The Domain schema holds Smart Instrumentation domain data, managed by the Domain Administrator and engineers. The software creates the Domain schema when the System Administrator initializes a domain. The System Administrator is prompted to define the Domain schema name and password and the defined Domain schema name becomes the domain logon name in the database. In Oracle or SQL Server, the System Administrator can encrypt all the Domain schema logon passwords in the database if needed. When performing a database connection, the software retrieves the logon name and password from the PROJECT table of the Admin schema.
