What are the different types of database indexes?
An example of an AI chatbot conversation about index types in databases.
What are the different types of database indexes?
There are several types of database indexes, including B-tree, hash, and bitmap indexes. Each serves different purposes.
Can you explain B-tree indexes?
B-tree indexes are balanced tree structures that maintain sorted data and allow for efficient insertion, deletion, and search operations.
What about hash indexes?
Hash indexes use a hash table to quickly locate data based on a key. They're great for equality searches but not for range queries.
When should I use bitmap indexes?
Bitmap indexes are ideal for columns with a low cardinality, like gender or status, as they use bitmaps to represent data efficiently.
