Anywhere, and you can't forget equally functional but less vigorously marketed products, such as Computer Associates OpenIngres and Desktop editions, Inprise Interbase, and many more. We started by looking at the basic functionality of the DBMSs. We wanted to store a reasonably large volume of product and shop data, which we needed to access quickly, and hopefully capture a huge volume of online transactions. Product data is not as straightforward as it seems. Products are categorized in different hierarchies, depending on the type of shop you host.
Different products have different attributes.
For a pizza, you can request a collection of toppings from a list, while for a dress you select one size, and one color, also off a list. But for customized stationery users must provide their own address, logo and slogan. Data in this day and age is rarely restricted to text and numbers. Of course all the relational DBMSs provide for basic relational constructs, such as tables, views, and indexes. However, we found that only Interbase had implemented domains properly.
