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.

AZ-300 course experience was good . Eylem Uysal was very good, the best instructor and i had really good experience attending course and classes with Eylem.

This was my second course through ExitCertified, and it continues to be a great way to learn and advance my career!

Instructions were clear, lab exercises were pertinent and self-explanatory, topic was thoroughly covered in the presented course material.

Great training that provided pro-tips a plenty that were immediately put to use.

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