Relationship cardinality in ERDs (1-1 relationships)
- One-to-one: 6.1 (implemented)
- Other types: 7.x or later
Currently (6.1) Dataedo ERDs support many-to-one and one-to-one relation types. We want to extend that with the ability to define cardinality at each end of relationship.
We want to make it in two stages:
- Stage 1 - support for one-to-one relationships
- Stage 2 - support for zero-or-more and exactly-one cardinalities of relationship ends
Please note it will not include many-to-many relationship types, as this kind of relation is not possible in physical data model (and Dataedo currently focuses on such models).
