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 🙂

    One thing I’d like to say is always that car insurance termination is a feared experience and if you are doing the correct things being a driver you simply will not get one. Many people do obtain notice that they’ve been officially dropped by their own insurance company and several have to fight to get added insurance after having a cancellation. Inexpensive auto insurance rates are frequently hard to get after the cancellation. Knowing the main reasons with regard to auto insurance termination can help individuals prevent burning off one of the most critical privileges obtainable. Thanks for the strategies shared through your blog.

    An interesting discussion is definitely worth comment. I do believe that you need to write more about this issue, it might not be a taboo subject but usually people don’t speak about such issues. To the next! All the best!!
