3.2. UML Diagrams¶

3.2.1. Overview¶

An overview of this inventory system is illustrated by the following UML diagrams.

For more information about UML diagrams, please see any of these links.

3.2.2. Scan QR Code¶

$@startuml (Warehouse\nInventory\nSystem) as (Use) User -> (Scan QR Code) User --> (Use) note right of (Use) The response from the Warehouse System determines the next screen presented. end note note as N3 Label includes a QR code and a box number. end note (Scan QR Code) .. N3 N3 ..(Use) (Use) .. (New Box) (Use) .. (Existing Empty Box) (Use) .. (Existing Filled Box) (New Box) .. (Checkin) (Existing Empty Box) .. (Checkin) (Existing Filled Box) .. (Checkout) (Existing Filled Box) .. (Move Box) (Existing Filled Box) .. (Consume Box) @enduml$

3.2.3. Checkin¶

$@startuml (Warehouse\nInventory\nSystem) as (Use) User -> (Checkin) User --> (Use) note right of (Use) See the Checkin Sequence Diagram for the steps for checking a box into the inventory system. end note note "User has filled, sealed and labeled a box." as N2 (Checkin) .. N2 note as N3 Labels include a QR code, the product, year of expiration and optionally the part of the year (e.g. quarter it expires) end note N2 .. N3 N3 ..(Use) @enduml$

Checkin Inventory Use Case¶

$@startuml User -> SmartPhone: Activate QR Code Scanning Application User -> SmartPhone: Scan QR Code on box SmartPhone -> Website: Lookup the QR Code URL Website -> Database: Request box information Website <- Database: Return box information Website <-- Database: or create empty box record\n and return it Website -> SmartPhone: Present (usually) empty box info User -> SmartPhone: Enter product User -> SmartPhone: Expiration year\n(maybe partial year) User -> SmartPhone: Box location User -> SmartPhone: Touch checkin button SmartPhone -> Website: Send box information Website -> Database: Store information entered Website <- Database: Return confirmation SmartPhone <- Website: Present confirmation User <- SmartPhone: User verifies confirmation visually @enduml$

3.2.4. Checkout¶

$@startuml (Warehouse\nInventory\nSystem) as (Use) User -> (Checkout) User --> (Use) note right of (Use) See the Checkout sequence diagram for the steps for checking out a box of inventory. end note note "User finds a box containing product to be removed from inventory" as N2 (Checkout) .. N2 N2 ..(Use) @enduml$

3.2.5. Move Box¶

$@startuml (Warehouse\nInventory\nSystem) as (Use) User -> (Move box) User --> (Use) note right of (Use) See the Move box sequence diagram for the steps for checking in a box of inventory. end note note "User has new location information ready" as N2 (Move box) .. N2 N2 ..(Use) @enduml$

Move Box Use Case¶

$@startuml User -> SmartPhone: Activate QR Code\nScanning Application User -> SmartPhone: Scan QR Code on sealed box SmartPhone -> Website: Lookup the QR Code URL Website -> Database: Request box information Website <- Database: Return box information Website -> SmartPhone: Present (usually) filled box info User -> SmartPhone: Touch move box button SmartPhone -> Website: Send request to move box Website -> Database: Send request to move box Website <- Database: Retrieve box info and return SmartPhone <- Website: Present box info and\nnew location blanks User <- SmartPhone: Display box info and\nnew location blanks User -> SmartPhone: Verify box information and\nenter new location User -> SmartPhone: Touch update box\nlocation button SmartPhone -> Website: Send new box\nlocation information Website -> Database: Send new box\nlocation information Website <- Database: Return new box\nlocation confirmation SmartPhone <- Website: Display move confirmation User <- SmartPhone: Visually confirm move @enduml$

3.2.6. Fill a Pallet¶

$@startuml (Warehouse\nInventory\nSystem) as (Use) User -> (Checkin) User --> (Use) note right of (Use) See the Fill Pallet Sequence Diagram for the steps for checking a pallet into inventory. end note note as N2 User has filled, sealed\n and labeled a number of boxes and wants to put them all on a pallet. end note (Checkin) .. N2 note as N3 User has also decided what location in the warehouse that the palled will be placed once the boxes have been loaded on the pallet and checked into inventory. end note N2 .. N3 N3 ..(Use) @enduml$

3.2.7. Move a Pallet¶

$@startuml (Warehouse\nInventory\nSystem) as (Use) User -> (Checkin) User --> (Use) note right of (Use) See the Move Pallet Sequence Diagram for the steps for moving a pallet from one location to another in the inventory system. end note note as N2 User has filled, sealed and labeled a number of boxes and wants to put them all on a pallet. end note (Checkin) .. N2 note as N3 User has also decided what location in the warehouse that the palled will be placed once the boxes have been loaded on the pallet and checked into inventory. end note N2 ..
