Since a business analyst needs to accurately elicit, define, and document user requirements, understanding the users' needs is key to an analyst's success. By using logical data modeling, a business analyst can convey requirements in a way that can easily be validated, and doing so allows stakeholders to understand the requirements, business rules, and data management methods for any given project.

In this class, get hands-on practice modeling requirements through entity relationship diagrams, supertypes and subtypes, and attributive and associative entities. You will learn to use logical data modeling to work directly with business users to accurately define requirements.

Students pursuing a university-recognized and/or accredited certificate in Canada or continuing education units in the US must attend at least 90% of class time, participate in class exercises and section-knowledge checks, and score at least 70% on an end-of-class, multiple-choice assessment.

Overall good experience considering the situation we are all in. Could use more hands on experience

Wow! Guaranteed to run training that is guaranteed to run! We were let down by a competitor of ExitCertified. Never again, we'll be using ExitCertified again and again.

Michael was amazing! Answered all our questions and went above and beyond when we need it, definitively really nice and friendly course. I'm pleased with the knowledge he had. Finally, I have finished the course having learned new stuff. Thanks, Michael!

ExitCertified did a good job in hosting this course. From the instructor to facilities. Good job!

It was a great class taught by Ruben. It was great the way he used his experience and use cases to communicate to the class.
