                           Microstrategy                                     Cognos

Microstrategy is primarily based on single meta-statistics repository

Microstrategy may be operated as net based and a computer tool

There is not any dice data-set for Microstrategy, and we reap cutting-edge statistics-set from statistics-warehouse robotically

Microstrategy reporting is fast

 Cognos has two meta-statistics repository based totally database

It can be used as web-base reporting gear

Cognos has a cube dataset which wishes to be refreshed so that it will get contemporary repository values before reporting

Compare to Microstrategy, Cognos reporting is slow

Q19. Explain how you can create the sensible cubes in Microstrategy?

Ans:

Intelligent cubes may be made in Microstrategy inside the public folder or a specific person folder

We can make a document and point the record to a dice or right click in a folder and pick the cube choice to make a brand new dice

Once the cube is created, pick out the record items that's required and save the dice

Once the cube is saved and ran to check, you can create more than one reviews out of a cube

You also can add new attributes and metrics, every time important, and those can be effectively to be had when you run the reports subsequent time

Q20. Explain how you may optimize a record in Microstrategy?

Ans: VLDB properties enable you to customize the SQL that Microstrategy produces, and decide how information is processed via the Analytical engine.

Q21. Mention the manner or roadmap that Microstrategy makes use of to question request and generate BI reports?

Ans: The manner or roadmap that Microstrategy used for producing BI reports

Step 1) Connect to Database

Step 2) Create Metadata

Step three) Create Databases ( in-memory ROLAP)

Step 4) Schedule ETL (Query Schedule)

Step 5) Create Reports and Dashboards

Q22. Mention different types of attributes in Microstrategy desktop?

Ans: Various varieties of attributes in Microstrategy computer encompass,

Implicit Attributes

Compound Key Attribute

Derived Attributes

Simple Attribute

Q23 Mention what's the difference among Custom organization and Consolidations?

Ans:

Custom group    Consolidations

A custom organization is a set of filters that can be positioned on a template. It is made from an ordered series of elements referred as custom group factors.

Consolidations are used to outline the information you want to view on your file. It allows you to organization characteristic factors in new methods with out altering the metadata and warehouse definitions.

Q24. Mention how are Intelligent Cubes distinct from normal cubes?

Ans: Intelligent Cubes are created robotically while a brand new document is administered towards the data warehouse.  Users don’t ought to determine the dice to which they want to attach. The logic to healthy consumer requests with the right Intelligent Cube is routinely dealt with within the Microstrategy platform.

Q25. Mention what are the business advantages of Microstrategy Narrowcast Server?

Ans: The enterprise advantages of Microstrategy Narrowcast Server is that it offers an inexpensive way to ship corporate data to untrained partners, personnel, and clients. Due to which choice makers have enough information to streamline a enterprise method in an effort to cut the running fees.

Q26. Is it viable that with Microstrategy Desktop you may be a part of statistics across heterogeneous information resources?

Ans: Yes. Microstrategy eight have extended the records modeling flexibility to consist of included perspectives of statistics across heterogeneous records shops. Data can come from anywhere- statistics warehouse, SAP BW, statistics marts, and any range of operational machine databases.  By mapping conforming dimensions from numerous or distinct resources, Microstrategy Desktop can join facts automatically from multiple in contrast to resources in the equal document record.

Q31. Mention whether a MicroStrategy is a MOLAP or ROLAP device?

Ans:

Relational on-line Analytical Processing or ROLAP gear do not utilize pre-calculated statistics cubes.

Multidimensional online Analytical Processing tools or MOLAP make use of a pre-calculated records units usually known as a records cube.

A MicroStrategy is a ROLAP tool.

Q32. Mention what's the difference among 2 tier,3 tier and four tier architecture in MicroStrategy?

Ans: The distinction is that,

2 Tier architecture: The MicroStrategy Desktop itself queries towards the Data warehouse and the Metadata without the intermediate tier of the Intelligence server.

Three Tier architecture: It incorporates an Intelligence server between MicroStrategy Desktop and the information Warehouse and the Metadata.

Four Tier architecture: It is same as 3 tier besides it has a further issue of MicroStrateyWeb.

Q33. Mention what's heterogeneous mapping?

Ans: Heterogeneous mapping enables the engine to carry out joins on in contrast to column names. If the consumer determines multiple expression for a given shape, the heterogeneous mapping will robotically take place whilst tables and column names require it.

Q34. Mention what's an Implicit characteristic?

Ans: An Implicit attribute has its personal expression.   It is a digital or constant characteristic that does not physically exist within the database due to the fact it's far created on the software degree.

Disallows

Extensions

Degradations

Q36. Mention what's truth degradation?

Ans: When the fact is at a higher level than the file display degree, then you may use truth degradation attribute to kingdom how the Engine degrades the facts to the lower degree. When you lower the level at which a reality have to be pronounced, you are using degradation.

Q37. Mention what is filtered set off?

Ans: You can restriction the wide variety of elements in a spark off using a filter.

Q38. Mention what is the difference among Report Limit and Report filter?

Ans:

Report Filter: It applies the “wherein” condition to the request despatched to the warehouse to fetch the outcomes.

Report Limit: It defines a fixed of standards used to limit the facts returned within the file records set after the report metrics are calculated.

Q39. Mention what's Prompt?

Ans: The spark off is not anything but an attribute via which you may adjust the contents of a file dynamically.

Q40. Mention distinct varieties of prompts?

Ans: Different styles of prompts are,

Level prompts: It allows you to decide the extent of aggregation calculation of a metrics

Object activates: It allows you to pick objects comprising a file at run-time

Value prompts: It permits users to kind a price.  It is used in conjunction with metrics or different activate for filters

Filter definition Prompt: This type of set off enable customers to determine how the document’s facts is filtered, primarily based on lists of attribute factors, attributes in a hierarchy or metrics.

Q41. Mention does it imply whilst you say in-reminiscence ROLAP?

Ans:

In memory ROLAP = ROLAP Architecture + Cube Architecture.

In-reminiscence ROLAP is an architectural extension of ROLAP wherein physical ROLAP cubes is living in-reminiscence in the Global Virtual Cube.
