Database information
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. |
