Let me do the MultiParking Lot

  • So here my architecting would using up of the Multiple Parking Lots
  • A Parking Lot will have the Multiple Floors
  • A Floor has many lots.
  • Every Vehicles registration_number, vehicle_color, vehicle_intime, vehicle_outtime should be taken
  • The Bill Service basically is being charged based on what is the ParkingLot and then the what are the charges perhour for that particular parking lot perhour .
  • For my way desiging i had a overview of desigining the things from the base and i would love to keep it in as image .

Analysis

Approach1(I would have gone):

  • This is pretty much interesting like building the system i thought that there exists the parking lots that are multiple in number .

  • In doing analysis had no clue from where to start is it from top to bottom or from the bottom to top in building the class Models . Later concluded of boiling the problem down in the pattern of

ParkingLot,Floor,Lot,Vehicle and thought that this flow would make the things work and then started in this way

Approach2:

  • So i have started building the basic blocks from bottom to top approach first built the Vehicle model and then lot, Floor, ParkingLot model later.
  • This approach made me bit confusing to connect the dots
  • Probably if i would have done in an rspec way i should have started in the first approach way
