QUESTIONS ON CERTIFICATION

WE ALREADY HAVE THE BOOK (Building a Scalable Data Warehouse with Data Vault 2.0) WHAT CAN WE LEARN FROM THE CLASS?

  • The class includes a certification set by the inventor Dan Linstedt.
  • The class covers topics not found in the book, for example, hybrid Big Data architectures, best practices for Hadoop, cloud-based business intelligence solutions, real-time ingestion, and analysis of data, managed self-service BI, advanced modeling constructs, some conceptual theories and models.
  • The class encourages unique discussions between the attendees and the trainer.
  • In addition, the class includes a certification to the “Certified Data Vault 2.0 Practitioner” which is more and more requested in the industry.

When we proposed the book to Dan Linstedt, we had a unique approach: get as much into the book as possible to increase the understanding of the Data Vault concepts in the industry. However, the number of pages between both covers has been limited by the publisher. Therefore, some concepts are missing in the book:

  • Best practices for integrating Hadoop and other Big Data architectures.
  • Hybrid Big Data architectures.
  • Cloud-based business intelligence.
  • Real-time ingestion and analysis of data.
  • Managed Self-Service BI.
  • Advanced modeling constructs.
  • Additional conceptual theories and models.

The class encourages unique discussions on these topics (and the ones found in the book) between the attendees and the trainer. Our goal is to make the class a unique experience for you in this regard.

I'M ALREADY DATA VAULT 1.0 CERTIFIED. WHAT IS THE VALUE OF DATA VAULT 2.0?

Data Vault 1.0 is focused on the Data Vault model. In that sense, Data Vault 2.0 represents an upgrade that covers the following pillars:

  • The extensible data model where new data sources are easy to add.
  • The agile methodology is based on Scrum and the disciplined agile methodology and uses the data model for a rapid build-out of the data warehouse.
  • The reference architecture supports not only structured data sources but also semi-structured and unstructured data sources such as Hadoop and real-time systems.
  • The standardized loading patterns are optimized for loading performance and support generable ETL patterns to load massive amounts of data in a short time.

In addition, the following concepts are supported by Data Vault 2.0:

  • Best practices for integrating Hadoop and other Big Data architectures
  • Hybrid Big Data architectures.
  • Cloud-based business intelligence.
  • Real-time ingestion and analysis of data.
  • Managed Self-Service BI.

This is all about Big Data and organizational support for data warehousing.

I'M ALREADY USING DATA VAULT IN MY PROJECTS EVERY DAY. WHY SHOULD I GO FOR TRAINING?

The markets are on Data Vault 1.0 and prospects don’t understand the differences between Data Vault 1.0 and 2.0. Training also provides you the opportunity to learn the underlying concepts of what you use every day and get some new and fresh ideas for your projects.

WHAT IS THE VALUE OF CERTIFICATION?

  • Certification is a qualification that helps to get into Data Vault projects.
  • Some clients already require that consultants are certified in Data Vault 2.0.
  • Certification shows proof that students have understood the fundamentals of Data Vault 2.0.
  • Certification increases the hourly rate of consultants.

WHAT IS THE CERTIFICATION PROCESS?

This class can be completed with an online certification test. The certification is a multiple choice test with 100 questions in 120 minutes. 80% of the points required to pass. 20% of the students typically fail. The certification test can be taken online after the event. The first attempt should take place soon after the course, we recommend the following weekend. We recommend to do the retake 3 months after the course.
The certification is granted and organized by Dan Linstedt. Dan is also asking for feedback from the attendees. After successful completion of the test, the student is granted the title “Certified Data Vault 2.0 Practitioner”. The student’s name will be published on datavaultcertification.com.

IS CERTIFICATION INCLUDED IN THE TRAINING?

Yes. Students receive a certificate of participation from Olschimke Beratungsgesellschaft mbH and can take private certification for the Certified Data Vault 2.0 Practitioner (CDVP2) by Dan Linstedt. If you don’t want to get certified, you can remove this option during registration for the training. By doing so, the training becomes a little cheaper.

IS THE CERTIFICATION TAKEN DURING THE TRAINING?

No. This is not possible anymore.

IS IT POSSIBLE TO HAVE A FREE RE-TAKE ON THE CERTIFICATION?

Yes. One free retake (online) is possible.

ARE THREE DAYS OF TRAINING REQUIRED TO ATTEND THE CERTIFICATION TEST?

Yes. It is not possible to receive a certification without attending on a Data Vault 2.0 Boot Camp.

HOW HIGH ARE THE COSTS FOR AN IN-HOUSE TRAINING?

In-house Boot Camps have the same price as public ones.

ARE THREE DAYS OF TRAINING REQUIRED TO ATTEND THE CERTIFICATION TEST?

Yes. It is not possible to receive a certification without attending on a Data Vault 2.0 Boot Camp.

