Step-by-step explanation:
Company ABC should use a database to maintain an electronic record of client anniversaries.
A database is a structured collection of data that can be easily accessed, managed, and updated. It provides a more efficient way to store and retrieve information compared to other options like a spreadsheet or physical calendar. With a database, the company can create a table to store client information, including their anniversary dates, and set up queries and reminders to send anniversary cards on the appropriate dates.
Furthermore, a database allows for flexibility and scalability as the company grows and acquires more clients. It can handle large amounts of data and is designed to efficiently handle updates and queries, ensuring accurate and timely reminders are sent to clients.
