doubt about datum

Hi all, I'm new to postgresql programming and I'd like to understand what a datum is (what is its purpose); I guess it is a kind of OID for customized data type created by users, but I'm not sure. Moreover why it does not need transaction visibility as an ordinary tuple (xmin, cmin, cmax, xmax)? Thanks, Luca
