He is credited with coining the term lasagna code and popularizing Michael J. Kamfonas' nested set model for trees in SQL, a taxonomy of data encoding schemes, and several other design patterns in SQL DDL and DML.

His commercial consulting work has been varied—auto loans, entertainment, aerospace, education, shipping (freight lines and ocean shipping), petro-chemical, software companies, and odd start-ups.

He has taught training classes in South Africa, Turkey, the UK, Norway, Sweden, Finland, The Netherlands, Brazil, Belgium and Switzerland. He has also created and taught on-line classes for MySQL and SQLUniversity.org. He was part of the founding faculty of Neumont University in Salt Lake City, a for-profit university for software developers.

Communication style

Mr. Celko is known for wearing trademark three-piece black suits with cuff links and putting on a good performance when he speaks. A well-known quote of his is "Columns are not fields. Rows are not records. Tables are not files," which has been put on tee-shirts.

There is a fan blog entitled JOE CELKO THE SQL APPRENTICE. This blog is not Joe Celko's but it is a collection of his answers in public newsgroups.

He has been an invited speaker at conferences and user groups in the US and overseas for decades. Celko has been a frequent volunteer speaker at SQL Saturdays in the United States in recent years.

His SQL books have continued to sell well and have been translated into Russian, Japanese, Chinese, French and Hungarian.
