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.
Bob helped me to understand the concepts of SQL having a tight project deadline. We also went into a complex query that I started to modify based on my project needs. He was very patient and structured in terms of explanation and the sequence of the material. I definitely recommend Bob to anyone who needs to have a solid foundation of SQL and build on top of it.
