Final answer:
True statements in relation to platform scripting are that UI Actions can execute both client-side and server-side (B), UI policies are only enforced on data entered through the user interface (D), and Client Scripts execute on the browser and may involve server interaction for database lookups (E).
Step-by-step explanation:
In relation to platform scripting, there are several statements that can be evaluated for their truthfulness. First, we must consider the functionality of business rules, UI Actions, data policies, UI policies, and client scripts.
Business rules can indeed be real-time and can monitor fields on a form to enforce logic on the data within the platform's database. Therefore, statement A is false.
UI Actions have the ability to execute both client-side (in the user's browser) and server-side (on the server hosting the platform). This makes statement B true.
Data Policies are not meant to run as UI policy client-side; they enforce data consistency and correctness on the server side. This makes statement C false.
UI policies are implemented to dynamically change form information and are indeed only enforced on data entered into a form or list, which aligns with statement D being true.
Client scripts, which generally execute on the browser, may necessitate a server-side trip, typically to perform a database lookup or other server-side logic. This makes statement E true as well.
Therefore, the true statements in relation to platform scripting are options B, D, and E.
