Let t be the degree of a BTree. Suppose the size of each object, including the key, stored in the tree is 90 bytes. Also, suppose the size of a BTreeNode pointer is 4 bytes. In addition, 100 bytes of meta-data is required for each BTree node to keep track of some usefull information. Suppose each BTreeNode has only the meta-data, a parent pointer, a list of objects, and a list of child pointers. What is the optimal degree for this BTree if a disk block is 4096 bytes?
Every big organization has large documents or databases containing data used in operating the business. Does a data warehouse differ from these operational files or databases?
Consider a queue data structure, where the two operations of interest are enqueue (at the back of the queue) and dequeue (from the front of the queue). A queue is thus a FIFO (first in-first out) structure. Suppose we implement a queue by using tw..
