1) What are the types of layouts in reports?1) There are 8-default layout styles provided.

a) Tabular - It is the most basic type of report where each column corresponds

to a column selected from the database.

b) Form-lie - It is a report one record per pa!e. The "eld values are placed tothe "eld labels.

c) #ailin! $abel - % mailin! label report prints mailin! labels in multiplecolumn on each pa!e. The printin! can be a landscape or a portrait.

d) Form $etter - % Form letter report contains database values embedded intoany te&t that is entered or imported into the report editor.

h) 'roup $eft - % !roup left report divides the rows of a table into sets( based

on a common value in one of the columns. This style is used to restrict acolumn from repeatin! the same value several times while values of relatedcolumns chan!e.

!) 'roup %bove - % !roup above report contains two or more !roups of data.For every value of the master !roup( the related values of the detail !roups)are fetched from the database.

h) #atri& - % matri& cross tab) report contain one row of tables( one columnof labels and information in a !rid format that is related to the row andcolumn labels.% distin!uished feature of matri& report is that the number of columns is notnown until the data is fetched from the database. To create a matri& report(at least four !roups are re*uired. +ne !roup must be a cross-product !roup(two of the !roups must be within the cross-product !roup to furnish thelabels( and at least one !roup must provide the information to "ll the cells the!roups can provide to a sin!le *uery or to multiple *ueries.

i) #atri& with 'roup, % matri& with !roup report is a !roup above report witha separate matri& for each value of the master !roup.

) What are the dierent layout ob/ects? There are 0 types of layout ob/ects.a) epeatin! Frames.b) Frames.c) Fields.d) 2oilerplate.

a) Frames, Frames surrounds other layout ob/ects( enablin! control ofmultiple ob/ects

simultaneously( ensurin! that they maintain their positions relative to eachother in the report .% frame mi!ht be used to surround all ob/ects owned by a!roup( to surround column labels.

b) epeatin! Frames, epeatin! frames act as placeholder for !roupsrepeatin! values) and present rows of data retrieved from the database.

epeatin! frames repeat as often as the number of rows retrieved.

c) Fields, Fields act as placeholder for column values. They de"ne theformattin! attributes for all columns displayed in the report. % "eld is one ofthe ob/ects that can be located inside a frame or repeatin! frame.

d) 2oilerplate, 2oilerplate consists of te&t and !raphics that appear in a reporteach time it is run3 e.!.( a label appearin! above a column of data isboilerplate te&t. 'raphics drawn in the layout as well as te&t added to thelayout are boilerplate.

4) What is data model?

To specify the data for the report( a data model should be de"ned. % datamodel is composed of some or all of the followin! data de"nition ob/ects.

a) 5ueries - 5ueries are %67I-standard 75$ 7$9T statements that fetchdata from a standard database such as +racle( :2 etc. These 7$9Tstatements are "red each time the report is run. ;ou can select any numberof *ueries to select data from any number of tables.

b) 'roups - 'roups determine the hierarchy of data appearin! in the report(and are primarily used to create breas in the report. +racle reportautomatically creates a !roup for each *uery( but you are not limited to thisdefault. ;ou can create a new !roup in the data model and included a columnthat you want to use as the brea column.

c) 9olumn - 9olumn contain the data values for a report. :efault reportcolumns( correspondin! to the table columns included in each *uery

There are two ways to reference parameters in a *uery,R Ese a bind reference.

R Ese a le&ical reference.
