Mainframe, MVS and zOS Discussion

Hi,

What is 'Siblings' means in IMS. What is the difference between 'twins' and siblings in IMS DB. I read about it, however, it's confusing.

Hi Disha -



Siblings - Segments that share the same parent. Example : B,E1 and E2. C1,C2 and D. F1,F2,G and H.
Twins - Multiple segment occurrences that share the same parent occurrence. Example : E1 and E2, C1 and C2, F1 and F2.

Hope it helps.

Thanks Quasar - this was a nice explanation and helped me.

Thanks,
