Notas del editor
- (Yes its Boring. But GOOD.)
- Web services can be used as building block to model business process. So different combinations/permutations of services would lead to different products from the same base services. This is the enabler of service oriented architectures.
- Machine machine communication over a network. Web services are designed to be consumed by applications.
- - Cost reduction – Infrastructure needed to run the service needs not be local. Maintenance is done by service provider - Provider can reach a wide consumer base with a relatively controlled infrasture Workflow engines help visualization of business process, pipelines Commercial and open-source workflow engines.
- Workflow engines may have a connection to a service registry,
- DDBJ – one of the three institutes that constitutes the DDBJ/EMBL/GenBank international nucleotide sequence database which was established through cooperation with EBI and NCBI
- - Which order this takes depends on how knowledgeable the user is about the service they are looking for.
- The WS-Reliability specification defines a method for exchanging SOAP-based messages with a particular level of quality of service, no duplicates, and a particular message order.
