Thanks for reading my article.To answer your first question – actually I found only one official presentation about best practice for Data Modeling: Moreover XSA which is the new environment for SAP HANA does not support SQL scripted views, so before you migrate from XSC to XSA you will need to migrate all obsolete objects (SQL scripted views, Analytic/Attribute views etc) into the new objects (the sooner the better). There is a workaround for that limitation, which can help to fulfill requirement of passing multiple values directly to the query. Table functions are functions that produce a collection of rows (either a nested table or a array) that can be queried like a physical database table.
