All has started in 1990 after installing my first Oracle version which was Oracle 4 under SCO unix! It was a mess to install with a bunch of 3″1/2 floppies…
Since that day, I start to be passionate by data access algorithms. I remember a book that I still know by heart: The index-organized B-tree
During that period, I spend a lot of time learning c and c++ by implementing a database (that looks like Oracle from structure point of view) with:
-Buffer cache
-Simple SQL interpreter
I stop the project when I start to deal with rollbacks 🙂
