Best Practices for Database Creation - Teradata Database

To ensure data integrity, Teradata recommends that only administrators and high-level users have the privilege to access data tables. All other database activity should be done in views.

Teradata recommends that you create top-level databases to separate tables and views. You can create additional lower-level databases within the top level databases as required by site security policy and user access needs.

Database	Description
Tables_Database(s)	Owns perm space. Contains all tables and data. Normally accessible only to privileged administrative and batch users for: Creating and modifying database objects Performing data loads and updates
Views_Database(s)	Requires minimal perm space because it does not contain data. Contains views of the tables in the Tables_Database. Exists primarily to provide SELECT access to the data for all users. Note: Where security policy requires it, you can designate a layer of views for load and update operations so that even batch users do not need to directly access data tables.
