in this example it is having two keys, then how many children it is having, so each node can have maximum 3 children. so this is three ways search tree. 3-way ST. each node has M (3) children, so how many keys M

For example, the order=2 B-tree illustrated inFigure 7-1has tree pointers: to child nodes whose value is less than the first key, to the child nodes whose value is greater than the first key and less than the second key, and to the child nodes whose value is greater than the second...
example • We want to insert the following indexes into an empty B+-Tree of p=3 and p leaf =2 –8, 5, 1, 7, 3, 12 • Initially you start with the root node which is of type leaf node (no children yet) 5 8 * *

Below is an database index Example of Sparse Index Secondary Index The secondary Index in DBMS can be generated by a field which has a unique value for each record, and it should be a candidate key. It is also known as a non-clustering index. ...

The present Concurrent B-Tree system and method do not prevent the option of using nested top actions where part of a transaction persists after a rollback. Nested top actions are typically used with structural modifications. (An example of a nested top action is found in Mohan, et al., "...
