Databases are a way to store data and its relationships, and access it over a
|
|
|
|
|
network, with caching and other optimizations.

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.
