In computer science and database management systems, a s data structure]] is a fundamental concept. A record is a collection of related s or s that stores information about a particular entity. Each field or attribute within a record holds a specific . The is a unique identifier that allows efficient retrieval and identification of the record. The value represents the data associated with the record.
To optimize search operations, an is often used. An index is a data structure that enables fast access to records based on a specific field or attribute. One way to implement an index is by using a , where each node contains a pointer to the record. Another approach is to use an that stores the key-value pairs in a sorted manner, facilitating efficient searching through binary search algorithms.
Alternatively, a can serve as an index structure. A binary tree is a hierarchical data structure consisting of nodes, where each node has at most two child nodes, left and right. By organizing the records in a binary tree based on the key, retrieving a specific record becomes significantly faster as only a fraction of the tree needs to be traversed.
