2. What chart types do we use in QlikView Admin?

In QlikView Admin, we generally use bar charts, line charts, combo charts, scatter charts, grid charts, etc.

3. Explain Set Analysis in QlikView.

Mostly used in aggregated functions like sum (year), avg, max, min, etc., set analysis is used to define a set (or a group) of data values.

4. Define Trellis chart.

In the trellis chart, we can create an array of charts based on the first dimension. It is basically a grid of small charts or a repetition of charts. Bitmap charts can also be made up of the trellis display.

5. Explain Mini chart. What do you mean by sub-reports and how can you create them?

In QlikView, with the help of a mini chart, we can set the type of modes, instead of values, in the table mode. We can also set colors for the chart.

6. What is a Pivot table?

A pivot table is better at the time of grouping. We can also show a pivot table like a cross table, which is a beneficial feature. However, there is a disadvantage with pivot tables, i.e., if we have to sort a pivot table, then we have to sort it first according to the first dimension, then to the next.

7. Which graph can you use for 2 years' difference sales?

A bar graph can be used for this purpose.

8. What is a Straight table?

A straight table is much better at the time of sorting when compared to the pivot table as we can sort the former according to any column as per our choice. However, it is not good for the grouping purpose.

9. How many dimensions can you use in a Bar chart?

In a bar chart, we can use only two dimensions.

10. Which QlikView object has only expression and no dimension?

Gauge chart and list box have only expression and no dimension.

11. How can you use Macros in your application?

We can use macros for various purposes, such as reloading the application and creating an object.

12. What do you understand by layers in QlikView?

Layers are basically set on sheet object properties in the layout tab, where there are options such as Bottom, Top, and Normal, respective to the numbers −1, 0, and 1.

13. What are Dimensions?

Dimensions allow data examination from various perspectives.

14. Explain Normalized data.

  • Normalized data: By saying normalized data, we mean the well-structured form of data, which doesn’t have any repetition or redundancy. It is a kind of relational data mainly used in OLTP-like stuff.
  • Denormalized data: Along with normalized data, we have denormalized data as well. It is a whole bunch of data without any relationship among themselves, with the possibility of redundancy. It’s mainly used in OLAP-like stuff.

15. What is Star Schema?

Star schema is the simplest form of a dimensional model, in which data is pre-arranged into facts and dimensions.

16. What is Snowflake Schema?

A snowflake schema is a different form of the star schema. A snowflake schema is used to improve the presentation of particular queries.

17. Explain IntervalMatch.

IntervalMatch prefixes with the load statement that is used for connecting different numeric values to one or more numeric intervals.

18. Explain the IntervalMatch() function.

The IntervalMatch() function is used to generate data buckets of different sizes.

21. What are the new features in QV 11?

Container object, granular chart dimension control, actions like clear filed, metadata, etc. are some of the new features in QV 11.

22. Explain Join and its types.

Join is used to convert the given data, and whenever we use joins for converting data it is known as data merging.
It has many types:
a. Left join
b. Right join
c. Inner join, etc.

23. What is Left Join?

Left join specifies that the join between two tables should be left join; it uses before the word ‘join’. The resulting table only contains the combination among two tables with the full dataset from the first table. When we have more than one common field between two or more tables, then we have synthetic keys.

24. Define Right Join.

Right join specifies that the join between the two tables should be right join; it uses before the word ‘join’. The resulting table only contains the combination among two tables with the full dataset from the second table.

25. Explain Inner Join.

Inner join specifies that the join between the two tables should be inner join. The resulting table should contain the full dataset from both tables.

26. What are Modifiers?

Modifiers deal with the Fields name.

  • Bookmark01: Represents the Bookmark name

28. Explain the 3-tier architecture of QlikView Application.

  • Tier I: Raw data is loaded, and QVD is created
  • Tier II: QVD is converted in business login and the requirement of business and data model is created.
  • Tier III: Reading all QVD from Tier II, a single QVW is made.

