Hi All,
We are considering BASE as the molecular diagnostics backend system for a
project, and I was trying to figure out some of the backend workings of the
schema. I would appreciate some feedback on the following:
1) Is there a document that explains the PG schema that BASE uses, as far as
the role of each table, and how it fits in the global model for BASE?
2) Is there an instance of BASE which includes a comprehensive project that
shows the meaningful use for the database?
At a more detailed level:
3) Patients/Subjects are entered as Biosources (from the web front end), and
are saved in the BioMaterials table. Samples from these subjects are added as
Samples (from the web front end) and are saved in the same BioMaterials table,
too. Same for extracts. To relate these entries together, one can make use of
the parent_id column and the discriminator level (i.e. 1, 2, 3). Is this
explanation accurate?
4) Is there a way of entering/saving that a specific sample has been
analyzed/complete?
5) The number in the column event_type in the BioMaterialEvents table, what
does it reference?
6) Where is the sample type saved in the database?
Thanks for your feedback.
