Full Scale Data Architects at DMZ 2017

As already mentioned in my previous blogpost I will give a talk at the first day of the Data Modeling Zone 2017 about temporal data in the data warehouse.

Another interesting talk will take place on the third day of the DMZ 2017: Martijn Evers will give a full day session about Full Scale Data Architects.

Ahead of this session there will be a Kickoff Event sponsored by I-Refact, data42morrow and TEDAMOH: At 6 pm on Tuesday, 24. October, after the second day of the Data Modeling Zone 2017, all interested people can meet up and join the launch of the German chapter of Full Scale Data Architects.

Data Modeling Zone 17

After all, I am very happy to be a speaker at this year's Data Modeling Zone in Düsseldorf. Again, like at the Global Data Summit, I'm talking about one of my favorite topics: Temporal data in the data warehouse, especially in connection with data vault and dimensional modeling.

Fact-Oriented Modeling (FOM) - Family, History and Differences

Months ago I talked to Stephan Volkmann, the student I mentor, about possibilities to write a seminar paper. One suggestion was to write about Information Modeling, namely FCO-IM, ORM2 and NIAM, siblings of the Fact-Orietented Modeling (FOM) family. In my opinion, FOM is the most powerful technique for building conceptual information models, as I wrote in a previous blogpost.

Global Data Summit

I am very pleased to be speaking at the Global Data Summit in Golden, Colorodo this year. I am talking about one of my favorite topics: Temporal data in the data warehouse, especially in connection with data vault and dimensional modeling. The title is:

Bitemporal modeling for the Agile Data Warehouse

The talk is a 5x5 presentation, that is 5 slides in 5 minutes. Afterwards, the participants have the opportunity to discuss the topic intensively with me in a 90-minute whiteboard session.

FastChangeCo - A Fictitious Company

The company FastChangeCo is a fictitious company I developed in 2015 to illustrate problems, challenges and opportunities our customer had in their projects. I used FastChangeCo successfully during my talks, workshops, trainings, coaching and projects.

FastChangeCo is a company founded in the early 20th century. Today, we would say it was a Start Up. The founder, Mr. Fast, had great ideas for building assembly lines which came up in the early 20th century used by Ford and others. During the following decades his company grew to become a big player in the nineties of the last century.
Nowadays, FastChangeCo has thousands of employees and thousands of products in different industries and billions of revenue.

  • FOM

    Fact-Oriented Modeling (FOM) stands for a family of fact-oriented conceptual modeling methods. FOM facilitates easier communication about the conceptual model between the modeler and the domain expert by verbalization of concrete examples in the language of the domain expert, a design process as a guide for creating the model and the focus on elementary facts. The most popular methods in this family are Cognition Enhanced Natural Language Information Analysis Method (CogNIAM), Second Generation Object Role Modeling (ORM 2) and Fully Communication Oriented Information Modeling (FCO-IM).

  • 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.
