## Overview

This repository is a SAP Core Data Services model for a space-itinerary company, with flight and space domain definitions, service definitions, and bundled table data. The likely user-facing workflow is booking or querying flight and space information through the services backed by those models. The README identifies the project as a base data model, but the CDS sources were not sampled, so service-to-model and data-loading relationships are shown as unverified rather than asserted as direct calls.

Main entry points: [`db/flight-model.cds`](https://github.com/sfroee/cloud-sample-spaceflight/blob/master/db/flight-model.cds) (Flight Model), [`srv/booking-service.cds`](https://github.com/sfroee/cloud-sample-spaceflight/blob/master/srv/booking-service.cds) (Booking Service), [`db/space-model.cds`](https://github.com/sfroee/cloud-sample-spaceflight/blob/master/db/space-model.cds) (Space Model), [`srv/flight-service.cds`](https://github.com/sfroee/cloud-sample-spaceflight/blob/master/srv/flight-service.cds) (Flight Service)
