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… Camilla Stenersen
