What are the recommended data types for Session Variables?

Session Variables in OutSystems are specifically designed to store data that needs to persist across multiple requests within a user's session. The recommended data types for these session variables primarily include Basic Types and Entity Identifier Types.

Basic Types encompass simple data types, such as integers, text, and booleans, which are ideal for straightforward session-related data. Entity Identifier Types are crucial for storing references to specific records in the database, allowing for seamless management of user states that are tied to the data entities within the application.

Using these types ensures that the data stored can be efficiently managed, retrieved, and manipulated as users interact with the application. The other types mentioned—like Complex Types—could lead to unnecessary complexity or performance issues if used as session variables, as their structure could complicate access and storage during a user's session. Therefore, the focus on Basic and Entity Identifier Types aligns with best practices for session management in web applications developed using OutSystems.
