An Entity identifier in OutSystems is defined as what?

An Entity identifier in OutSystems is indeed created by default with a Long Integer data type and is set as Auto Number. This means that when you create a new Entity in OutSystems, it automatically generates a primary key for that Entity, which is crucial for uniquely identifying each record within that Entity. The Long Integer data type is suitable for this purpose, allowing for a wide range of integer values that can support a large number of records.

The Auto Number feature ensures that each new record gets a unique identifier automatically assigned by the system, which simplifies the management of unique records and enhances data integrity. This automatic handling of unique identifiers is particularly beneficial when working with multiple records, as it reduces the risk of duplication and manual errors.

This understanding of Entity identifiers is foundational for managing data in OutSystems, as it establishes how data relationships are maintained and accessed effectively in the application.
