I have an entity that has many-to-many association to itself.
If I needed some additional properties (like asked here ) the answer would be to use a new intermediate entity. But without them is it bad practice to use direct many-to-many association to the entity itself?
使用映射表是N对N关系的最佳方法,而无需在映射表中自行创建新列。
Aleksey,
If you have additional columns, you need a new intermediate Entity .
But without them is it bad practice to use direct many-to-many association to the entity itself ?
No, you can if you want since you do not have additional columns on The joined Table
