Which of the following best practices should a developer follow when managing custom objects in Salesforce Commerce Cloud?

Limiting the number of custom attributes in each object is a best practice in Salesforce Commerce Cloud because it directly impacts performance, manageability, and clarity of your data model. When a custom object has too many attributes, it can become cumbersome to manage and may lead to performance issues when retrieving or processing data. A streamlined set of attributes not only improves the efficiency of database operations but also makes it easier for developers and stakeholders to understand and work with the object.

Moreover, maintaining a clear and concise schema allows for better scalability; as the system evolves, adding new features or changing existing ones can become more complex if objects are overloaded with attributes. Thus, keeping a limit on custom attributes encourages thoughtful design of data structures that can adapt to future needs without creating unnecessary complexity.

While organization scope can be useful in certain scenarios, it may not be appropriate for every custom object. Site-specific schemas also have their place but may not be necessary in every situation, particularly when broader accessibility is needed. Daily backups are crucial for data integrity but are more of a data management practice than a best practice regarding the design and management of custom objects. These considerations highlight the importance of thoughtful design in the development and management of custom objects within the SFCC environment.
