Abstract: Services development/deployment for backend system integration includes metadata-based identification of assets of a backend system, and building metadata specifications as available constructs from which to develop services for deployment, each metadata specification corresponding to a given backend asset that uses a first data format and defining translations between the first data format and a second data format that is agnostic to selected service endpoints and endpoint deployment architecture(s) to provide agnostic development of the services, providing a development interface to a user, and obtaining a user-defined flow as a generic definition of a service agnostic to any specific service endpoint and endpoint deployment architecture on which the service is to be deployed.
