Sabre technologies can be accessed in a Tier 1 layer (a web/presentation layer) that offers such capabilities as configuration management, session management, and cache management.
Digital Connect builds a set of state of the art services that allows a presentation layer entirely created by the Airline. Using Digital Connect, Airlines can
- build native applications
- integrate external content
- cross-sell features
The Digital Connect API allows an access to Tier 1 services, as shown in the following diagram:
The following principles guide the architecture of the Digital Connect API:
- Uniform interfaces – the API provides an interface between client side and server side that simplifies and decouples the architecture. This enables the client side and server side to independently evolve.
- Client/server relationship between Digital Connect Services and their users – as long as the interface is not altered, this allows for both client side and server side actors to be independently developed and replaced.
- State management on the server side – state management enables greater flexibility since the server will be maintaining, updating, or communicating the session state.
- A layered system – adherence to the preceding principles facilitates the use of intermediary (hardware) servers which further improve system scalability by enabling load-balancing and providing shared caches. It would also facilitate enforcement security policies.
- Cacheable – caching eliminates client/server interactions and thus, further improves scalability and performance.
