How does Thingworx provide Data Segregation between clients in a multi-client environment?

I got this excellent question and I thought it worthwhile to put my answer here as well.

 

There are two ways to segregate information between clients.

By default we use a ‘software’ approach to segregation by using Organizations. This allows you to designate a Client to an Organization/Organizational nodes and give those nodes ‘visibility’ to specific entities within the software. This will mean that ‘through software logic’ users can only see what they’ve been given visibility to see.

This mainly applies to all the client’s equipment (Thingworx Things). They can only see their own equipment.

This would also apply to a specific set of their data which is ValueStream data because that can only be retrieved from the perspective of a Thingworx Thing

 

Blog/Wiki/DataTable/Streams can store data across clients and do not utilize visibility on a row basis, in this case appropriate queries would need to be created to allow retrieval for only a specific client.

In this case we use a construct for security that utilizes what we call the ‘system user’ and wrapper routines that work of the CurrentUser context, this allows you to create enforced validated queries against the data that will allow a user to only retrieve their specific data.

 

In regards to the data itself, if you need to, you can provide actual ‘physical’ segregation by using multiple persistence provider and mapping Blog/Wiki/DataTable/Streams/ValueStreams to different persistence providers.

Persistence providers are basically additional database schemas (in one and the same database or different database) of the Thingworx data storage schema, allowing you to completely separate the location of where data is stored between clients.

Note that just creating unique Blog/Wiki/DataTable/Streams/ValueStreams per client and using visibility is still only a logical / software way of providing segregation because the data will be stored in one and the same database schema also known as the Thingworx data persistence provider.
