Which technique would the business analyst (BA) consider to show the transformation of data?
A . Sequence diagram
B . Data flow diagram
C . Data modelling
D . Flowchart

Answer: B

Explanation:

A data flow diagram illustrates the movement and transformation of data between externals (entities) and processes. The output from one external or process is the input to another. The data flow diagram also illustrates the temporary or permanent repositories (referred to as data stores or terminators) where data is stored within a system or an organization. The data defined should be described in a data dictionary.
