Encryption
Encrypt the entries in sys.syscomments that contain the text of the CREATE VIEW statement.
Schema binding
Bind the view to the schema of the underlying table or tables.
View metadata
Specify that the instance of SQL Server will return to the DB-Library, ODBC, and OLE DB APIs the metadata information about the view, instead of the base table or tables, when browse-mode metadata is being requested for a query that references the view.
Check option
Force all data modification statements executed against the view to follow the criteria set within select_statement.
