Is this supposed to be a question?
A schema is a collection of database objects, including tables, views, indexes, and synonyms.
Every email address is something like this ... <u>[email protected]</u>
the name after the @ symbol is a domain name that represents the administrative realm for the mail box and the part before the @symbol identifies the name of the mailbox.
<u>twrigley(local portion)</u>@ gumchewer.biz(domain)
twrigley is the local portion which indicates to the mail server which mailbox the message is from or to.This portion is only important to gumchewer mail server which is why it is called local.
I say it is true
hope this helps!
