OData $expand Query Option
The OData V4 model in SAPUI5 supports automatic determination of $expand and $select, a feature that automatically computes the necessary OData query options based on the data bindings defined in the application. A developer uses this to avoid manually specifying which properties and navigation properties to request, reducing boilerplate and helping ensure that only the required data is fetched. This contributes to overall performance optimization by minimizing the amount of data transferred from the server.
