alias or nodenumber

[Paul van Beukering]

As an end user of MMBASE I would like feedback on the following situation:   I make a site for users playing several type of games. All game results are put in a result object. Now, I would like to make the following relation: usernode - resultrel - result resultrel tells me which type of game was played for a user. I hesitate to use a nodenumber as field in resultrel, I would say it's better to use an alias of a gametype as resultrel field? Am I correct and can I just use a string field for alias as resultrel field?   Thanks in advance, Paul
