2. ParallelPeriod

The ParallelPeriod work is part work, so it restores the current part, parent, predecessor, youngsters, and so on. It recovers a part dependent on the time measurement and a few conditions. 

3. Count and DistinctCount

The Count and DistinctCount are Numeric Functions. The check work figures the number of things present in a specific item like tuple, measurement, and so forth. The DistinctCount work accepts a Set_Expression as contention and returns a numerical worth which indicates the quantity of individual(distinct) things Present in that Set_Expression.

13. How to send SSRS Reports from SSIS?

Ans: SSIS can send SSRS report in various arrangements like Excel, PDF, and so on. This is accomplished by making a reported membership utilizing the Report director. In the reported membership, the organization of the SSRS report can be referenced alongside the email address of the beneficiary. sp_start_job is utilized to execute the reported membership.

14. Differentiate between a Matrix Report and a Tabular Report.

Ans: A Matrix is fundamentally the same as a table, however, it is designed to show information assembled by sections and columns, with total information at the convergences. A portion of the information you may hope to find straight can turn into a section header. This is like utilizing a rotate table in a spreadsheet.

The table and matrix data areas can show complex information connections by including settled tables, lattices, records, graphs, and checks. Tables and frameworks have an unthinkable design and their information originates from a solitary dataset, based on a solitary information source. The key contrast among tables and networks is that tables can incorporate just line gatherings, whereas frameworks have push gatherings and segment gatherings.

  • Microsoft SQL Server
  • Oracle
  • SAP BW
  • Hyperion Essbase
  • Microsoft SharePoint List
  • Teradata
  • OLE DB
  • ODBC
  • XML

19.Mention the tools used in MSBI

Ans: In MSBI, there are three essential tools they are:

  • SSIS – SQL Server Integration Services
  • SSRS – SQL Server Reporting Services
  • SSAS – SQL Server Analytical Services

SSIS – SQL Server Integration Services: it helps integrate the data arriving from various sources in the data warehouse. Saves the data using ETL (extract, transport, load) process at a centralised location. SSIS usually carries out bulk transactions. 

SSRS – SQL Server Reporting Services: the primary function is Making Reports. It produces reports in tabular, charts, and many other forms. SSRS is an efficient and platform-independent tool.

SSAS – SQL Server Analytical Services: it helps in analysing and sharing metadata, speed, security, multidimensional analysis, etc. it is similar to an SQL administration server. SSAS analyses data before updating it into the database. SSAS carries out analytical processing and data mining functions.

20. Explain control flow?

Ans: Control flow is a workflow of tasks to be executed in order. A Control Flow contains more than one task and containers executed during the package run. Control Flow can be created using the Control Flow tab in SSIS Designer, and SSIS provides three types of control flow elements.

Tasks -which provide functionalities

Containers - which provide structures in packages

Precedence Constraints - which connect containers, tasks within an ordered control flow, and executables.

Nesting of containers is supported in integration service architecture. Multiple levels of nested containers are included in the control flow. For example, a box contains a box inside, and that inside box also contains another box. And so on

21. How does a checkpoint work in a for loop?

Ans: Checkpoint stores the failed task in the package While performing multiple tasks in a package. If a task is failed in the checkpoint and we begin the package, then the checkpoint helps us to begin the failed task from the last point in the checkpoint file. When the task is succeeded, the checkpoint will automatically erase the task.

There are four types of checkpoints in the database they are :

  • Automatic
  • Indirect
  • Manual
  • Direct.

22. Differentiate views and Materialised Views?



  • A view is technically a virtual logical copy of the table created by query.
  • It does not store the resulting tuples of the query. It only stores the query expression
  • Storage cost is not associated with views.
  • SQL views have a standard architecture approach and design. A view has SQL standard definition.

Materialised view

  • Materialised views are the stored results of a view expressed in a database system.
  • The resulting tuples of the query and the query expression are stored in the database in the materialized view.
  • Storage cost is not associated with materialised views.
  • It does not have any SQL standard definition for a materialised view.

23. How can we do logging in to SSIS?

Ans: SQL Server Integration Services contains log providers to execute logging in tasks, packages, and containers. By logging, we can write custom messages, capture runtime information, troubleshoot packages, assist in auditing, etc. SSIS contains different log providers with which users have complete freedom to create specific log providers.

By the following steps, we can configure logging in to SSIS

  • For logging, we must enable the package and respective tasks.
  • Choose a suitable log provider and add a log to the package. Logs are created at the package level only.
  • Select the log schema information and events for every event you want to capture.

24.Define query parameters in SSRS?

Ans: When a parameter passes the SSRS RDL file through a query string, it is called a query parameter. We can pass multiple value parameters or a single value parameter.

25. Explain the Reporting Life Cycle in SSRS.

Ans:  In Reporting cycle consist of three stages they are:

  • Authoring
  • Managing
  • delivery

These three require some tools to work, and SSRS provides the required tools in reporting applications. Now let us know about the detailed stages involved. The given below is the representation of the stages.


In this stage, the report author defines the sources of data and report layout. You can design reports using a report builder 1.0 or report designer at this stage. You can also report by Report Builder 2.0 the latest version and use it depending on the SQL server you are working on.


