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 ...

首先大家还是先来熟悉一下典型 B*tree 索引的结构图: 很明显,从图中我们可以看到: 1. 整个索引结构由root,branch,leafblock构成。 2. 从root block到每一个leaf block的高度都是一样的。 3. 索引条目总是是唯一的且在逻辑上是有序的。 4. 索引的扫描除了iffs(索引快速全扫描)总是单块读的形式。
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...

To do that we use Open API specification in version 3 that is compatible with most of the modern API tools like Swagger or Postman. Documentation file can be found in [Scada-LTS/doc](https://github.com/SCADA-LTS/Scada-LTS/tree/develop/doc/RESTAPI) directory. To take your first steps ...
