Description: The index range refers to a specific set of index values used in queries within databases. This concept is fundamental for optimizing query performance, as it allows database management systems (DBMS) to access data more efficiently. By defining an index range, developers can specify an interval of values they wish to query, reducing the amount of data the system needs to process. This is particularly useful in large databases, where searching for information can become slow and resource-intensive. Index ranges can be applied to various types of data, including numbers, dates, and text strings, and are a key tool in creating SQL queries. Additionally, using index ranges can improve the readability and maintainability of code, as it allows developers to clearly express search conditions. In summary, the index range is an essential component in optimizing database queries, facilitating faster and more efficient access to stored information.
