Bob is an excellent tutor and helped me to understand important foundational concepts in Data Warehousing and SQL queries. Bob went above and beyond by locating and discussing additional reference material that helped illustrate key advanced SQL query examples such as SQL ROLLUP and CUBE. I will seek out Bob as my tutor for anything related to SQL and Data Warehousing.
There are many tutors out there, but there are some of them that stand out from the rest. I have had two SQL lessons with Barry and he has demonstrated that he has authority in the area of SQL. Barry has really impressed me because he is patient, reliable, and for the most part, he has excellent communication skills. I want to state here that I have no doubt recommending Barry as a tutor because he is an outstanding person in the field of SQL.
John is smart and an excellent tutor. He has been helping me on an database SQL project for several weeks now. The thing that impresses me most is his ability to quickly think through problems when the answers are not always straight forward. Another quality is his patience and encouragement to guide me through the process so I can understand at my level. Without hesitation, I can highly recommend John as your SQL teacher.
