It's more than just input and query, sometimes it's also about a concept
Databases reveal their full potential if certain aspects are considered, I call this aspects concepts. Some concepts are more general meaning the implementation of these concepts will have an
impact on the overall architecture of the analytical pipeline like the immutability of data sets (requested by the lambda data architecture) or CQRS, and some concepts are more specific to a
specific kind of question, like star schema and slowly changing dimension. These concepts determine what data management systems are used and how the data has to be modeled / organized to adhere
to the broader and also the narrower concepts,
For this reason there will not be a single site for data modeling, but data modeling will be spread across the topics store and process.
