What you’ll learn to do: Create and modify queries

Queries represent the most useful way we interact with a relational database. In this section, we will learn how to create basic and advanced queries in order to “ask questions” of the information stored in Access. Database queries can be as simple as “show me the top product line in XYZ territory this month” to as complex as “show me the lowest revenue stores in these five product lines in the top producing territories”. In either case, without queries relational databases would not be very helpful in running the business.
