Difference between ThingWorx PostgreSQL(Thingworx comp) and ThingWorx Edge.
What is the difference between ThingWorx-Platform-Postgres-8-3-9(Thingworx composer) and ThingWorx Edge?
Also if i need to connect Thingworx composer to Mysql server should i use "ThingWorx PostgreSQL" or is there and other version ideally suitable.
