Final answer:
If you frequently sort on a field, it is a good candidate for creating an index in a database. Indexing improves the performance of searches and sorting operations.
Step-by-step explanation:
If you frequently sort on a field, it is a good candidate for creating an index in a database. Indexing is a technique in databases that improves the performance of searches and sorting operations. When you create an index on a field, the database engine organizes the data in a specific order, making it faster to retrieve and sort the data based on that field.
For example, imagine you have a database of students and you frequently need to sort the students by their grades. By creating an index on the 'grades' field, the database can quickly retrieve the students in the desired order without having to scan the entire dataset.
Overall, indexing can significantly improve the efficiency of sorting operations in a database, making it a good choice when you frequently need to sort data based on a specific field.