In this stage, the author publishes the report to a centralised location where a report administrator scrutinises it for delivery and security purposes. SSRS database is the centralised location. When the report gets published, the administrator uses the report manager, custom-written scripts, share point, SQL, or third-party tools and manages published reports.


In this stage, the report is distributed to the intended users and is available in different output formats. With the SSRS retrieval mechanism, users can immediately update to the output format, and SSRS provides many delivery methods.

26. Define Report Model Project?

Ans:  A report model project is a template that contains data sources and data sets, and it is used in ad-hoc reporting. Ad-hoc reports are created with the help of a report builder, and they can be made using Report Server or BIDS.

27. What do you mean by Report Server Project?

Ans: It is a Business Intelligence Projects template installed by the visual studio, available in the New Project dialog box. RDL files are present and deployed on the report server for users to view the reported files.

28. What languages are used in SSAS?

Ans:  In SSAS, we use four languages they are:

  • Multidimensional Expressions (MDX)
  • Data Mining Extensions (DMX)
  • Structured Query Language (SQL)
  • Analysis Services Scripting Language (ASSL) 

29. How can you set up SSIS Packages on Production?

Ans: In SSIS, the project BUILD furnishes deployment manifest files. We must execute the manifest file and determine whether to deploy this onto SQL Server or the File System. We can alternatively import the package from SSMS from SQL Server or File System. SQL ServerDeployment is faster and more secure when compared to File System Deployment. 

30. Define OLAP

Ans: OLAP means Online Analytical Processing. OLAP is a technology that systematises a business's colossal database and organises complex analysis. With OLAP, users can easily extract data and query and analyse it from another standpoint. OLAP BI queries financial reporting, budgeting, sales forecasting, and other planning purposes and aid in trend analysis.

31. Explain a workflow in SSIS. What do you mean by a control flow and a data flow?


Workflow in SSIS: 

Workflow processes data in sequence order. Workflow is used in many businesses. A workflow is created if data is transferred between the system and the user. It is like a to-do list describing steps involved by visualizing complex procedures in a workflow.

Control flow :

Control flow is a workflow of tasks that are to be executed in order. A Control Flow contains more than one task and containers that are executed during the package run. Control flow is called the brain of SSIS. Control Flow can be created using the Control Flow tab in SSIS Designer.

Data flow: 

A data flow is a flow of data from a source to a destination. Unlike control flow, rules or loops are not present in the data flow. It gives inputs and outputs of anything in the system, also called DFD. data will flow between selected entities like sources, destinations, and transformations.

32. Mention the errors in SSIS and explain how error handling works?

Ans:  Errors occur in SSIS when a data flow component runs a transformation to column data and extracts data or loading data to destinations. With unexpected data values, errors occur.

Errors are categorised into three types they are:

  • Data conversion errors occur due to loss of significant or insignificant digits, truncation of strings, and unsupported conversions.
  • Expression evaluation errors: errors occur due to invalid operations or incorrect or missing values.
  • Lookup errors: errors occur when the lookup operation fails to identify a match in the lookup table

Error handling options are:

  • Fail Component: when an error occurs, then source, transformation, destination, etc. will fail.
  • Ignore failure: row failures are ignored.
  • Redirect Rows: in this, the task will not fail but failed rows are sent to failed output and successful rows to required destinations. 

33. Explain the concept of variables and also shed light on what variable scope is?

Ans:  A Variable is a named object which is used in the SSIS package. It stores values and 

Various SSIS components refer to those in the package execution. Users can configure a variable and can assign a value and update in the run time. The SSIS package has two types of variables: user-defined and system-defined.

The scope is the availability of a constant, procedure, or variable used by another procedure. The scope of a variable is determined when we declare it. There are three types of scope levels. 

  • Procedure level
  • Public module level
  • Private module level

34. Explain the Ragged Hierarchy?

Ans: It is a user-defined hierarchy and consists of many levels. Here Hierarchy means an arrangement of items. In SSAS, it is a multidimensional database. Hierarchies analyse factual data logically. Each Hierarchy consists of one or more than one levels. At the end of the Hierarchy, we find leaf members. Types of Hierarchies are:

 Balanced Hierarchies, Unbalanced Hierarchies, and Ragged Hierarchies

35. What Are Aggregations in SSAS?

Ans: Precalculated summaries of data from cells are called Aggregations. They enhance query response time by preparing answers before questions are asked. They are stored in a multidimensional structure of cells, depending on the percentage of calculations and storage modes like ROLAP, MOLAP, and HOLAP.

36. What are PerformancePoint services in MSBI?

Ans: Performance point service or PPS is a BI tool used to display information dashboards by using the SharePoint Platform. It was added as a service within the enterprise version of SharePoint 2010. It is a service application that analyses and monitors business data and builds dashboards, Key Performance Indicators (KPIs), and scorecards.

37.What is OLAP? How is it different from OLTP?

Ans: OLAP means Online Analytical Processing. OLAP is a technology that systematises a business's colossal database and organises complex analysis. It provides data analysis for businesses to make better decisions. The main objective is data analysis but not data processing.

OLTP means Online Transaction Processing System, an online database modifying system and database query answering system. Both OLAP and OLTP are online systems.
