I read this on wikipedia: In B-trees, internal (non-leaf) nodes can have a variable number of child nodes within some pre-defined range. When data is inserted or
I was looking at the best & worst case scenarios for a B+Tree (http://en.wikipedia.org/wiki/B-tree#Best_case_and_worst_case_heights) but I don\'t know how to use this formula with the information
In MySQL, an index type is a b-tree, and access an element in a b-tree is in logarithmic amortized time O(log(n)).
First of all you should already 开发者_Go百科know MyISAM index doesn\'t include the actually data, it only has the address of data.
It seems when new node is inserted(whose complexity is O(logN)), the whole tree needs to be r开发者_如何学Pythone-balanced.
I\'m investigating the possibility of putting together a custom storage scheme for my application.It\'s worth the effort of potentially reinventing the wheel, I think, because both performance and sto
I am trying to construct an m-way tree and I am having trouble visualizing an array of pointers pointing to different instances of the B_tree node class (this basically creates the array type nodes an
What is the complixety of turning a sorted 开发者_如何学编程array of size n to a legal 2-4 B tree?
iv\'e implemented a B+tree , my leaf nodes point to start of line(record) positions in a CSV file , my question is :
I am wondering how the oncoming SSD technology affects (mosty system) programming. Tons of questions arise, but here are some most obvious ones:
