The difference will depend on your configuration and master data, if any. You control this (mainly) by how you setup your catalogs (see this link) and your offering subscriptions (see this link or this link).
The purpose of technical vs business catalog is in short to differentiate what is offered to providers vs consumers. A vanilla consumer may as for access or support, but typically would not be allowed/able to ask for a specific change to be pushed from migration to production environment. The exact differences are derived from how you design your technical and business services.
