What are the main algorithms used in RDMBS ?
The most common is
B-Tree
http://en.wikipedia.org/wiki/B-tree
A very complex topic. B-tree is just one of the algorithms; it is a binary algorithm used to find records quickly.
Here are some others:

SQLite is a good database to study because the code base is very small and much easier to understand than the bigger ones.

Im searching for numerical algorithm realization for nonlinear equations system solver on PHP, C, C++, Java (with readable code :). Where I can find them?
Thx.
Look in Numerical Recipes -- the latest edition has reasonable C++ code. Even if they don't have code to exactly solve your specific application, there's a good chance they have something you can use.

I am looking for an aggregated summary of comparison of popular data structures. Kind of one place where i can see all the data structures with their complexities, advantages and disadvantages.
http://en.wikipedia.org/wiki/Comparison_of_data_structures
It compares a few of them, but there are a lot of different structures.

Like the 20Q, is there a published algorithm that allows a program to "learn" from user input?
Programs like junk mail filters learn from what you tell it and uses that information to make more insightful choices in the future when classifying an email as junk.
Mahout is one open source machine learning library. It has implementations of a few different algorithms

I have to cluster a list of jobs using fuzzy c-means optimized by the ABC Algorithm. any example of applying those algorithm together ??
thank you very much in advance for helping ...
ABC is used to optimize the FCM algorithm I'm working on a project in the same field and i found this helpful FCM ABC

I have a big database of jobs, each job has numerical and non numerical attributes like(position,field,salary, needed experience...)
and applicants to jobs that determine some attributes like(age, expected salary...)
I want to create an application that do automatic matching between the jobs and the appropriate candidates*What is the best Algorithm to apply (data mining or artificial intelligence) to implement this app.*
thx for your replies
It seems that what you want is a recommendation algorithm, not matching algorithm.
There is not best recommendation algorithm which work for all cases. You should look into several algorihms and select which suits best for your situation. I recommend you to look at Apache Mahout which implements lots of such recommendation algorithms and is an open-source library.
