Multiple values in lookup fields
i have a table has about 27 fields are just strings and every one of them have multiple values for example itemType Field have more than 10 possible values and the user may insert more
i made a tables called properties with those fields (Id, Key, Value) to store those values but now i'm confused wither i should use just the (Id)s and reference them in the original table (i think it's no good to put 27 relationships) or doing something else which i don't know what is it exactly
any better ideas or is it ok to continue like this
thanks
