Within busby a resource group is a structured set of persistent data - think of it as a database with tables and rows.
Resource groups are made of resource types, which define a set of fields - and the links between those resource types.
Individual records within a resource type are called resource ids.
So we have the following relationships.
Resource groups are served by a Resource Group Service, which is a busby microservice that handles the operations on that group - eg adding, reading and searching of resources.
Resources are useful in lots of places within busby systems - anywhere that it is useful to have persistent structured data a resource might be appropriate. For example
There is an in built selector application that can be configured to allow for resource viewing and editing, for simple use cases this might be all that is needed.
