Examples and Exercises
Most of the exercises that you encounter in this book use Oracle, a dominant leader in the market that adheres closely to the SQL standard but also offers many enhancements.
Oracle (as well as many implementations of SQL, or the relational database), make freely distributed versions of its database available. You can then select an implementation of your choice, install it, and follow along with the exercises in the book. Note that because these databases are not 100% compliant with SQL:2016, the exercises might have slight variations of the exact syntax suggested in the ANSI standard. However, if you learn the basics of the ANSI standard, you can generally translate your skills between different database implementations.
