B-Tree Index B-tree index is the widely used data structures for tree based indexing in DBMS. It is a multilevel format of tree based indexing in DBMS technique which has balanced binary search trees. All leaf nodes of the B tree signify actual data pointers. Moreover, all leaf nodes ar...
In fact, as I'll demonstrate here, a bitmap index on a culumn with 100-percent unique values (a culumn candidate for primary key) is as efficient as a B-tree index.In this article I'll provide some examples, along with optimizer decisions, that are common for both types of indexes ...

Systems like MD-HBase [16] are using this technique to work with such data. MD-HBase is a multi-dimensional extension of HBase, which allows the efficient storage of two-dimensional points. A K-D Tree or a QuadTree partitions the space, and linearization is employed to generate ids for...
