Designing Queries
Queries are incredibly useful and they are essentially used for searching for and compiling data from one or more tables. Using or "running" a query is a bit like asking a detailed and very specific question of your database. When you build a query in Access, you are defining specific search conditions to find exactly the data you want.
How are queries used?
Queries are far more powerful than the simple searches or filters you might use to find data within a table. This is because queries can draw their information from multiple tables.
