Bitemporal Data Marts
Since more than 15 years I’m working with bitemporal data in Data Warehouse solutions. Meanwhile it is easy to design, build and populate tables for bitemporal data. But how to design and build bitemporal dimensional modeled Data Marts was new to me. Dirk Lerner does a very good job in explaining complex bitemporal stuff. His explanation helps you designing good SQL to populate bitemporal Star Schemas. Dirks presentation and explanation about bitemporal Data Marts is excellent!

Coaching Serie
/ SECRET SPICE - COACHING Serie
Coaching - Wie denn nun?
In loser Folge veröffentliche ich meine Gedanken und Erfahrungen rund um Datenmodellierung, temporale Daten oder viele andere Dinge aus der Welt des Coachings. Dazu gehören für mich Lösungsansätze unterschiedlichster Art, die manchmal generell, manchmal ausschließlich für eine bestimmte Situation geeignet sind.
Sehr oft wichtig und nicht zu vernachlässigen sind die fachlichen Anforderungen, die den Lösungsansätzen zugrunde liegen.
Wie die bereits veröffentlichte Serie zum PowerDesigner und die Serie zu temporalen Daten ist diese Serie für mich eine Art, kleine Schätze aus meiner Coaching-Welt, das ‘Secret Spice’, mit euch zu teilen.
In dieser Serie werdet ihr wahrscheinlich nicht so oft wie in den anderen Serien auf die Teammitglieder des Data Management Center of Excellence (DMCE) meines Lieblingskunden FastChangeCoTM treffen.

Coaching - How to do it?
In loose order I publish my thoughts and experiences around data modeling, temporal data or many other things from the world of coaching. For me, this includes approaches to solutions of the most varying kinds, which are sometimes suitable in general, sometimes exclusively for a specific situation.
Very often important and not to be disregarded are the business requirements on which the approaches to a solution are based.
Like the already published series on PowerDesigner and the series on temporal data, this series is a way for me to share with you little treasures from my coaching world, the 'Secret Spice'.
In this series, you probably won't run into the Data Management Center of Excellence (DMCE) team members from my favorite customer, FastChangeCoTM, as often as in the other series.

Qualität der Kundenbetreuung
Warum der Workshop mit TEDAMOH ein voller Erfolg war, hat aus unserer Sicht zwei Gründe. TEDAMOH schafft es komplexe Themen der Datenmodellierung anschaulich und klar darzustellen und damit alle TeilnehmerInnen mit unterschiedlichsten Hintergründen gleichermaßen abzuholen und mitzunehmen.

Quite ingenious
Dirk Lerner and his presentation on bitemporal modeling at first gave me a brain freeze. However, his explanation of using a Data Vault satellite to track changes over time and collapsing the changes into a dimension for analytics was not only a requirement for financial reporting in Germany but also quite ingenious.

Response quality to customers
From our point of view, there are two reasons why the workshop with TEDAMOH was a complete success. TEDAMOH manages to present complex topics of data modeling in a vivid and clear way and thus to pick up and carry along all participants with different backgrounds in equal measure.

Success with bitemporal knowledge
The first session at Data Modeling Zone Europe 2018 in Düsseldorf, was a session about bitemporal data by Dirk Lerner. The session was and is an extract from his current training Temporal Data in a Fast-Changing World, which is now available as open and private training.
At work I just started at a new customer and was part of the data warehouse team, who was assigned the task of building the Data Vault Data Warehouse. We were developing the Data Vault generator. At that point we used an end-date for the business time. I remember the complexity for updating the old records and the time for the server it costs to do this. Especially when you want to add rows in between. To load history, for example, from old sources.
The training is led by Dirk in an interactive way.
