Hi everyone,

I’m a new member, I find out a datahub app in Legato (/legato/apps/sample/dataHub) and I have several question :

- what dataHub app for ? I searched information about it in the internet but just have code without explanation clearly about any feature as well as how to use or test it
- Have anybody ever try with these features and code sample ?

If you know about it , please talk to me, thanks you so much.
