 When the queries become more complex, it can be useful to add comments to express to yourself, or to others, what you are doing with your query. Comments help explain the logic of a section and provide context for anyone reading the query. It's essentially a way of making notes within your SQL. In SQL, comments begin using <code class="language-plaintext highlighter-rouge">\--</code> and end at the end of the line. To mark a whole paragraph as a comment, you can enclose it with the characters /\* and \*/. For example, a commented version of the above query can be written as:

 ## More Terminology
 
-The degree of relationship between entities is known as their 'cardinality'. Using the journals-publishers example, the 'publisheres' tble contains a primary key (PK) called 'id'. When the PK is used to create a connection between the original table and a different table, it is called a foreign key (FK) in the other table. To follow the example, we see a field in the 'journal' table called PublisherID that contains the values from the 'id' field in the 'publisher' table, connected the two tables.
