Space management

Warehouse : A physical space where we put inside items.

• items, located in bins
• bins, where items are located
• halls, where are bins located
• actions, importing or exporting items from the bin

Warehouse Management System (WMS)

Principle

We have to know where(1) we have stored(3) (in which exact place) which item and how many of them(quantity)(4)

1. item, a thing that is going to be stored in the bin, consist's of a id(usually its bar-code, char(13)), name, description
2. where the item has been stored, referred as bin , so as a result we have to map the space with bins, consist's of id(usually identified by a bar-code, char(13)), address, name, description
3. record or transaction of importing, exporting, referred as action, consists of id(uuid), type(Import, Export), itemId(char13), binId(char13), userId, quantity(int). we have to check when type is import if there is a quantity to export, else rollback.

Functionalities

• crud operations for the basic entities, e.g item, bin, hall
• service for finding an item (where it is located), returns bin
