Topic #: 4
You are the business analyst for your organization and you're creating a data flow diagram to show how information is input, processed, stored, and output from a system. Which element of a data flow diagram represents a process that transforms data by combining it with other data?
The data process describes the transformation of data in some way, either combining the data, reordering the data, converting the data, filtering the data, or other such activities.
Answer, B is incorrect. An external entity is a source or destination of data. It is represented as a labeled rectangle.
Answer, A is incorrect. Data flow identifies where data is being moved between a data process and an external entity, a data store or another data process.
Answer, D is incorrect. Concatenation isn't a valid component of a data flow diagram so this choice is not valid.
