Right now, we've got two to give you practice in drawing dataflow diagrams and one for data modelling. They're based on the Acme Fashion Supplies case study. The first two get you to work with dataflow decomposition and subsequent updates to the higher level dataflow diagrams. In the third, you create a partial Logical Data Model.

Each exercise has a link to its own answers page.

  • Process 1 Decomposition, Exercise 1: Acme Fashion dataflow decomposition

    Draw the decomposition of Process 1, Sell Product and Take Order, using the output from the interview with Bo Sibbutz, provided.

  • Top-level DFD Update, Exercise 2: Update the top level DFD with what was found in Exercise 1

    Take the answer to Exercise 1 and make any necessary changes to the top level dfd to reflect the new / changed dataflows and new / changed external entities involved.

    See how many points you score!

  • Logical Data Modelling, Exercise 3: Create a partial LDM from interview notes about the emailshots that Acme Fashion Supplies sends to its customers.

Exercise 1

It should take you three hours or so, maybe four or five. Make sure you give yourself enough quiet time to make a good start.

Come back to it later to maybe redraw it and to finish it off. Pencil and paper is best to rough it out. Get a good eraser - if you're anything like us, there's a lot of erasing and redrawing to be done as you get your head around things.

Everything you need is included on or linked to from the exercise page.

Exercise 2

This one should take no more than an hour or two. We've prepared a version of the top-level for for you to use in this this exercise. It has process 1 removed so there's room for you to put in your version. Links to it and the other material you'll need for the exercise is included on the exercise page

Remember, in Exercise 2 you're summarising, so two or more of the lower level diagram's dataflows may become just one in the top level. It's up to you to decide what you think should be included / left out, bearing in mind what's important to the business community.

Also remember, datastores that are private to a process (i.e. not used by any process that's outside the decomposition being drawn) should remain private to it.

Exercise 3

It should take you maybe two hours to draw the partial Logical Data Structure diagram, with another hour or two to list the attributes / data items of the new entities.
