I have a table named Team. Each record can have more than one member. Rather than jamming members comma separated value, I am hoping to use separate table to meet the requirement. Id is primary key.

| 2   | TeamB | Micah

I thought of creating a table named User. UserId is the PK and TeamId is FK.

| 456     | Jack  |  1
| 789     | Micah |  2
