10 Questions
What is the basic difference between ordered indices and hash indices?
Ordered indices store search keys in sorted order, while hash indices use a hash function to distribute search keys across buckets
What is a clustering index in the context of ordered indices?
A clustering index specifies the sequential order of the file and is also called a primary index
What is the purpose of an index file in the context of database management?
To speed up access to desired data by providing a lookup structure based on search keys
What is the key feature of hash indices in distributing search keys across buckets?
Uniform distribution of search keys using a hash function
What access type is efficiently supported by ordered indices?
Records with an attribute value falling in a specified range of values
What is the key difference between ordered indices and hash indices?
Ordered indices store search keys in sorted order, while hash indices use a hash function to distribute search keys across buckets.
What is the purpose of an index file in the context of database management?
To speed up access to desired data by providing a structure for efficient lookup of records based on search keys.
What is a clustering index in the context of ordered indices?
An index whose search key specifies the sequential order of the file, also known as a primary index.
What access type is efficiently supported by ordered indices?
Access to records with a specified value in the attribute.
What is the key feature of hash indices in distributing search keys across buckets?
Using a hash function to uniformly distribute search keys across buckets.
