And you get this part somewhat for free if you're actually testing as you're going. When my service wants to store and retrieve as part of its behaviour, of course I'm going to back it with a hashmap first. Once I know it fulfills its business logic I'll start fiddling with hard-to-change stuff like DB schemas and migrations. And having finished and tested the logic, I'll have a much better idea of the actual access patterns so I can design good tables & indexes. |
