Hello,

New big application in the shelves, which will be using Umbraco for all CMS stuff,
but it will also have to display lots of data from an external source (repository or wcf services)

This data will be readonly, no need to crud it from the backend.
In the front end, this ill be displayed through complex views (lots of fields, tabs, interactions)
Some search facility will be needed too.
I expect multiple thousands for records with lots of fields.

I can add custom models / controllers / views and plug this into Umbraco
(got it working this morning with Umbraco 7.13 and autofac, cool !)

or

I could image to somehow import this data into Umbraco nodes that would then join the standard umbraco workflow (import directly into the db with ssis, or through a custom coding to call umbraco api)

what solution would you advice ?

Did you get into the new stuff about properties / angular yet. Could it be of some use here ? 

Thanks a lot,

Luc
