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.
