Definition - What does B-Tree mean?
A B-tree is a type of tree, or data structure, that helps support various IT systems by allowing a range of dynamic child node numbers that can be changed over time. It uses a set of keys to divide these collections of nodes.
Techopedia explains B-Tree
In general, trees are abstract data types (ADT) that enable the specific ordering of node collections in order to convert data into more accessible formats.
One benefit of the B-tree format is that developers can rebalance data on a less frequent basis. Other benefits include improved data access efficiency for large sets of information. Database administrators can use tools like indexing to improve functionality and various algorithms to assess time of access in specific setups.
