Which of the following describes a key benefit of indexing in a database?

A significant advantage of indexing in a database is that it dramatically increases the speed of read actions. When a database uses an index, it creates a data structure that allows the database management system to find data without scanning every row in a table. This is particularly beneficial when dealing with large datasets, as it can drastically reduce the amount of time required to retrieve specific records. Essentially, indexes serve a similar purpose to an index in a book; they point to the location of specific information, allowing for quick access without needing to read through all the content sequentially. This efficiency is crucial for optimizing performance in applications that rely heavily on database queries.
