Topic: Wine StoreDatabase

*)SystemRequirements:

Before we built the wine store, our client told us what it should do and what features they wanted.

Let's take a look at the scope and aims of the wine store that would typically be gathered from

interviews, studying workflow, and so on.

The wine store sells wines from wineries that are located in regions throughout Australia. The wine

store is open to the public: anonymous users have limited access to the application, and users can

make purchases if they become members.

The wine store carries thousands of wines, and the details of each wine include its name, vintage

(year of release), the winery that makes it, grape varieties, and, in some cases, an expert review of

the wine.

The wine store doesn't do much more than manage members, wines, and ordering. It doesn't have

a reporting module, an administration interface, or any content management features. It is not

designed to be a fully functional application but only to illustrate most of the fundamental

techniques discussed throughout the book.

*) Explanation:

The wine store model can be summarized as follows:

A customer at the online wine store purchases wines by placing one or more orders.

Each customer has exactly one set of user details.

Each customer has a title (such as "Mr." or "Dr") and lives in a country.

Each order contains one or more items.

Each item is a specific quantity of wine at a specific price.

A wine is of a type such as "Red," "White," or "Sparkling."

A wine has a vintage year; if the same wine has two or more vintages from different years, these are treated as two or more

distinct wines.

Each wine is made by one winery.

Each winery is located in one region.

Each wine has one or more grape variety entries. For example, a wine of wine name "Archibald" might be made of the grape

variety entries "Sauvignon" and "Cabernet." The order of the entries is important. For example, a "Cabernet Sauvignon" is

different from a "Sauvignon Cabernet."

Each inventory for a wine represents the on-hand stock of a wine. If a wine is available at two prices, there are two

inventories. Similarly, if the stock arrived at the warehouse at two different times, there are two inventories.

Each wine may have one or more inventories.
