   • Database Design: inventory and sales system?

     The solution you are looking for will rely on an accounting style model and a couple of bills of materials (BOM). Your major entity types will include:

     • SKU This is the list of things that you sell. It's properties will include things like product description and current retail price. You can get fancy and break price out into a child table that gives prices over time. Let's assume that you are going to leave that wrinkle out for now. Some SKUs can be "combos" of the sort you are talking about.
     • COMPONENT This is the list of things that make up a SKU, such as napkins, cups, buns, patties, coke syrup etc. - to use your example. Just as SKU has descriptions and prices, COMPONENTs have descriptions and unit costs. (Which can also be historized in a child table.) This table is where you would typically store your ROP too.
     • COMPOSITION This is a BOM which intersects SKU and COMPONENT and says how many units of each COMPONENT go into a unit of a SKU. You need one of these to intersect two SKUs too (for combos). You can either use one table or two tables for this. Two tables will keep the purists happy, one table will be expedient from a coder point of view.
     • SALE This is a transaction table that provides a header for recording a sale of one or more SKUs. This table would have things like transaction date, cashier ID, and other header items.
     • SALE_ITEM This is the transaction detail table that would include which SKU was sold (and how many) and for how much. The how much is a denormalization of the SKU price at time of sale, but could also include any special overrides to the price. The price actually charged for the SKU is a good thing to denormalize because someone could edit the list price in SKU and then you'd lose track of how much was actually charged for the item at the time.
     • INVENTORY_HDR This is a transactional table that is similar to the SALE conceptually, but it is the header for an inventory transaction, such as receiving new inventory, using up inventory (as in selling it) and for inventory adjustments. Again, this would be date/description stuff, but it can include a direct link to a SALE_ITEM for inventory movements that are sales if you like. You don't have to do it that way, but some people like to establish the connection between revenues and costs on a transaction by transaction basis.
     • INVENTORY_DTL This is the detail for an inventory transaction. This indicates which COMPONENT is going in or out, the quantity that went in or out, and the INVENTORY_HDR transaction that this movement applied to. This would also be where you keep the actual cost paid for the component item.
     • LOCATION You can (if you wish) also track the physical location of the inventory that you receive and use/sell. In a restaurant this may not be important but if you have a chain or if your restaurant has an offsite warehouse for component ingredients then you might care.

     Consider the following ERD:

     To do your revenue accounting you would be adding up the money recorded in the SALE_ITEM table.

     Stock levels are calculated based on adding up the INVENTORY_DTL ins and outs for each COMPONENT. (Don't store current stock levels in a table - This is doomed to cause reconciliation problems.)

     To do your cost accounting you would be adding up the money recorded in the INVENTORY_DTL table. Note that you won't usually know exactly which napkin or bun you sold, so it won't be possible to link specific component reciepts with specific SKU sales. Instead, you need to have a convention for determining which components were used for any given SKU. You may have accounting rules that specify what convention you are required to use. Most people use FIFO. Some industries use LIFO and I've even seen weighted average cost accounting.

   • Inventory design database with colors and sizes

     Don't store multiple values in one column in a relational database - it's generally considered bad practice.

     It would be better to have two tables, one with a product name and product ID, and another for variations (having columns variation_id, product_id, size, colour, quantity). The product_id column in the variation table will be a foreign key to the product table.

     If you don't know the relation between them, Just create two separate table for plant and nutrient with ID and later you can create a sub-table which can relate one plant with many nutrients and vice versa using their ID or how ever you want.

   • Database Design: Relationship example between Credit Card and Credit Card Type

     Top Answer

     Answered Sep 03, 2010 · 1 votes

     I would do it like this:

     Customer Id int-CreditCardType: Id int TypeName varchar (eg. Visa)CreditCard Id int CreditCardTypeId int CustomerId int CardNumber varchar

     Eventhough you could say that a creditcard type does not need an id since the TypeName is unique, it's better to have foreign key columns that are numbers since they take up less disk space. Imagine that you had a CreditCardType "American Express" which was the primary key of the CreditCardType, you would have to use that value in the CreditCard table for each row. If you have millions of registered credit cards it would take up quite some space to store the string for each row.

     I have seen both approaches at my current company and would definitely lean towards the first (calculating totals based on stock transactions).

     If you are only storing a total quantity in a field somewhere, you have no idea how you arrived at that number. There is no transactional history and you can end up with problems.

     The last system I wrote tracks stock by storing each transaction as a record with a positive or negative quantity. I have found it works very well.

     It depends, inventory systems are about far more than just counting items. For example, for accounting purposes, you might need to know accounting value of inventory based on FIFO (First-in-First-out) model. That can't be calculated by simple "totaling inventory received - total of inventory sold" formula. But their model might calculate this easily, because they modify accounting value as they go. I don't want to go into details because this is not programming issue but if they swear by it, maybe you didn't understand fully all their requirements they have to accommodate.
