of data access
... Adding element is preceded by the search algorithm and there is a need to insert a new value if there is no result of the search process. Then we know the side of leaf to which a new element is to be added. This adding can be without collision or can cause overflowing of page (if there are already 2 ...

... getting O(log m) access time and O(1) modification space and time. Here’s how they did it, in the special case of trees. In each node, we store one modification box. This box can hold one modification to the node—either a modification to one of the pointers, or to the node’s key, or to some other pi ...

S(b)-Trees: An Optimal Balancing of Variable Length Keys
... A search in an absolutely balanced tree is obviously logarithmic, since h = dlog2 ne. Unfortunately, in order to support the absolute balance condition while insertions and deletions a substantial reconstruction of the tree may be required such that the algorithms become linear rather than logarithm ...

What is link list???
... The above fig. is of a singly link list which also means a chain. A chain is a singly link list that is comprised of zero or more nodes.when the number of nodes is empty. The nodes of the non-zero(empty) chain are ordered so that the first link get connected to second and the second to the third and ...
