How to search large database without SQL or alike. Just asking.
-
I am building a small database app on SAM3x8e hardware and decided that C++ will do. I basically need to find a matching record and have an idea how to do it. I don't see any timing issues. I was just curious how the "big boys" do search on VERY large database. I have heard about hash tables etc. OK, I can Goggle , but some pointers would be appreciated. Cheers Vaclav

I'm unclear on what you are asking. Are you using an existing database product? Or are you trying to create your own database system?

First part of that is basically incompatible with the second. In general the solution for your problem is similar in a very broad way in that one must: 1. Understand the data 2. Understand the searches needed. The solution(s) are then based on that. So for example it is pointless to use a hash if you are doing regular expression searches on free form text.
