Binary Search Indexing Database at Faith Sager blog

Binary Search Indexing Database. Binary search is a search algorithm used to find the position of a target value within a sorted array. A linear search on the id field would require an average of n/2 = 500,000 block accesses to find a value, given that the id field is a key field. That are, balanced search trees, not binary trees. The easiest solution is to sort the array and use binary search to find the value. Indexing helps databases swiftly locate and retrieve records, significantly speeding up query performance. Each entry in the index file corresponds to a block or page in the data file. In dense index has an index entry for every search key value in the data file. The index file contains pairs of primary key values and pointers to the corresponding data records. Searching start by selecting a value. But since the id field is also sorted, a binary search. It works by repeatedly dividing the search interval in half until the target. Whenever you insert a value into the array, it should maintain order.
