1⟩ What are the advantages of dataset compare to fileset?
Dataset Contains attributes,metrics of the particular Report Only.
Fileset Contains total tables and information

Dataset Contains attributes,metrics of the particular Report Only.
Fileset Contains total tables and information
Yes
Open Warehouse Catelog from Architect.Select that particular
DSN.Then it will display available tables in that DSN.Select
the particular table and right click on that,select SHOW
SAMPLE DATA.then it will show sample data in that data set.
1)If in this question we want to deal with null in MSTR
report than we have some display property in report data
option which we can change according to the replacement of
null values.
DATA>>REPORT DATA OPTION>>DISPLAY>>NULL VALUES
2)if we want to deal with sql geration of report than there
is an option of VLDB property according to you requirment u
can deal with sql query of report.
Go to tables in the MSTR .,select the table which u want
to increase the logical size dbl click on the table in the
table editor at the bottom you have option Logical size
there increase logical size and check preserve logical size
when updating schema
difference between schema objects n public objects is
schema objects can be created by using architect permission
and public objects can be created in desktop and by using
schema objects only we can create public objects. schema
obj ex is attributes, facts,hierachies, transpermations
public objects ex is metrics, filters,prompts and so on.
explain the difference between documents and dashboards in mstr your self
we can create only derived metrics in document
by click insert-> new metric
Consolidations :
Consolidations are used to Specify the data you want to view in your report,and it allows you to group attribute elements in New ways without changing the metadata and warehouse definitions.
Use:
When the client want to view profit values as per season wise for a particular region, in this situation season attribute not available in data so we can create the season consolidation as SEASON = {(SUMMER = FEB+MAR+APR+MAY)+ (SPRINT = JUNE+JULY+AUGUST+SEPTEMBER) + (WINTER = OCTOBER+NOVEMBER+DECEMBER+JAN) };
The above consolidation we can insert into report then it will displays the season wise profit values.....
Intelligent Cubes can be created in microstrategy in public
objects folder or in a particular user folder. We can create
a report and point the report to a cube or right click in a
folder and click on cube option to create a new cube. once
the cube is created, choose the report objects (attributes
and metrics) which is required and save the cube. once the
cube is saved and ran to check without any errors, one can
create multiple reports out of a cube. also, you can add new
attributes and metrics when ever necessary and those will be
readily available when you run the reports next time.
Element cache:
Most recently used lookup table elements that are stored in
memory on the intelligence server or MSTR desktop machines.
So they can be retrieved more quickly.
Example:
When a user runs a Prompted report containing an attribute
element Prompt or a hierarchy prompt,an element is created...
We can create number of project sources in Metadata.
But we can access one project source at a time in Microstrategy 8x.
Apply specfic filter condition then after we can get the
report data set. it is olap. view filter main use viewing
purpose for custmoers.
we can use alias name of that table and change the logical
size of that alias table dnt modifies main table and use the
alias table..
Static prompted reports :-
when report is executed and than we saved that report than
it become static with those prompt.
it means when report executed again than it will not ask for
the promts which are present in it.
you can do so by ODBC test tool one of the component of
microstrategy through wich u can update delete or even alter
the table specification as per your need
developer should know follow things:
i)how to create public objects(metrics,filters...ect)
ii)how to create shema objects(attributes,facts)
iii)how to trouble shoot reports/dashboards
Besides these if a candidate how to write and execute system
test case is well and good :)
VLDB properties allow you to customize the SQL that
MicroStrategy generates, and determine how data is
processed by the Analytical Engine.
Eg: if you want to display top 5, 10 or 15 ranks.
1.Create a value prompt which will prompt the user to enter
the value( to display top n rankers)
2. create a filter to calculate rank and in value field
just drag and drop the prompt created above.
Prompt will be tagged to the filter and user will be
prompted during execution. Depending on the input provided
by the user top n rankers will be displayed
You can do it without using value prompt with below steps.
Create a filter on day attribute qualified on ID operator >
and set value to resolve dynamically today – last 10 days.
Standard filtering allows the report filter to affect the
metric.
Absolute filtering raises the report filter to the level of
the target, so all subcategories in the categories included
on the report are added together.
Ignore filtering disregards filtering criteria based on the
attribute in the target and its related attributes (both
parents and children).