CAN I HAVE A FAIR CHANCE TO PASS THE EXAM WITHOUT ATTENDING THE COURSE BUT STUDYING THE BOOK?

It is not possible to take the certification without attending the course.

IS IT POSSIBLE TO ADD CERTIFICATION AFTER THE TRAINING WAS RECEIVED?

Yes. It is possible for 750 €. However, the certification cannot be added during the Boot Camp training It is not possible to take the certification without training. The training is mandatory.

IS THERE A ``CERTIFIED DATA VAULT 2.0 MASTER`` CERTIFICATION?

No. We currently do not offer such certification to the public.

WHERE IS THE DIFFERENCE BETWEEN CDVM AND CDVP2™?

CDVDM = Certified Data Vault Data Modeler

It covers the basics of Data Vault Modeling, and certifies the individual to be focused on the Data Modeling components alone. It covers Hubs, Links, and Satellites. The exercises provided are for Data Modeling components only.

CDVP2 = Certified Data Vault 2.0 Practitioner

It covers Architecture, Methodology, Implementation, and Data Vault Modeling. This course certifies individuals with project management to the implementer to data modelers and QA. We discuss language, common terminology, implementation standards, and best practices. We cover business data vaults, NoSQL platforms, Disciplined Agile Delivery, teaming, and data integration specifics. This class is the only one available by the creator and founder of the Data Vault itself. It has been upgraded to take advantage of Big Data solutions. We also cover MPP, data distribution, big data problems, data science and semi-structured information delivery. Included in this class are the standards, naming conventions and best practices for data movement and query logic – which you will not find anywhere else.

The practitioners come out of this course with a complete well-rounded knowledge of how and why to build enterprise global systems that meet the demands of today’s business intelligence programs.

QUESTION ON BOOKING THE CLASS

IS IT POSSIBLE TO ADD CERTIFICATION AFTER THE TRAINING WAS RECEIVED?

Yes. It is possible for 750 €. However, the certification cannot be added during the Boot Camp training It is not possible to take the certification without training. The training is mandatory.

DOES IT MAKE SENSE TO ATTEND THE MODELING CLASS?

This depends on the already existing knowledge on Data Vault. If working in a Data Vault project took place and knowledge about the advantages of non-historized links for the provision of facts exists (just one topic from the modeling class), the modeling class is not necessary.

During the Data Vault 2.0 Boot Camp we talk about modeling, but not as detailed as in the modeling class.

QUESTIONS ON CLASS STRUCTURE

IS IT POSSIBLE TO CUSTOMIZE AN INHOUSE TRAINING TO OUR NEEDS?

Yes. We can always provide a customized inhouse training with content tailored to the needs of the client. Agenda and topics can be chosen from Data Vault 2.0 Boot Camp with Private Certification, Basic Data Vault 2.0 Modelling, and other topics available by Dan Linstedt.

IS THERE A MINIMUM OF PERSONS NEEDED TO RECEIVE AN INHOUSE TRAINING??

Yes. We offer inhouse trainings only to groups of 8 attendees or more.

IS IT POSSIBLE TO COMPRESS THE BOOT CAMP TO LESS DAYS WHEN PROVIDED INHOUSE

Yes. It is possible to provide the Data Vault 2.0 Boot Camp with Private Certification in 2 extra-long days instead of 3 normal days. Every day would start at 08:30 in the morning and go until 08:30 in the night. However, this setting is thought for students.

IN WHICH LANGUAGE WILL THE TRAINING BE DELIVERED

Typically in English, but in Germany, Swiss or Austria, it could be delivered in German, but only if all attendees are German speaker.

IS IT POSSIBLE TO ASK SPECIFIC QUESTIONS AT THE TRAINING?

Yes. Specific questions will be collected at the beginning of the training and during the training an will be discussed during training or towards the end of class.

QUESTIONS ON CONTENT

IS THE SLIDE'S CONTENT THE SAME AS DAN LINSTEDT'S CONTENT?

Yes. All slides are the same. The only differences result in the fact that slides evolve over time. But all trainers are using the same slide decks.

IS BI-TEMPORAL MODELING COVERED IN THE CLASS?

Yes. The training covers bi-temporality with temporal PITs. In case of doubt, such questions will be handled on the white board.

DOES THE COURSE COVER THE INTEGRATION OF BIG DATA TECHNOLOGIES (HADOOP)?

Yes. The course covers hybrid architecture and Hadoop as a PSA (Persistent Staging Area), real-time and IoT. Furthermore, the application of Hive for Raw Data Vault will be discussed.

QUESTIONS ON CLASS MATERIALS

WHERE CAN I GET SSIS DATA VAULT TEMPLATES?

There are templates for Microsoft SSIS Packages in the book Building a Scalable Data Warehouse With Data Vault 2.0. But predefined templates don’t always make sense, because the loading process is dependent on the data base infrastructure.
