I want to see the database schema but I am beginner in Zope and this framework. Thanks
There is no such a “database schema” in ZODB, a native object database for python. The most similar thing to a “traditional” relational table would be a catalog, but this is not useful to know the entities and their relationship. If you want to know what are the fields and relationship among entities in senaite, you should look directly to the python code.
For instance, this is the code for the content type AnalysisRequest (that represents a Sample).
From line 139 onwards, you can see the “attributes”/“fields” this class comes with, as well as their relationship with others, if any (e.g. the allowed types for field “Contact” are objects from type Contact)
