The building block of a database is the
record. A record is a collection of related data treated as a single
entity. For example, a hockey trading card could be called a record:
it brings together the name, photograph, team, and statistics of one
player. Using database terms, each of these related pieces of information
is called a field: each hockey card “record” has a name
field, a photograph field, a team field, and various statistic fields.
A collection of records that share the same fields is called a
table because this kind of information can easily be presented in
table format: each column represents a field and each row represents
a record. In fact, the word column is synonymous with the word field,
and the word row is synonymous with the word record.
A database can contain more than one table, each with a unique
name. These tables can be related or independent from one another.
