Quizplus · Accepted Answer

A relation is a table that stores data. The order of the columns is not important, but the column names and their data types are. The order of rows is also unimportant, as the data can be sorted or filtered in various ways. However, each row must have a unique identifier, such as a primary key. Entities in a column should be of the same kind to maintain data integrity. It is not recommended to use the same name for multiple columns as it can create confusion and errors.
