Q
What are the key principles of SOA?
A
- Service contract: services adhere to a communications agreement, as defined collectively by service description document.
- Service loose coupling: services maintain a relationship that minimizes dependencies and only requires that they maintain an awareness of each other.
- Service abstraction: beyond descriptions and the service contract, services hide logic from the outside world.
- Service reusability: logic is divided into services with the intention of promoting reuse.
