What Types of Triggers are Available in Report?

Report Level Triggers:

1) Before report trigger:
Fires before the report is executed but after queries are parsed and data is fetched.
2) After report trigger:
Fires after you exit the Previewer, or after report output is sent to a specified destination, such as a file, a printer, or an Oracle*Mail userid. This trigger can be used to clean up any initial processing that was done, such as deleting tables.
3) Before Parameter trigger:
Fires before the Runtime Parameter Form is displayed. Using this trigger, you can access and change the values of parameters, PL/SQL global variables, and report-level columns. 
4) After parameter trigger:
Fires after the Runtime Parameter Form is displayed. Using this trigger, you can access parameters and check their values. This trigger can also be used to change parameter values.
5) Between pages trigger:
Fires before each page of the report is formatted, except the very first page. This trigger can be used for customized page formatting.

Layout Model Triggers:
1) Format triggers

What are Format triggers?

Format triggers enable you to modify the display of objects dynamically at run time or to suppress display altogether For Headings, for repeating frames, for field, for boilerplate object To format a column based on certain criteria. 

for example
To format the max (Sal) for particular department.
To format the Sal column with a Dollar ($) prefix.

What is Data Model?
Data Model is logically group of the Report Objects through query and Data model tools. Once query is compiled report automatically generates group. The queries build the groups and then Groups are used to populate the report. The only function of queries in report is to create the groups. The Report Editor's Data Model view enables you to define and modify the data model objects for a report.
What is Layout model?
Layout Model is to physically arrange Data model group objects on the Report. The Report Editor's Layout Model view enables you to define and modify the layout model objects for a report. In this view, objects and their property settings are represented symbolically to highlight their types and relationships.
What is Previewer?
Previewer is a work area in which you can preview your report and manipulate the actual or live data at the same time. In the Previewer you can customize reports interactively, meaning that you can see the results immediately as you make each change. In order to edit your report, such as changing column size, move columns, align columns insert page numbers, edit text, change colors, change fonts set format masks, insert field the Previewer must be in Flex Mode.

What is Parameter Form?
Parameters are variables for report that users can change at runtime immediately prior to the execution of the report. You can use system parameters to specify aspects of report execution, such as the output format, printer name, mailed or number of copies. We can also create own parameters through sql or Pl/sql at runtime. When you run a report, Report Builder uses the Parameter Form view as a template for the Runtime Parameter Form. If you do not define a Runtime Parameter Form in the Parameter Form view, Report Builder displays a default Parameter Form for you at runtime.
What is Query?
The first thing in data model is the query. Through query we access database objects with sql query. Compiled query creates groups. We can create query through query builder, sql query and import query from o/s file or database.
What is Group?
Groups are created to organize the columns in your report. When you create a query, Report Builder automatically creates a group that contains the columns selected by the query. You create additional groups to produce break levels in the report, either manually or by using the Report Wizard to create a group above or group left report.

What is Repeating Frame?
Repeating frames surround all of the fields that are created for a group’s columns. Repeating frames correspond to groups in the data model. Each repeating frame must to be associated with a group of data model the repeating frame prints (is fired) once for each record of the group.
What is Flex mode and Confine mode?

Confine mode 
On: child objects cannot be moved outside their enclosing parent objects. 
Off: child objects can be moved outside their enclosing parent objects. 

Flex mode
On: parent borders stretch when child objects are moved against them. 
Off: parent borders remain fixed when child objects are moved against them.

What is Page Break?
To limit the records per page.
What is Page Protector?
The Page Protect property indicates whether to try to keep the entire object and its contents on the same logical page. Setting Page Protect to Yes means that if the contents of the object cannot fit on the current logical page, the object and all of its contents will be moved to the next logical page. Ex: if you set yes, the object information prints another page.
What is the Print Condition?
The print condition type First, All, All but first, Last, All but last refer to the frequency with which you want to appear based upon the setting of the print condition object. A print condition object of Enclosing Object is whichever object encloses the current object (could be the parent or a frame within the parent), while Anchoring Object is the parent object (unless you have explicitly anchored the object in which case it is the object to which it is anchored).
What is Print Direction?
The Print Direction property is the direction in which successive instances of the repeating frame appear.
What is Vertical and Horizental Elasticity?
The Horizontal Elasticity property is how the horizontal size of the object will change at runtime to accommodate the objects or data within it, same for vertical elasticity to vertical direction.
