We aim to develop the "Inventory Control" application for Ocean Tanker's bunker barges to control the bunker master list items. In version 2.0 of "Inventory Control" application, it is to handle the quantities of oil sample bottles and sample cubitainers. And it also support to make the material request to restock the bottles and cubitainers. In this version (2.0), there are two types of user roles. The first one is administrator role that can make the material requisition procedure. The another one is the operator that can update and view its own stocks.
