A relationship is an important component of a relational database. A relationship exists between two tables when one or more key fields from one table are matched to one or more key fields in another table. The fields in both tables usually have the same name, data type, and size. It also helps to further refine table structures and minimize redundant data.
The purpose of a query is to retrieve information from a table or tables, which can be based on some type of criteria. To put it simply, a query is designed to get you an answer from data already stored in the database.
I think a few of the most important concepts in a relational database design are: Primary Key (PK) - A column with a unique value for each row. From a design perspective a PK is a requirement. Primary Keys allow you to quickly and easily associate data from multiple tables that are related. Foreign Key (FK) - When you want a row in one table to be linked to a row in another table, you place a FK column in the child table and use the value of the parent row's PK as the value of the FK field.
