Hello,
I have data model that is using Link Table ( my LinkTable is created by concatenation of common fields from tables): What are the best practices to add new table to the model?
Should I have master calendar in LinkTable or as a separate table connected to LInkTable?
Should I concatenate or join new table to one of former tables? or to LinkTable?
Should I create new appended key to connect new table to LinkTable? If I create appended key in new table, I need to have the same appended key in LinkTable in order to create connection. But what to do if I do not have that one of the field in appended key in LinkTable yet, or not available among other tables at all? If I pull another field from former table to link table in order to create appended key to new table, it will create synthetic key.
Thank you.
Best practice is to avoid link-table data-models by using a star-scheme.
