/**
|
||||
* Service layer defines an application's boundary with a layer of services that establishes
|
||||
* a set of available operations and coordinates the application's response in each operation.
|
||||
*
|
||||
* Enterprise applications typically require different kinds of interfaces to the data
|
||||
* they store and the logic they implement: data loaders, user interfaces, integration gateways,
|
||||
* and others. Despite their different purposes, these interfaces often need common interactions
|
||||
* with the application to access and manipulate its data and invoke its business logic. The
|
||||
* interactions may be complex, involving transactions across multiple resources and the
|
||||
* coordination of several responses to an action. Encoding the logic of the interactions
|
||||
* separately in each interface causes a lot of duplication.
|
||||
*
|
||||
* The example application demonstrates interactions between a client (App) and a service
|
||||
* (MagicService). The service is implemented with 3-layer architecture (entity, dao, service).
|
||||
* For persistence the example uses in-memory H2 database which is populated on each application
|
||||
* startup.
