The correct command sequence to create a compressed backup of a MySQL database, including all tables and data, is:

mysqldump -u username -p'password' mydatabase | gzip backup.sql.gz

Here's the step-by-step explanation:

1. `mysqldump -u username -p'password' mydatabase`: This command is used to create a backup of the MySQL database. The `-u` option specifies the username, and the `-p` option specifies the password. The name of the database is provided at the end.

2. `|`: This is a pipe operator, which is used to pass the output of one command as input to another command.

3. `gzip`: This command is used to compress the output of the `mysqldump` command.

4. ` backup.sql.gz`: This part of the command is used to redirect the output (which is the compressed backup of the database) to a file named `backup.sql.gz`.

So, this command sequence first creates a backup of the MySQL database, then compresses it using `gzip`, and finally saves it to a file named `backup.sql.gz`. This approach is efficient and secure because it minimizes the amount of data that needs to be transferred and stored, and it protects the data by requiring a username and password to access the database.
