|
||||

|
||||
maintaining the database and for offering ad hoc query facilities to users and
|
||||
applications.

== Views ==
|
||||
|
||||
A database view is a subset of a database and is based on a query that runs on
|
||||
one or more database tables. There are essentially named queries.
|
||||
|
||||
=== dynamic views ===
|
||||
|
||||
dynamic views can contain data from one or two tables and automatically include
|
||||
all of the columns from the specified table or tables. They are automatically
|
||||
updated along with data in the source tables
|
||||
|
||||
=== static views ===
|
||||
|
||||
static views contain data from multiple tables and and the columns from said
|
||||
tables are included via SELECT and WHERE commands.
