    How we, TEDAMOH, define Seminar, Training and Workshop

    Training, seminar and workshop - these terms are often used synonymously. They all refer to further education and training events, but the objectives differ. Roughly speaking, seminars convey theoretical knowledge, trainings are practically oriented and workshops provide a framework in which the participants can acquire knowledge themselves.

    If you would like to be trained in the usage of a new software or method, such as dealing with temporal data, training is a suitable option. Because you can learn and practice how the program or method works by yourself.

    There is a new process for reporting company figures in your company that affects the presentation of your data in your data warehouse? Then it's time for a seminar that will give you the necessary know-how about the process.

    You want to create a new application for the customers of your data warehouse and don't know how the dashboard should be designed? Then a creative workshop, e.g. with design thinkers to help the BI team, is exactly the right thing. Completely new ideas and solutions can be developed detached from everyday business.

  • Bitemporal Affront

    Or the battle announcement of the incoming interface

    The BI Center of Competence (CoC) has decided to use bitemporal data storage when setting up a new data warehouse for one of the business units of the fictitious company FastChageCo™.

    BI CoC is well advanced in the bitemporal implementation of Data Vault database objects as well as loading patterns. The already connected systems via formally defined incoming interfaces have worked without problems so far.

  • Bitemporal Data

    If everything would happen at the same time, there would be no need to store historic data. We, the consumers of data, would know each and everything at the same instant. Beside all the other philosophical impacts, if time wouldn’t exists, is data still necessary?

    (Un)fortunately time exists and data architects, data modelers and developers have to deal with it in the world of information technology.

    In this category about temporal data I will collect all my blogposts about this fancy topic.

  • 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!

  • Data Modeling Zone EU/US 19 #DMZone

    OK, for those of you who just want to grab a promotion code... I'll make it short 😂:

    TEDAMOH

    As a speaker at both conferences I give you 15% on the DMZ EU and 20% on the DMZ US. You can register here.

    For those of you who are also interested in what I'm going to talk about, a few more informations:

  • Die Bedeutung von bitemporalen Daten

    Ich war sehr zufrieden mit Dirk Lerner's "Temporal Data in a Fast-Changing World" Training.

    Die Schulung beantwortete alle meine Fragen zur Bitemporalität, die in anderen Data Vault-Schulungen nicht so deutlich angesprochen wurden.

  • Enterprise Data & BI & Analytics 19 #EDBIA

    I am pleased to say that I will be participating at this year’s Enterprise Data & Business Intelligence and Analytics Conference Europe 18-22 November 2019, London. I will be speaking on the subject ‘From Conceptual to Physical Data Vault Data Model’ and (for sure) on my hobby horse subject temporal data: ‘Send Bi-Temporal Data from Ground to Vault to the Stars’. See my abstracts for the sessions below.

  • Methodik zur Lösung bitemporaler Aufgaben

    Dirk hat eine sehr gut strukturiertes Training über temporale Daten durchgeführt.

    Sie hat mir sehr geholfen, mein Wissen über dieses anspruchsvolle Thema zu erweitern.

  • Methodology to handle bitemporal challenges

    Dirk set up a very well structured training on temporal data.

    It helped me a lot to develop my knowledge on this challenging topic. 

  • 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 [Link].

    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.

  • TEDAMOH @ #TDWI - Let’s talk

    We, Stephan and myself, are looking forward to welcome you at the TDWI Conference at the MOC Munich from June 24th - 26th, 2019! Meet us at our booth, discuss bitemporal topics, data vault or data modeling at all with us and attend one of Dirk Lerner's lectures:

    • Model-driven decision making [Link], together with André Dörr and Mathias Brink
    • FBI at Bosch - a real journey through the depth of "data water" [Link], together with Marc Wiesner, Director Finance BI Competence Center, Robert Bosch GmbH
    • Temporal

    • Temporal data modeling - an expert knowledge

      With this training, Dirk and team manage to convey expert knowledge in a fantastic learning atmosphere through their friendly and professional manner.

      My experience of the TEDAMOH training "Temporal Data Modeling" summarized in a video.

    • Temporale Datenmodellierung - ein Spezialistenwissen

      Dirk und Team schaffen es mit diesem Training, ein Spezialistenwissen, durch ihre sympathische und professionelle Art in einer tollen Lern-Atmosphäre zu transportieren.

      Meine Erfahrungen über das TEDAMOH Training „Temporale Datenmodellierung“ im Video festgehalten.

    • The depth of bitemporal data

      I was very satisfied with Dirk Lerner's "Temporal Data in a Fast-Changing World" training.

      The training answered all my question about bi-temporality, not addressed in other Data Vault trainings with such clarity.
