使用SQL和Linq（实体框架/实体）的多对多关系

Question

I have two tables:

- Attendees
- Events

Normally, I would create a mapping table ' EventAttendeeMap ' to link these tables into a many to many relationship.

Is this the best way of doing so? Should I store the list of AttendeeId s in an xml column instead on the Events table?

I am using .NET 3.5/4 with Linq as the DAL (although I think this is irrelevant to the design question being asked, possibly).

Interested to see what people's opinions are.

Thanks. Dave

Answer 1

映射表绝对是最好的方法 - 实体框架将映射表转换为两侧的实体集合，表本身将基本消失。

Answer 2

In short yes - create a mapping table to hold the event id and the attendee id.

There is a good question here that might be of interest to you.
