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 搑ecord?has a name field, a
photograph field, a team field, and various statistic fields.
INTRODUCTION TO OUR COMPANY
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.
ABOUT
OUR SERVICES
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抯 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. |
