Help with Object Design
Can anyone assist me in my design?
Real world: I am a manufacturer of goods sold to a national retail chain. I have 10 different items in 1800 stores. Every week I get a report from the chain that shows inventory levels and # of purchases that week for each item, each store; 18,000 line on a spreadsheet. In Excel : I have a worksheet "Store List" which has all the information about the stores; Store number, address, regional info, etc. all pertinent info the chain uses to describe its stores. I have a worksheet "Product List" that has all info on each of the 11 items, SKU number, our part number, size, weight, cost, retail, description I have a worksheet "Sales Data" that contain a line for every store, every item... a reflection of the reports received from the chain with an inventory column, sales column, and on order column for each weeks report I receive. I transfer over the Inventory and sales data to a new column by hand. I have written many functions and acros to analize the data, but it is very inefficient. I would like to utilize classes to improve performance and ease of programming future improvements. So far I have: A store class: Describes any one store with all the store data from the "store list" worksheet An item class: Describes any one item A Product Line class: Which creates an array of 10 item classes Where should I store each stores sales and inventory data? Should "Qty on hand", "Quantity on order", "Quantity sold" all be private members of the item class? Should each weeks sales info be held in an array within the items class or the store class? Should the store class have an array of weekly product line snapshots? Should I be using a database? Should I go back to college? :) Any direction will be apreciated. Thanks |

It seems that you are trying to replicate capability that is embedded
in MS Access without the need for programming. You can probably execute your analytics with queries. And Access is a much easier way to track historical data. Have you considered migrating your database to that platform? SteveM Wired Hosting News wrote: Can anyone assist me in my design?
