Y12 Notes on describing organisations by DFDs and ERDs

Systems life cycle / Data Flow Diagrams / DFD Tasks

Entity Relationship Diagrams / Data Dictionaries

Introduction
 

These help sheets are adapted from a previous Databases unit.

The emphasis for the new course is on handling data, not on full-blown database development and systems analysis. However, since you are so good at databases, I consider that a little more depth of understanding will be good for you all…

Enjoy!
