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.
A subset of data extracted from one or more tables is
called a recordset (or a DataSet in ASP.NET). A
recordset is also a table because it’s a collection of
records that share the same columns. For example, a
hockey team roster listing the names and positions of
the players could be called a recordset: it consists of
a subset of all the possible information about the
players, including goals, assists, penalty minutes, and
so on.
