For example, if there is a use case to make a room booking, there must also be computation rules to determine the room charges.
例如,如果有一个用例是进行一个房间预订,也必须有一个计算规则来确定房间费用。
Note, not all products have related association rules, as the support of the rules may have been too small during computation.
请注意,不是所有的产品都有相关的关联规则,因为这些规则的support在计算过程中可能会过小。
Constraints (e.g., a payment cannot exceed a certain value) and derivation rules (e.g., the computation of interest), especially when these are relevant to more than one use case.
限制因素(举例来说,一个支付不能够超过一个特定的数值)和推导规则(举例来说,利息计算),尤其当这些不仅仅与一个用例相关时。
