3.Give the structure of an application in Qlik Sense?

The structure of an application in Qlik Sense is similar to that of a Microsoft Excel file. Data is pulled from a source, which is a dot-connect base tool.

The main components of an application include a script that loads data from different sources, forming a data model using Starscream, Starscream, or Snowflake schema. The U-Appotion, which sits on top of this data model, represents the data model and creates a user interface.

The performance of the UI and logic at the UI level are based on the data model design.

4.List out the different architectures used to create applications in Qlik Sense?

There are three different architectures used to create applications in Qlik Sense: source layer, tier two, and presentation layers.

The source layer involves a source layer where data is reset, a dot QV at file for the clicks and application, and a script that loads data from the source system.

The final application, which the end user will view, is developed using this architecture.

Tier two involves creating a dot QVF file and another clicks and application, which publishes the application to the end user.

The script, which is the ETL logic created, is then used to create transformations and create the UI part. This approach divides the task of one QVF file into multiple QVF files for parallel processing and reduces the load on one QVF file.

The third layer is presentation layers, which create a local version of the data in the source system.

The first application creates QVF files without any changes to the data, creating a local version of the data in the form of QVD files.

The second layer has a script with ETL logic of the data model, pulling data from the QVD files with the desired ETL logic.
