Table Collection of data in a structured format, in columns and rows.

Table SQL

Primary Key A field in a table which uniquely identifies each row/record in a database table. Primary keys must contain unique values and can not have NULL values.

Foreign Key A foreign key is a key used to link two tables together. The relationship between 2 tables matches the Primary Key in one of the tables with a Foreign Key in the second table.

View A view is a SQL statement that is stored in the database with an associated name. A view is actually a composition of a table in the form of a predefined SQL query. A view can contain all rows of a table or select rows from a table. A view can be created from one or many tables which depends on the written SQL query to create a view.

Cross Reference Table Table used between two other tables to associate multiple line items to a single item.
