yes. the user table must reference the sysid. and the sysid must be unique
in the computer system table.
some how or another the input data must make the association.
you could also have a unique name in the computer system table. then the
input data could say john doe uses computer xyz. the code that updates the
user table can extract the sysid from the computer system table based on
the name. then the user table is updated with the user name and the sysid.
