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 -- Cordialement, *KHENNOU Fadoua * *________________________________________________**_**_**_**_**_**_* *Phd student at USMBA-Fes, Morocco * *Transmission and Processing of Information laboratory * *______________________________________________**_**_**_**_**_**_**_**_*
