Final answer:
The art store's website requires information from both databases to display all needed sales information, with items for sale serving as the common linkage. Option 4 is correct, integrating both databases searched by the items for sale to provide comprehensive details.
Step-by-step explanation:
To create the sale items page for the art store's website, it is necessary to consider the available databases and how they can be integrated to display all the required information. The first database contains the items for sale, the regular prices, the categories of each item, and the number of items in stock. However, to present sales-specific information such as the sales price and the dates of the sale, the second database is indispensable. Therefore, the correct approach would be to use both databases together to aggregate all the needed information.
The best method to integrate data from both databases and display complete sales item details on the website would be option 4: "Both databases are needed, and each database can be searched by the items for sale to display all the information on the website." Each item for sale serves as a common key to link the data across both databases, ensuring that users can see the categories, the regular and sales prices, as well as stock availability and the duration of the sale for each item.
By leveraging both databases, the website will be able to present a comprehensive view of the sale items, which is essential for a user-friendly shopping experience. Effective data integration and web design principles can help present the information in ways that are not overwhelming to the customer and enhance the usability of the site
