This episode closes out the mini series about data, and this time we talk about data modeling. Data models are some of the things that I have seen the least often in projects over the last two decades. Why is that? Is it because it is too geeky, or not interesting enough compared to, say, a process model in BPMN?

But being clear about data is important when it comes to designing solution architectures (and in other use cases, such as regulatory compliance), and the three questions that you have to answer are:

• What is the data that we are talking about?
• Where do I store data and how is it transformed? 
• Where do I ask for the data?

In this episode of the What's Your Baseline Podcast we talk about:

• Conceptual / logical data modeling
• Canonical data models versus information asset views
• Application and data (from a logical perspective) - interface designs
• Data used in the context of processes
• Application diagrams and physical data models
• Data mapping in screen diagrams (wireframes)
• Screen navigation models for context
