Data analysis and reporting have traditionally operated using tailor-made data models after the operational data has been extracted and transformed. Behind it we find that the application development uses a data model which is much less suited for data analysis and reporting. One of the main reasons for this mismatch is the approach denoted as functional decomposition, where the system is designed based on functions as described in requirements, use-cases, product backlogs etc. Moreover, this approach is the one that most application developers take as a default choice.

What if there is another way to do the application design that explicitly allows the data to play a much more prominent role in system decomposition? What if this alternative approach can bridge the gap between application development and data analysis and reporting?

Join and explore an alternative to complex system design that emphasizes data ownership with foundation in business capabilities, which presents a very different opportunity for rich data analysis and reporting. The talk is based on real-world cases from the domains for healthcare and insurance.
