What is the difference between a primary index and a secondary index?
Answer to relevant QuestionsIs it possible in general to have two primary indices on the same relation for different search keys? Explain your answer. Repeat as shown below for a B-tree.Construct a B+-tree for the following set of key values: (2, 3, 5, 7, 11, 17, 19, 23, 29, 31) Assume that the tree is initially empty and values are added in ascending order. Construct ...Why is a hash structure not the best choice for a search key on which range queries are likely?Assume (for simplicity in this exercise) that only one tuple fits in a block and memory holds at most 3 page frames. Show the runs created on each pass of the sort-merge algorithm, when applied to sort the following tuples ...Design sorting based and hashing algorithms for computing the division operation.
