Which software package is best suited to keep track of customer data such as names, addresses, and purchasing history?

Database management software is specifically designed to efficiently manage large sets of data, including customer information such as names, addresses, and purchasing history. It allows for the storage, retrieval, and manipulation of data in a structured way, typically using tables. This software can easily handle relationships among different data sets and provide advanced features like querying, reporting, and data entry forms, making it ideal for CRM (Customer Relationship Management) applications.

In contrast, word processing software focuses on creating text documents and lacks the structure necessary for managing large amounts of data effectively. Spreadsheet software, while capable of tracking smaller sets of data, does not provide the robust functionality necessary for complex data relationships and can become cumbersome when dealing with significant volumes of customer data. Graphic design software is unrelated to data management and is intended for creating visual content rather than for tracking or storing information.
