Data Modeling

Course review
9 Reviewers


This is not just a database design course, but covers concept modeling with business people, architecture-type modeling, and extensive, enterprise-level data modeling. Extensive modeling can also be done quickly and efficiently – with the right methods and organization.

Ari Hovi and his team have developed a unique method for this – the Hovi Data Framework, which models business information quickly and as comprehensively as possible. It creates a common language between the internal IT, data professional, consultant and business. Utilizing it will greatly increase the probability of projects succeeding.

The exercises in the courses use the easy-to-use Ellie modeling tool we developed that works in the cloud. This further enhances learning through practice.

The course covers a wide range of concepts and data modeling in different areas: business data modeling, modeling required in data architecture, modeling leading to a database, and in brief also modeling methods related to data warehousing. Includes universal concept models developed by Ari Hovi to speed up modeling.

Data modeling, or conceptual analysis and description, are important methods and are needed in many different information management processes. It is necessary to describe top-level business-oriented overall models, more specific application-specific models, and the models needed for database design. Thus, models are developed for many purposes and it is important to be able to create accurate and also top-level overall models. We also deal with unstructured, Big Data modeling.

Modeling produces data or concept models. But moreover, modeling is at its best a synergy collaboration where participants share their views, learn and – what is important – commit to the project. Modeling defines important concepts, creating a common language and vocabulary between different parties, at best across organizational boundaries.

To whom this course is suitable:
The course is suitable for architects, those involved in modeling, project managers and supervisors. The course is also important for individuals who read or apply models already made, such as application designers, programmers, and ETL and report implementers. No prior information requirements.

Training times:
9: 00-16: 15

The structure of the course:

In the course, we will become familiar with the many description methods and methods of modeling and provide practical guidance on both top-level “helicopter image” models and accurate models and specifications. We also review the data warehousing area modeling methods for EDW stock design (including the introduction of the Data Vault model) and the principles of star model design. Plenty of hands-on exercises and examples deepen learning.

“Ari Hovi’s Data Modeling course was inspiring and engaging! Modeling teaches you to look at things in a data-centric way and can provide important insights to circumvent data management pitfalls such as duplication and data silencing. I recommend the course because data modeling is a collaboration for which learning through doing is very well suited.”
Aini Mlläri, Consultant, Capgemini Finland Oy

“A clear and practical close-knit course that made understandable an issue that is often perceived as awkward. Provides a good overall view of the topic and verifies the usefulness of modeling in many areas from database design to understanding the company’s operating models. ”

“I am very pleased with the company-specific Data Modeling training I received from Ari Hovi. Trainer Minna Oksanen Tailored the training to suit us and I heard good feedback from the participants. Participants were divided into small groups with different levels of participants and all learning from each other. There was a lot of exercise involved and learning happened all the time. As a whole, I would say “Money well spent”.
