What is an example of a Transactional Database?

The example of a transactional database is aptly represented by the record of each retail transaction that a customer has made on Amazon.com. A transactional database is specifically designed to manage data that reflects transactions, capturing the details of activities such as purchases, orders, and sales. This type of database supports numerous transactions happening concurrently and allows for efficient retrieval and manipulation of transaction-related data.

In the context of Amazon.com, every retail transaction encompasses crucial information, such as the items purchased, purchase date, customer information, payment details, and more. This data is vital for businesses not only to track individual transactions but also to analyze trends, manage inventory, and enhance customer experience.

Other choices, while they represent various forms of data, do not capture the essence of transactional data. The records about career home runs, smoking status, or the number of bald eagles in a national park describe individual attributes or counts rather than dynamic transactions involving multiple data points that occur over time. Such records do not reflect a transactional pattern or would typically be housed in a different type of database, such as a relational or observational database.
