Data Engineering¶
This covers the section all about data in the system: how it flows from and out of the system to the users, and how the data is stored. This dictates fundamentally how the system would work.
See diagram below for illustration.
Data Flow Diagram (DFD)¶
This illustrates the processes within the system and how data is converted from one form to another, as well as which data store a data will be located in..
Entity Relationship Diagram (ERD)¶
This illustrates how the data is structured with relation to one another.
