Ans: QlikView is one of the top business intelligence tools which provide end-to-end platform services. The main operations included are data integration, user-driven business intelligence, and data analysis. The QlikView business tool helps users to convert the raw data into a useful one. This tool sometimes acts as a “Human brain” and mainly works on the business association. This software tool was found in 1993 in Lund, Sweden, and is now based in King of Prussia, Pennsylvania, United States.
Ans: The following are the unique features of QlikView;
· QlikView helps in data association which is maintained automatically.
· The structure, data, and calculations of the QlikView report are held in RAM.
· Data is compressed to 10% of the original size.
· can perform visualization using colors.
Ans: User can create the QVD file using the following syntax;
Ans: The following are important charts that can be used in QlikView Admin;
· Line charts
· Bar charts
· Combo charts
· Grid charts
· Scatter charts.
Ans: The incremental load is nothing but loading of new or changed records from the multiple data sources into the QlikView software tool.
Ans: A dashboard is a type of QlikView document which shows many data matrices together and values can be stored in the sheet objects. These stored objects can change dynamically upon the selection of certain values in the datasheet objects.
Ans: The master calendar in QlikView is required to know when we want to create additional data values which are not already existed in the original data source. These data objects’ later can be analyzed with the help of a master calendar.
Ans: A pivot table can be defined as a table pf summary that allows the user to extract important information from a large data set.
Ans: Layers in QlikView are set on datasheet object properties in the dashboard layout tab. Where you can view them like an option like a top, bottom, and normal, a respective number ranging from 0, 1, and -1.
Ans: Join in QlikView gives the resulting record data which are accessed from one or more tables. These tables contain column which is concatenated only when we append the rows from one table to another.
The types of join are;
1. Left join
2. Right join
3. Inner join
4. Outer join
Ans: The following are the important advantages and disadvantages;
· Data sharing is possible
· Data interpretation and analysis
· Self-service control tool
· Low maintenance cost
· High data security
· Direct and indirect data search is possible
· Cheaply available software tool
· Sometimes there will be a chance of getting inefficient real-time data analysis
· Less RAM storage limit.
Ans: The below are the few purpose and uses of the QVD file;
· Helps to increase the load speed
· Incremental load is also possible
· Ease to maintain the file
· Data consolidation is also possible
· Separation of roles
· Decreases the data load on servers.
Ans: QlikView server helps to host the documents, user details, and objects whereas the QlikView publisher is a component of the QVS data file, which is responsible for performing data reduction, distribution, accessing, and managing the data contents.

Skew () is a type of statistical aggregate function that measures the symmetry in a distribution curve.
Ans: The two types of match () function in QlikView are Match () and WildMatch ().
Ans: A multi-box is a type of compressed table that shows the multiple table data fields.
A list box is also a type of compressed table that shows all the data values of any single table fields which stores in the form of lists.
