Sierra D. - I had the privilege of being a student in Dr. Cecelia Allison's Introduction and Intermediate to SQL course, and I am about to start the Advance SQL course. The course materials were very clear, well-organized, and easy to use. Going into the course I was scared because I’m a visional learner. Dr. Allison made it so easy with her step-by-step presentation videos and reading material. I said to myself I had this course in the bag. I must say that she is a phenomenal instructor, and I would recommend this course to anyone wanting to learn SQL. Also make sure to check out her YouTube Channel.



Kakungulu E. - I had the privilege of being a student in Dr. Cecelia Allison's Introduction to SQL course, and I must say that she is a phenomenal instructor! Dr. Allison's course materials were not only well-organized but also incredibly clear and easy to use. Her teaching style is engaging, making complex SQL concepts seem accessible and manageable.

Dr. Allison's YouTube channel greatly enhanced my SQL skills through engaging video examples and lectures. Her optional exercises and attentive participation in discussion boards further enriched the learning experience. If you're new to SQL or want to improve your skills, I wholeheartedly endorse learning from Dr. Allison.



Daniel J. - Dr. Allison is a great instructor! Her course materials were clear and easy to use. I gained a lot of insight from her video examples and lectures. After taking her Introduction to SQL course, I feel confident in my beginning SQL skills as she provided ample opportunity to practice and extend my learning. I especially appreciated her optional exercise assignments, which served as a personal check to see that I had mastered the content. She is really attentive to the discussion boards and offered very helpful clarification and additional resources that I found very helpful. If you are new to SQL or want to sharpen your skills, I definitely recommend taking a course from her.



Marcia R. - I took Dr. Allison's online course. It was very well-designed, building up from foundational information to more complex items. There were numerous hands-on query practice exercises, which really allowed one to learn the material. After completing the course, I feel confident that I understand enough to begin writing queries and putting the knowledge into practice. Thank you, Dr. Allison!



Kauzy Y. - I took Dr. Allison's SQL courses. Dr. Allison is an outstanding instructor and learning facilitator, who makes complex information easy to absorb, and is always an available resource when clarification is needed. I am now a key management resource in my department for all things "SQL". I also purchased her book, "SQL Simplified:", and use it constant source in real world medical data retrieval scenarios. Great teacher, great author!



Jane N. - Dr. Allison was the Course Developer and On-line Professor of the SQL Certificate that I completed.

I started the course with working knowledge of relational databases but did not have any experience in programming or querying using SQL. I was out of my element when I did the first unit in the Introduction to SQL. I felt as though I had stepped into a totally different world.

Dr Allison assured me that I would be OK and that I needed to just take my time to understand. Every time I had questions or difficulties understanding concepts, I would post it in the discussion area. Dr Allison always responded quickly to my questions with thoughtful answers to help my understanding.

I have now completed the SQL course. I have learned so much and have confidence in my skills. Without Dr Allison’s support and excellent materials (reading materials, online presentations, quizzes and discussion areas), I would not have completed this course.

Instruction was the BEST I have ever had in the online learning community. I will take any other course that Dr Allison is offering online because I know I will receive the attention and information I need to be successful. Thank you again.

Thanks, Ms. Allison!



Jose R. - I have taken multiple courses in SQL with Cecelia. I recommend her as and instructor, and plan to continue learning through her myself. Course objectives we clearly defined and always met.
