attribute vs element definition



Hi

I am getting confused as to what is the difference between an attribute
and an element. People seem to use the terms all over the place. I
googled it and it seems that attribute is the correct term. I had
someone even say that attribute are groups of elements ... Anybody know
of a definitive site for the nomenclature?

PHYSICAL DATABASE

AddressTable <--- ENTITY
myKey
streetAddr1 <--- ATTRIBUTE / ELEMENT ?
city

ER-DIAGRAM

AddressTable <--- ENTITY
myKey
streetAddr1 <--- ATTRIBUTE / ELEMENT ?
