Very good presentation, Pablo.
Very good for people studying the possibilities, good study, good
evaluation of the databases.
I was missing the MarkLogic database, which is expensive to use ($18.000
a year, or $0.99/hr on Amazon AWS), but can be downloaded for free for
developers:
http://developer.marklogic.com/free-developer
I appreciate if someone can publish experiences with this database. It
is document-centric: native XML, JSON and NoSQL.

Hi Fadoua,
I would suggest to consider generating a DB schema from the
information model rather than generating it from the archetypes, since
the schema for the IM can store any archetyped structure without
modifying the schema, and with the approach you proposed, your schema
will grow with each new archetype.
Also measuring performance is tricky, because performance will depend
on specific use cases, and some schemas might be more performant for
insert intensive usage, and others will be more performant for
querying intensive usage. Event two different schemas on the same DB
technology might have different benchmark/performance results on
different use cases. Also optimizations can be done, and as more
indexes are defined (more redundant data), performance for querying
can be improved a lot, even using a relational database.
You might already consider this but it's worth noting: most of the
current relational databases support XML or JSON as primitive
datatypes. It might be interesting to test those also as an
alternative of a native document database.
I've been working on this area for awhile, and a couple of years ago I
designed the openEHR clinical database implementation course (in
spanish, english available soon), and presented a workshop with other
members of this community for the MEDINFO, it was the workshop with
most attendees of the conference 😊here you can find the presentation:

BTW, did you considered testing openEHR backends? If yes, please take

Unique. Currently there is no other system that for openEHR clinical
data storage, that has a secure REST API and is open source.

*Subject:* Converting Archetype into Nosql Schemes
Thanks everyone for you help i will take into consideration your notes
As for making my goal more clear for Eric, i would like to combine my
Openehr archetypes with different nosql schemes ( document oriented,
colomn oriented and key/value) in a sense of comparing the performence
of storage and processing of these models with openehr standard.
because (till now there is only the comparison of couchbase with SQL
relational databases and no focus on specific nosql schemes)
so by then i can select the optimal solution to include as a
performant model and do some analytics with datamining techniques and
here goes the process of my whole phd goal.
My regards,
Fadoua khennou
