What is the difference btw "Order" and "Degree" in terms of Tree data structure
B-Tree Definition they use the 'order' term in :
According to Knuth's definition, a B-tree of order m is a tree which satisfies the following properties:
1. Every node has at most m children.
...
and 'Degree' is defined in Tree terms as:
Degree – number of sub trees of a node.
so, are they same thing? I cannot feel any difference.
Solution
Degree represents the lower bound on the number of children a node in the B Tree can have (except for the root). i.e the minimum number of children possible. Whereas the Order represents the upper bound on the number of children. ie. the maximum number possible.
