It is also possible to combine more than two strings into one string.
Two columns of the table may be used to store the strings that are to be combined, or they may just be stored individually without being stored into the table.
When the concatenated strings are stored in separate columns of a table, they are stored in the column in which they were initially stored.

Relational databases are required.
Databases contain a wide variety of information, and each row and column of each table must hold this information.
The primary key value, table name, and column name are characteristics that allow us to access the precise data (atomic value) logically from a relational database.
Null values are treated in database records according to this rule.
