Data Modeling (BA35)

In this class, business analysts will get hands-on practice modeling requirements through entity relationship diagrams, super- and sub-types, and attributive and associative entities.

Course Outline

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.

• How logical data models relate to requirements
• Identifying entities and attributes
• Determining relationships and business rules
• Data integrity through normalization

Note: We had 2 different trainers during this 3 day course. Course: Terminology should reflect North America and be consistent with our business lingo.

Found the course very informative. I had little exposure to Sharepoint and learned a number of things I didn't know. Plan to take the next level of training

The course is so expensive to be payed by oneself. In almost all the others participants their companies pay the fee.

Course was very detailed but more time would be helpful during workshops. An additional day would help lessen the course load.

The course was very relevant. I was able to apply the knowledge I aquired in the course to my job on the very next day. The only complaint I have is with the temperature of the room. It was freezing! Students has to wear a jacket or sweater. We were told the temp gage was shared with another classroom that was quite warm so they had turned the temp very low causing our room to be very uncomfortable.

Given the cost of the course, the hardcopy of the manual should have been provided. It would have been useful to make notes alongside the material as we went along.

I am very disappointed with the handouts. I was told I could go online and download a copy of the manual, the problem is that I would like the printed copy of the manual. I chatted online with one of your technitian who was unable to help me. Then I was told someone would contact me by phone to help me. That never happened. When taking a training course, a person EXPECTS to leave the course with ALL the material.
