I would like to become hyper-excellent in SQL programming, query optimization, relational database design with UML, database administration…. Being just excellent, I bought an entire library on these matters… I start to learn temporal databases. Having extensive experience with relational database systems and being open-minded, I am able to easily adapt to any business and to any RDBMS. By the way, as (almost) everybody, I have a preference for PostgreSQL.
My job of a SQL programmer and my learning of jewish religious laws go well together. Instead of trying to dissimulate that I am an orthodox jew, I dare to try a synthesis between traditional hebraic logic and modern information technology. I find my inspiration in the books about logic, language and communication written by Moshe Chaim Luzzatto, a scholar of the 17th century, and modern mathematical logic.
My commitment to the relational model
Despite the hype about NoSQL models, I stay committed to relational model because :
• It is a matter of fact that the relational model absorbs concurrent models
• Very robust relational databases are used since years by a lot of people
• PostgreSQL, the most powerful of relational databases, is open-source
• NewSQL databases are very fast
• SQL is a good implementation of the Predicate Calculus which is
• the language of mathematics since 100 years
• the formalization of aristotelian logic, the model of rationality since 2300 years
• SQL is used even on NoSQL databases
I live in Antwerp. I am a database developer and administrator working with Linux and PostgreSQL. I have a one person company : Michel Depiesse Consulting. While studying higayone – the hebraic logic – I deepen my knowledge of SQL, relational theory, Entity-Relationship model, UML, mathematical logic…
I lived in Brussels. I got degrees in IT and I worked for years in big companies. Have a look on my resume. After some years with C and Perl programming and Unix administration, I worked with databases as administrator, developer and designer with Oracle and SQL Server. I learned the relational model and I enjoyed it because I love logic since my early youth. At the age of twelve, I had an awesome mathematics teacher who taught set theory, propositional and predicate calculus, truth tables, boolean algebra…
