The MySQL Literacy benchmark measures your knowledge to create databases and tables and perform simple insert and query operations. You will be evaluated on your skills in modeling entities and relationships in a real-world scenario, translating to MySQL tables with the correct column specifications, and inserting and updating data in those tables. A learner who scores high on this benchmark demonstrates that they have the skills to work with a MySQL database, write queries, use sub-queries and date utilities, and utilize pattern matching with wildcards and the LIKE operator.
