Imagine that you are developing your own website. Over time, there are more and more pages on it, the content continues to grow. To optimize work with a large amount of information, use databases. In turn, the databases themselves are also constantly changing and supplemented with new data. To simplify the process of administration, adding and editing information, special management systems (DBMS) have been developed. We found out earlier that MySQL is one of the many DBMS that are used to simplify the work with databases. It includes an internal server library with which you can use MySQL in standalone programs.
