Temporal data in a fast-changing world!

TED 01 Web

Over time, things change - things like customers, products, accounts, and so forth. But most of the data we keep about things describes what they are like currently, not what they used to be like. When things change, we update the data that describes them so that the description remains current. But all these things have a history, and many of them have a future as well, and often data about their past or about their future is also important. Tom Johnston

Nowadays, most data warehouses already store some kind of history of data. But what about events that took place at a different time than what the data warehouse represents to us? Or data that will be valid in the future? For example, future planned prices for products and goods or special prices for discount battles or sales promotions like the “Black Friday” in the United States.

What will I learn?

The Big Business Man smiled. "Time," he said, "is what keeps everything from happening at once. Ray Cummings, The Girl in the Golden Atom, novel (1922)

Dirk Lerner, the teacher of Temporal data in a fast-changing world! will focus in this class on methods and techniques for storing bitemporal data in a Data Warehouse and afterwards merging timelines of bitemporal data, e.g. Data Vault Satellites, to get data out of the Data Warehouse’s core layer. He will show bitemporal basics for a better understanding of loading data as well as the concepts to develop SQL queries to insert and update temporal data within a Data Warehouse. Finally, concepts to provide Star Schema Dimensions as non-, uni- or bitemporal objects will be demonstrated.

Day 1

On the first day of the Temporal data in a fast-changing world! training the attendees will understand the basic temporal concepts. They will practice how to model uni- and bitemporal database objects with Data Vault and how to load bitemporal data into a Data Warehouse.

Day 2

The second day of the Temporal data in a fast-changing world! training will focus on how to get data out of the Data Warehouse. How to merge timelines of Data Vault objects and provide temporal data within a Star Schema. The attendees will understand the concepts by doing a lot of practical exercises.

On both days real world examples will be shown and attendees will do several exercises and SQL-tutorials.

What is included?

Arrival, departure and overnight stay are not included in the training.

But,
the training includes a course material set, an eBook and SQL examples to download as well as drinks, lunch buffet and snacks in the breaks. Of course, there is also plenty of room for exercises, discussions and questions.

Every participant has the exclusive opportunity to join the Temporal Data Alumni and participate in the Temporal Data Alumni Meetups.

Please, note: You need to take your own laptop into the course!

Who is the class for?

As a Data Architect, Business Analyst, Data Modeler, Data Vault Expert, ETL developer, Data Warehouse Manager, BI Expert or BI Consultant you will get most out of this class.

If you are in doubt get in touch with us!

Where will the trainings take place?

Public training classes will take place in Frankfurt, Hamburg, Munich, Stuttgart, Cologne and Berlin. If another city is interesting for you, please get in touch with us.

In-house training classes can be offered on request.

Why are we doing this?

Thanks to everyone who took part in one of our presentations about temporal data, or has taken the time to reach out to us. Your positive feedback and success stories are what keep us striving to set up this training class and get even better!

Testimonials

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. Peter Avenant, Varigence - My thoughts on the Global Data Summit
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! There are not many sources to quote about this topic. Juan-José van der Linden, DataDenken
