Why is the following query valid for a NATURAL join? SELECT album.title, artist.name FROM album NATURAL JOIN artist;     The two tables share identical columns. The tables have a shared column, but their column names are not identical which makes it a candidate for a NATURAL JOIN. The query is not a valid NATURAL JOIN query and must use a JOIN... ON instead. The tables do not have a foreign key relationship.

Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.
