Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. It simply deducts a number from another number. Taking this course helped me understand who autowires objects into my classes :), Part 2- Identifying entities and figuring out the architecture and control flow of my service, I could assume that I had certain downstream services for validating my payment method, getting product prices from the database, etc, so I did not have to implement any DAO layer as such(or so I assumed from the requirements). Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
