Join us as we get together for an Arthouse Movie Friday event to see the A24 dark comedy /romance / psychological-thriller, THE DRAMA! The film stars Zendaya and Robert Pattinson as a happily engaged couple whose relationship is challenged when one discovers unsettling truths about the other. Here are details, a trailer and our plan for this event: DESCRIPTION: The film follows a happily engaged couple whose relationship is put to the test when an unexpected turn sends their wedding week off the rails. The film comes from A24, is written/directed by Kristoffer Borgli stars Zendaya, Robert Pattinson, Mamoudou Athie, Alana Haim, Hailey Gates and Zoë Winters. QUICK WORD OF WARNING: The film hasn’t screened for critics yet and most of the details are being kept tightly under wraps. But, early buzz (possibly promotional) says the film is a brilliant psychological thriller/romance but also provocative, twisty and some contains occasional uncomfortable viewing! I love the cast and trailer, so look forward to seeing for ourselves!

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
