1) Explain what is Microstrategy?
Microstrategy is an enterprise business intelligence application software vendor. It supports scorecards, interactive dashboards, ad hoc query, high formatted reports, etc.
2) Mention what specific features and functionality do you get with OLAP services?
With OLAP services users can create a unique report views by removing or adding attributes and metrics contained within the intelligent cube. Without submitting a new request to the data warehouse, the new calculation is performed.
3) Explain how intelligent cubes are different from ordinary cubes?
Intelligent cubes are generated automatically when a new report is run against the data warehouse. Users don’t have to mention the cube to which they want to connect. Within the Microstrategy platform, the logic to match user requests with the proper intelligent cube is automatically handled. Subsequently the requests made by other users can seamlessly hit this new intelligent cube.
4) List out the end user products that delivers OLAP Services?
End user product that delivers OLAP services includes
They all leverage the functionality enabled by OLAP services
5) Explain what is the difference between the Report filter and Report limit?
6) Explain what is Logical view in Microstrategy?
In Microstrategy, logical view is a table that you create by writing the SQL in Microstrategy instead of pulling it out from warehouse catalog.
7) Explain what is Smart Metrics in Microstrategy?
Smart metric is referred when a compound metric is defined with other metric objects using arithmetic operations like sum M1/M2.

8) Mention what types of testing can be carried out over the Microstrategy reports?
Microstrategy can carry out test like
9) Explain what is Microstrategy Narrowcast server?
Microstrategy Narrowcast Server is a software product which monitors and delivers individualized information to users through e-mails, web portals and wireless devices like pagers, PDAs, and phones. Users determine what information they want, when and how they want to receive it, through an easy to use web page.
10) Explain what are the advantages of dataset compared to file-set?
File set consists of total tables and information while data-set consists of attributes, metrics of a particular report only.
11) Explain what security does Microstrategy provides?
Microstrategy provides many security options to make sure that data is kept private and confidential. To make easy access and minimum maintenance, Microstrategy desktop synchronize with Windows NT and 2000 security and with Novell directory. Due to that users who have logged into these systems does not have to log on again.
12) Mention what is the difference between Schema object and Public object?
Schema objects are availed to create Application objects like Attributes, functions & operators, Hierarchies, Tables, etc. While, Public objects are used to create other application objects like Filters, Metrics, Consolidations, etc. Using architect permission schema object can be created while public object can be created by using a schema object only.
13) Explain what is Listeners?
Listeners allows us to view the result of samplers in the form of trees, graphs, tables or simple text in some log files. They offer visual access to the data collected by JMeter about the test cases as a sampler component of JMeter is executed.
14) Explain how you can resolve attribute roles?
By creating separate table alias for the same or enabling the automatic attribute role recognition, you can resolve the attribute roles.
15) Mention what does the predictive modeling capabilities does Microstrategy provides?
Microstrategy can calculate four of the primary data mining functions including network algorithm, regression algorithm, clustering algorithm and tree algorithm.
16) Explain how you can direct the SQL generated to use a specific table?
We can use alias name of that table and alter the logical size of that alias table dnt then modifies main table and use the alias table.
17) Explain how you can insert and update a record in the database through Microstrategy?
You can insert and update or even a delete a record by using one of the components of Microstrategy known as an ODBC test tool. You can also alter table specification as per your need.
18) Mention what is the difference between Microstrategy and Cognos?
| || |
19) Explain how you can create the intelligent cubes in Microstrategy?
20) Explain how you can optimize a report in Microstrategy?
VLDB properties enable you to customize the SQL that Microstrategy produces, and determine how data is processed by the Analytical engine.
21) Mention the process or roadmap that Microstrategy uses to query request and generate BI reports?
The process or roadmap that Microstrategy used for generating BI reports
Step 1) Connect to Database
Step 2) Create Metadata
Step 3) Create Databases ( in-memory ROLAP)
Step 4) Schedule ETL (Query Schedule)
Step 5) Create Reports and Dashboards
22) Mention different types of attributes in Microstrategy desktop?
Various types of attributes in Microstrategy desktop include,
23) Mention what is the difference between Custom group and Consolidations?
| || |
24) Mention how are Intelligent Cubes different from ordinary cubes?
Intelligent Cubes are created automatically when a new report is run against the data warehouse. Users don’t have to determine the cube to which they want to connect. The logic to match user requests with the appropriate Intelligent Cube is automatically handled within the Microstrategy platform.
25) Mention what are the business benefits of Microstrategy Narrowcast Server?
The business benefits of Microstrategy Narrowcast Server is that it provides an inexpensive way to send corporate information to untrained partners, employees, and customers. Due to which decision makers have enough information to streamline a business process that will cut the operating costs.
26) Is it possible that with Microstrategy Desktop you can join data across heterogeneous data sources?
Yes. Microstrategy 8 have extended the data modeling flexibility to include integrated views of data across heterogeneous data stores. Data can come from anywhere- data warehouse, SAP BW, data marts, and any number of operational system databases. By mapping conforming dimensions from various or different sources, Microstrategy Desktop can join data automatically from multiple unlike sources in the same report document.
27) Mention what are the algorithm supported by Microstrategy?
The algorithm supported by Microstrategy are,
28) Mention features that are not supported in Intelligent Cubes?
Features that are not supported in Intelligent Cubes are,
29) Mention the types of Report Cache?
The types of Report Cache include,
30) Mention what is an Element Cache?
An Element Cache is most recently used lookup table elements that are stored in memory on the intelligence server or MSTR desktop machines. So that it can be fetched more easily.
31) Mention whether a MicroStrategy is a MOLAP or ROLAP tool?
A MicroStrategy is a ROLAP tool.
32) Mention what is the difference between 2 tier,3 tier and 4 tier architecture in MicroStrategy?
The difference is that,
33) Mention what is heterogeneous mapping?
Heterogeneous mapping enables the engine to perform joins on unlike column names. If the user determines more than one expression for a given form, the heterogeneous mapping will automatically take place when tables and column names require it.
34) Mention what is an Implicit attribute?
An Implicit attribute has its own expression. It is a virtual or constant attribute that does not physically exist in the database because it is created at the application level.
35) Mention what are the types of fact extensions in Microstrategy?
The types of fact extensions in Microstrategy are,
36) Mention what is fact degradation?
When the fact is at a higher level than the report display level, then you can use fact degradation attribute to state how the Engine degrades the data to the lower level. When you lower the level at which a fact should be reported, you are using degradation.
37) Mention what is filtered prompt?
You can restrict the number of elements in a prompt using a filter.
38) Mention what is the difference between Report Limit and Report filter?
39) Mention what is Prompt?
The prompt is nothing but an attribute through which you can modify the contents of a report dynamically.
40) Mention different types of prompts?
Different types of prompts are,
41) Mention does it mean when you say in-memory ROLAP?
|In memory ROLAP = ROLAP Architecture + Cube Architecture.|
In-memory ROLAP is an architectural extension of ROLAP in which physical ROLAP cubes resides in-memory within the Global Virtual Cube.
42) Mention what is the advantage of using in-memory ROLAP?
The advantage of in-memory ROLAP is that it improves user wait time and free up database capacity.
