I'm confused about when to use indexes in my database. I know they can improve query performance, but I also heard they can slow down data insertion and update. So, I'm wondering when is the right time to implement indexes.

When dealing with databases, it is crucial to optimize the performance of queries by utilizing indexes. Indexes are particularly useful when selecting or ordering data based on specific columns.

The WHERE clause is commonly used in SQL queries to filter rows that match specific criteria. By indexing the columns referenced in the WHERE clause, the database can quickly locate the relevant data, reducing the time needed to execute the query.

Similarly, the ORDER BY clause is used to sort the results of a query in a specified order. Indexing the columns used in the ORDER BY clause can significantly improve the sorting speed, as the database can utilize the index to arrange the data efficiently.

However, it's important to note that while indexes can enhance query performance, they also come with a cost. Excessive indexing can slow down write operations, such as inserts, updates, and deletes, as the database needs to maintain the integrity of the indexes.
