22 Imagination To Realization Application Builder April 2-5 Orlando, Florida

23 Application Builder Run Application runs the current application Share Components common elements that can display or be applied on any page within an application Attributes apply to an entire application Export/Import 23

24 Share Components Logic controls Security controls Globalization Navigation controls User interface elements File management 24

25 Attributes Standard Application Attributes Security Attributes Globalization Attributes 25

26 Export/Import Application Page Cascading Style Sheets Image Static Files Script Files Themes 26

27 Pages Page Rendering lists user interface controls and logic that is executed when the page is rendered Page Processing lists logic controls (such as computations and processes) that are evaluated and executed when the page is processed Shared Components lists common components that can display or be applied on every page within an application Attributes lists attributes that can only apply to current page 27

28 Pages Page 0 a special page where you can define elements that will appear on every page. 28

29 Session State Management Session logical construct that establishes persistence (or stateful behavior) across page views Session IDs unique identifier within Oracle HTML DB. The HTML DB engine uses this identifier (or session ID) to store and retrieve an application's working set of data (or session state) before and after each page view. 29

30 Session State Management Referencing Session State use bind variables within an application process or SQL query to reference session state of a specified item Setting Session State HTML DB engine automatically stores values typed into fields (items) in session state, when a page is submitted Clearing Session State Item Page Entire Application Current User Session 30

31 Binding Variables SQL :MY_ITEM PL/SQL V('MY_ITEM') PL/SQL NV('MY_NUMERIC_ITEM') Static text (exact) &MY_ITEM. 31

32 Substitution Strings Include a substitution string within a template using #ABC# syntax Reference page or application items using &ITEM. syntax Use built-in substitution strings to achieve a specific type of functionality 32

33 Build-in Substitution Strings APP_ID APP_IMAGES APP_PAGE_ID APP_SESSION APP_USER HOME_LINK IMAGE_PREFIX SQLERRM SYSDATE_YYYYMMDD 33

34 URL Syntax f?p=app:page:session:request:debug:clearcache: itemnames:itemvalues:printerfriendly Example f?p=600:1:&session::::item_1,item_2:1,2 34

35 Application Creation Methods From Scratch Using SQL Queries, Tables or Views Based on an Existing Model From spreadsheet 35
