Like infrastructure architecture, data architecture is also an important activity which you should plan before starting the project, or make changes as needed during the course of the project. Data architecture involves planning the data fetching from source system, data manipulations and transformation as per the requirement and storing the output in Qlik Data format. This becomes an input for the Qlik Sense application.

Before actually starting to design the data architecture, you should know a couple of important file formats, like QVD (Qlik Sense application) and QVF (Qlik Data Files).
