Which of the following statements about Entities is false?

The statement regarding entities that is false is that they do not require an identifier. In OutSystems, as well as in most database systems, entities must have a unique identifier, often referred to as a primary key. This identifier is crucial as it allows for the distinction between different instances of an entity and ensures data integrity within the database.

Entities are designed to represent real-world objects or concepts and consist of attributes, which capture the properties of those objects. The ability to create, update, and delete entities is a core functionality of OutSystems, allowing dynamic data management in applications. Additionally, stating that entities are only stored in memory is misleading, as entities are typically persisted in a database rather than being limited to just memory resident data.

Therefore, the need for an identifier is fundamental to the purpose of entities in maintaining unique records and facilitating proper data operations.
