What system is used to store all customer-related data within an organization?

The system primarily used to store all customer-related data within an organization is Customer Relationship Management (CRM). A CRM system is specifically designed to manage a company’s interactions and relationships with potential and existing customers. It enables organizations to streamline processes, improve customer service, and enhance customer satisfaction by organizing customer information, tracking interactions, managing leads, and analyzing data related to customer behavior.

Unlike the other options, a CRM focuses on customer interactions and data. For instance, an Enterprise Resource Planning (ERP) system integrates various business processes across departments like finance, supply chain, and human resources but does not specialize exclusively in customer data. A Configuration Management Database (CMDB) is used to store information about the IT assets of an organization, including their configurations and relationships, rather than customer information. A Content Management System (CMS) is used for creating and managing digital content, such as websites and documents, which does not align with the specific needs of managing customer relationships and data.

Therefore, the primary function of a CRM directly correlates with the storage and management of customer-related data, making it the correct answer.
