Create an SQLite Database as follows: A table called “Product” with the fields: _id, Name, StockOnHand, StockInTransit, Price, ReorderQuantity, ReorderAmount. StockOnHand – this represents how many of a Product is currently in the Warehouse/Store. StockInTransit – this represents how many of a Product has been ordered and is on its way, not yet received. Price – this is the cost of a Product. ReorderQuantity – this is the number at which stock levels must reach before a purchase order must be made. If StockOnHand is less than ReorderQuantity + StockInTransit, then a purchase order is necessary. ReorderAmount – this is the amount to be purchased when a reorder is made.
