Description: The Min-Max index is a data structure used in databases to optimize the performance of SQL queries, especially those involving ranges of values. This type of index stores the minimum and maximum values of a specific column, allowing database engines to perform searches more efficiently. By having direct access to the data limits, the system can quickly discard data blocks that do not meet the search criteria, thus reducing response time and processing load. Min-Max indexes are particularly useful in columns containing numerical or date data, where queries often require searching for ranges. Additionally, their implementation can be more space-efficient compared to other types of indexes, as they do not require storing all individual values, only the extremes. In summary, the Min-Max index is a key tool in SQL query optimization, enhancing the speed and efficiency of search operations in databases.
