“For traditional business applications, the schema is known in advance, so there is no need to use a graph database which has weaker enforcement of integrity. If instead, you’re dealing with at best a generic model to which it conforms, then a schema-oriented approach does not provide much. Instead a graph-oriented approach is more natural […]
“Many data warehouses contain sensitive data such as personal data. There are legal and ethical concerns with accessing such data. So the data must be secured and access controlled as well as logged for audits” — Michael Blaha. This is the third interview with our expert Dr. Michael Blaha on the topic Database Modeling. This […]
“ Use cases are rote work. The developer listens to business experts and slavishly write what they hear. There is little interpretation and no abstraction. There is little reconciliation of conflicting use cases. For a database project, the conceptual data model is a much more important software engineering contribution than use cases.“ — Dr. Michael […]

“Semantic technologies may be unfamiliar, but when you have used them for a while you will realise they are no harder than many other technologies…in fact I would argue they are easier.”– John Goodwin. On the topics of Semantic web technologies, ontology engineering, and linked data, I have interviewed John Goodwin. John is Principal Scientist […]
“The only obstacle to Semantic Web technologies in the enterprise lies in better articulation of the value proposition in a manner that reflects the concerns of enterprises. For instance, the non disruptive nature of Semantic Web technologies with regards to all enterprise data integration and virtualization initiatives has to be the focal point” –Kingsley Uyi […]

This is a follow up interview with Dr. Blaha on a related topic: Agile data modeling and databases. RVZ Q1. Many developers are familiar with the notion of agile programming. What is the main promise of agile programming? […]
I published another chapter of the new book on “Patterns of Data Modeling” of Dr. Michael Blaha. All together you can now download three chapters of the book: Tree Template, Models, and Universal Antipatterns. At the same time, I asked Dr. Blaha a few questions. At the end of the interview you`ll find some more […]