29. How does QlikView store data internally?

QlikView stores data in QVD as QVD has data compression capability. QlikView has better performance than other BI tools because of its memory analytics approach.

30. Explain the restrictions of Binary Load for a QlikView Developer.

Binary Load can be used only for one application, i.e., we can only read data from one QVW application. Moreover, set scripts is also a restriction.

31. For a QlikView Administrator, differentiate between Subset Ratio and Information Density.

  • Subset Ratio: It is used for easily spotting problems in the key field association. It is only relevant for key fields as they are present in multiple tables and do not share the same value.
  • Information Density: It is the field that contains the percentage of rows with non-null values.

32. What is the use of Optimized Load?

Optimized load is much faster and preferable especially for large sets of data. It is possible if no transformation is made at the time of load and no filtering is done.

33. Differentiate between Keep and Join.

Keep and Join do the same functions, but keep creates two tables whereas join merges two tables to create one table. Keep is used before the load or select statement.

34. Define Synthetic Key.

A synthetic key is the key used when two or more tables consist of more than one common column among them.

35. What is Incremental Load in QlikView Architect?

Incremental load is nothing but loading new or changed records from the database. With the help of QVD files, we can use incremental load.

  • Set: It assigns a variable to a value without assessing the expression.
  • Let: It assigns a variable to a value after assessing the expression.

37. Define QlikView Resident Load.

Resident load is a part of loading data in the QlikView application. It is used for loading the data in tables, which is already loaded in the Qlikview application.

38. How can you optimize a QV Application?

A QV application can be optimized by creating QVDs for data. When the complete QVW application is changed into a QVD, then this QVD will be stored in the RAM.

39. What is Mapping Load?

Mapping load is used to create the mapping table that can be used for replacing field values and field names.

40. Define Apply Map.

Apply map is used to add fields to tables with the help of other tables. It can be used as a join.

  • QlikView Server is a program that is installed on a computer with various CALS allowing users to access the QV files on the server.
  • QlikView Publisher is a program that has centralized control on our QV files and manages how and when they are loaded and distributed.

48. What do you understand by the Snapshot View of a table?

By this option, we can see a number of tables and related associations.

49. How can you bring data into QV?

We can use ODBC, OLEDB, or SAP connectors as a kind of data connection.

50. How can you handle Early Arriving Facts?

We can load data from ODBC, OLEDB, or SAP connectors with the help of the select statement, and we can load files like Excel, Word, etc. by using the table syntax.

51. What type of data do we use generally?

We use flat files, Excel files, QVDs, etc. as data.

52. Elucidate QlikView.

QlikView is the Business Intelligence tool used by the University of St Andrews. With QlikView, data from different university systems are combined and presented in a single dashboard in an easy and understandable way.

QlikView dashboards at the University of St Andrews are built on the following principles:

  • Dashboards must be effective to use.
  • Dashboards must support users in carrying out their tasks.
  • Dashboards must provide the right kind of functionality.

58. What are the key differences between QlikView and any other standard statistical software packages (SAS, SPSS, etc.)?

The key difference is in terms of the database used. While SAS is useful in the case of metadata and SPSS is good for analysis; QlikView offers quite a simple visualization that matches MS Excel filtering.

When comparing QlikView with the other two, it is the most user-friendly and the fastest in terms of generating diverse dashboards/templates.

In terms of calculations, advanced statistics options are limited in QlikView.
For market research and analysis, SPSS has direct facility algorithms.

59. What are QlikView Annotations?

With the new annotations collaboration object, QlikView users can engage in threaded discussions with the QlikView content. A user can create notes associated with any QlikView object. Other users can then add their own commentary to create a threaded discussion.

Users can capture snapshots of their selections and include them in the discussion so that others can get back to the same place in the analysis when reviewing notes and comments. Also, QlikView captures the state of the object (current selections), as well as knows who has made each note and comment and when and how a decision was made.
