Cartesian product
In mathematics, specifically set theory, the Cartesian product of two sets and, denoted, is the set of all ordered pairs where is in and is in.

Column (database)
In a relational database, a column is a set of data values of a particular type, one value for each row of a table.

Database schema
The database schema is the structure of a database described in a formal language supported typically by a relational database management system (RDBMS).

Foreign key
A foreign key is a set of attributes in a table that refers to the primary key of another table, linking these two tables.

Join (SQL)
A join clause in the Structured Query Language (SQL) combines columns from one or more tables into a new table.

Null (SQL)
In SQL, null or NULL is a special marker used to indicate that a data value does not exist in the database.

Primary key
In the relational model of databases, a primary key is a specific choice of a minimal set of attributes (columns) that uniquely specify a tuple (row) in a relation (table).

Relation (database)
In database theory, a relation, as originally defined by E. F. Codd, is a set of tuples (d1,d2,...,dn), where each element dj is a member of Dj, a data domain.

Relation (mathematics)
In mathematics, a relation on a set may, or may not, hold between two given members of the set.

Relational algebra
In database theory, relational algebra is a theory that uses algebraic structures for modeling data, and defining queries on it with well founded semantics.

SQL
Structured Query Language (SQL) (pronounced S-Q-L; historically "sequel") is a domain-specific language used to manage data, especially in a relational database management system (RDBMS).

Table (database)
In a database, a table is a collection of related data organized in table format; consisting of columns and rows.

Tuple
In mathematics, a tuple is a finite sequence or ordered list of numbers or, more generally, mathematical objects, which are called the elements of the tuple.
