Final answer:
The two databases can be used together by combining relevant data to create the webpage for the art store's sale items.
Step-by-step explanation:
In order to create the webpage for the art store's sale items, the two databases can be used together by combining the relevant data from both databases. This can be done by matching the item names in both databases and retrieving the necessary information such as prices, categories, number of items in stock, sales prices, and sale dates. By using the data from both databases, the webpage can display the items for sale, their prices, the sales prices during the sale period, and any other relevant information.
Grouping the data differently could involve organizing it by category or sale date. This can provide advantages such as easy navigation for users who are interested in specific categories or who want to browse items on sale during a particular period. By switching between tables, if necessary, it allows for the retrieval of specific information, such as combining the items' prices, number of items in stock, and sales prices during the sale period.
