Stefan Ardeleanu

Stefan Ardeleanu is a (relational) database specialist. He is not a DBA but a SQL developer. He has experience in many systems but mainly in Oracle and SQL Server, although he was involved in various projects using PostgreSQL or DB2. As a SQL programmer, is this job still necessary on the market after so many years of existence? This is one of the questions that worries Stefan. He has been doing this for over twenty years and is still passionate about what he does.

Stefan is also a former teacher and an Oracle trainer. This qualification means that he also knows how to explain what he does and he really likes it in addition to being an excellent data programmer. On the other hand, Stefan likes to write. He graduated in both Mathematics and Philosophy, developing both spiritual sides. His style is not excessively technical, even if so far he has only written SQL books.

His opinion is that programming is part of life. The (SQL) developer tries to implement concrete aspects of the world and, precisely because of this, the style of explaining the various programming techniques is accessible and natural. Stefan strongly believes that a SQL book can be enjoyable and intelligible even by a business analyst, project manager, tester, or even application user. In some places, even by a person who may not work in IT.

Stefan is Romanian, born in Bucharest in 1967. He has experience in many projects in the field of databases, he is an independent contractor, and now he lives in Luxembourg. Stefan has his own small company, called suggestive Simply SQL. Stefan believes the way we write SQL is critical to the performance of many IT systems, and he promotes the set-based approach style of development as the essential ingredient.
