What is the major difference between regular Entities and local Entities?

Local Entities are specifically designed to operate within the mobile environment, and one of their primary characteristics is that they are meant to be used for data that resides only on the device. The limitation that Local Entities cannot be bootstrapped from Excel emphasizes that they are not intended for data that needs to be easily imported or exported in bulk like Regular Entities, which can be set up to pull data from external sources, including Excel files.

This distinction is crucial for understanding how data is managed differently on the device compared to a broader database environment. Regular Entities can leverage various data import mechanisms, including bootstrapping from Excel, which enhances data handling flexibility.

The other choices do not align with the core functionalities associated with Entities in OutSystems. Regular Entities are capable of managing complex CRUD operations while Local Entities are typically limited in this aspect. Additionally, Local Entities cannot be directly modified in the database as they operate within the confines of the app's storage while Regular Entities are meant for database interactions. Finally, it is not accurate to say that Regular Entities cannot store any data; in fact, they are designed specifically for data storage and manipulation in a database context.
