I started programming DOS Programs in C and C++ in the middle of the 90s right after being graduated. After my military service, the market was promoting B2B and B2C web site : I made bunch of them under Windev/Webdev EDI driving a 10 person team (all student or newbies) for various customers. Since 2000 I get closer DATA with massive use of ETL, SQL and Transac-SQL programs as a Project management officer.
