This lab illustrates the use of indexes and EXPLAIN to optimize query performance. Refer to EXPLAIN documentation for information about EXPLAIN result columns.
Write and run seven SQL statements:
Explain the query SELECT * FROM film WHERE title = ‘ALONE TRIP’;.
In the EXPLAIN result, column key is null, indicating no index is available for the query. Column rows is 100, indicating all rows are read. The query executes a table scan and is slow.
Create an index idx_title on the title column.

Evaluating Internet Sources
The Internet has been called the world’s biggest library, but unlike library material, Internet material is not always subjected to rigorous editorial procedures. Never has the adage been more true than when applied to the Internet: “Don’t believe everything you read.”
Choose a website and evaluate it according to the three criteria discussed in Chapter 7 for evaluating Internet sources. Be sure to provide a link to the site and include the criteria in your main post.
View the Medical Robots Speech. Identify the main points of the speech and the supporting materials used for each. Evaluate the speaker’s use of supporting materials in light of the criteria discussed in Chapter 8. Be sure to incorporate the criteria in your main post.
