@---+ DatasourceService
|
|
|
|
A DatasourceService is a webservice with a single AccessPoint giving access to a single source of related data. This is very often equivalent to an access service to a database or a subset of it. But important is that all its data is interrelated.
|
|
|
|
Each datasource can be represented with several ConceptualSchemas, thus the relation of the data is required.
|
|
|
|
The following things apply to a datasource:
|
|
* It is the end point of a message trace and therefore cannot relay any more messages. It therefore needs no destination in its header.
|
|
* It has always only a single response with a single source of data
|
|
* It is the entity where paging takes place
