An OmniScript needs to fetch and combine data from several sources and apply server-side logic before a step displays. The consultant wants to keep the client light and make one server call. Which element is the best fit inside the OmniScript?

選択肢

1. Several separate Data Mapper Extract actions chained on the client, one per source, and this is assumed to hold regardless of the data volume or the user's context.
2. A Calculation Matrix, because it fetches and merges data from multiple systems.
3. A FlexCard embedded as the data-fetching engine of the step, so.
4. An Integration Procedure action, which runs the combined server-side logic and returns the result in a single call, keeping a read.
