Data modeling is a set of techniques that are fundamental to the processes of understanding, designing, implementing, and curating data. Despite the many declarations that “data modeling is dead” it continues to be an essential part of effective data management. Data Modeling is not dead, but the practices of data modeling are different today than in the past.
Once the domain of database designers and developers, data modeling is now an important skill for data engineers, data scientists, data analysts, application developers, and data curators. Modeling for traditionally structured data is now extended to encompass the variety of big data and NoSQL data types. Semantic data modeling simplifies data integration and is essential to achieve data interoperability. In today’s data modeling practices, long-standing modeling techniques are combined with new and different techniques to adapt to variety in data and data management use cases.
This 4 hours 45 minutes course teaches practical data modeling skills ranging from traditional relational modeling to key-value, document, graph, and semantic data modeling.
