What are the different types of database indexing?
There are several types of database indexing, including B-tree, hash, and bitmap indexing. Would you like to know more about each?
Yes, please explain B-tree indexing.
B-tree indexing is a balanced tree data structure that maintains sorted data and allows searches, sequential access, insertions, and deletions in logarithmic time.
What about hash indexing?
Hash indexing uses a hash function to compute the address of data, making it very efficient for equality searches but not for range queries.
And bitmap indexing?
Bitmap indexing uses bit arrays to represent the presence of values, making it efficient for queries on low-cardinality columns.
