Basically a "query" is a way of asking the database a question, i.e.
How many people,
have a red car.
The query is set an can be a one off question or can be a question it is asked regularly.
The criteria is in effect the question you want answered i.e. how many people in you database have a red car So in the data base you may have the name, address, car type, car colour. In the colour field you would set the criteria as RED. Then running the query you will get all the cars that are red. If you then placed in the field on the database data about the type of car this could be Sports, saloon, hatchback SUV
So you can then ask red in the colour filed of the query and SUV for example in the TYPE field. It is the queries that make the database do its job of reporting back the information.
