Views

A view is a logical way of looking at data from one or more tables in the database. A view is a "virtual" table that does not actually exist in the database. A view contains pointers to the actual tables in the database. Views can be used to include a subset of information stored in one or more tables, while leaving out other information. Views are part of normal SQL Server functionality.

To make it easier to query data from some of the AVEVA Historian tables, a number of views onto the data are provided. Queries are performed on these views as if they were normal physical tables.

Note: Some views are included in the database for backward compatibility support only. It is recommended that you discontinue the use of these views, as they will be dropped in a future release. For details about views retained for backward compatibility, see Backward Compatibility Views.
