The purpose of having a structure inventory program is to make it easy for users to see what their inventory totals should be at. This will allow for better ordering and sales tracking. This type of program will be most ideal with businesses such as grocery stores, markets and gas stations. In order for this type of program to run smoothly there is certain information you will need to input to allow for accurate results. The type of information that will need to be gathered is starting inventory, which will involve accounting for what products are already there. The reason for this is because we will be adding and subtracting from this number to get our inventory, there is no way to keep track if you don't know the number of items you first started with. Keeping things items organized by categories will also help when it comes to doing audits and sales tracking because you can see what area is doing poorly, example categories would be medicine, drinks and candy. Now because some items differ by size and flavor, we would have to make sure we are accurately describing the item and labeling as exactly that. We wouldn't be able to count Coke and Pepsi together because they are different products, doing so lets us account for items more accurately. We also would have to distinguish from size since there are multiple sizes when it comes to items such as soda and candy. In keeping inventory under control, we would also have to determine the reasons for increased and decreased inventory levels. Increasing levels should only occur when receiving new merchandise, while decreasing can be due to sales, transfers, and theft. So there has to be a way to account for these items so that they are automatically adjusted. An example of how a selection structure for this program would be is as follows:
IF you buy one soda THEN inventory is reduced by one or else it stays the same. IF new inventory brought into the store THEN inventory will increase. IF two items are transferred to another location, THEN inventory will decrease. Selection structures involves having a certain situation or action that will bring on an outcome or response. PSUEDOCODE: IF items are sold THEN subtract amount from current total. ELSE leave inventory at it's current level.

IF merchandise is received THEN add amount to current total. ELSE leave inventory at it's current level.
