What Is SQL?
Unlike other languages (spoken languages such as English, or programming languages such as Java or Visual Basic), SQL is made up of very few words. This is deliberate. SQL is designed to do one thing and do it wellprovide you with a simple and efficient way to read and write data from a database.
What are the advantages of SQL?
DBMS-Specific SQL Although SQL is not a proprietary language and there is a standards committee which tries to define SQL syntax that can be used by all DBMSs, the reality is that no two DBMSs implement SQL identically. The SQL taught in this book is specific to MySQL, and while much of the language taught will be usable with other DBMSs, do not assume complete SQL syntax portability.
