support for specific functions of e‐business |
|
Internet protocol suite = |
- Application layer, - Transport Layer, - Internet layer, - Link layer. |
|
URL structure consists of: |
- Protocol indicator, - domain adress, - document adress. |
|
The internet and the web are not the same thing: What is the difference:? |
the web is a hypertext based informationstructure using the internet as underlyingcommunication technology – one cannot ‘surf theinternet |
|
Protocols and languages (for internet or web) aredifferent things: What is the difference? |
- Protocols are used to specifyhow communication takes place, - Languages tospecify what is communicated ‐ protocols areabout transport, languages about content. |
|
Advanced platform technology provides:? |
A general‐purpose infrastructure for e‐business |
|
Specific e‐business standardization platforms are:? |
- ebXML, - Rosettanet |
|
General e‐business technology platforms: |
- Web Services technology, - Multi‐agent technology. |
|
Hybrid platforms: = |
combining several platforms. |
|
The ebXML standard provides: ? |
A high‐leveltechnological framework for theimplementation of software that supports e‐business processes over the Internet. |
|
The ebXML development was initiated in 1999by who? |
The standardization organization OASIS andthe United Nations/ECE agency CEFACT. |
|
|
This is a web service |
|
ebXML overview:? |
|
|
Web Service standards:? |
- Languages - Protocols - Software specs |
|
Voor Koen! Mention three languages: |
- XML (voor de SLA) - WSDL - BPEL |
|
(makkelijke vraag) Mention some important protocols: |
HTTP SOAP (mijn favoriet) = Simple Object Access Protocol |
|
Mentions one software spec: |
UDDI |
|
What is a Web service? |
- UDDI group, - W3C |
|
UDDI group = |
Self‐contained, modularbusiness applications that have open, Internetoriented, standards‐based interfaces” |
|
W3C = |
“A software application identified by aURI, whose interfaces and bindings arecapable of being defined, described, anddiscovered as XML artifacts. A web servicesupports direct interactions with othersoftware agents using XML‐based messagesexchanged via Internet‐based protocols. |
|
The Web Services frame work specifies: ? |
an Internet‐based set of technology standards |
|
The basic concept is a Web Service? |
An encapsulatedpiece of software functionality that can be invokedthrough a well‐defined Web interface. |
|
SOC = |
Service-oriented Computing |
|
SOA |
Service-Oriented Architecture. (Later meer hierover) |
|
What is the role of UDDI? |
Given a description of what the service is supposed to do (contract), adynamic search is done for candidate services that are capable of fulfillingthat contract. |
|
|
UDDI visual |
|
What is in UDDI? (deze raad je nooit) |
- White pages: organization, contract info,service - Yellow pages: Classifications of companies and web service using standardized or user-defined taxonomies - Green pages: How to invoke services |
|
What is a Service‐oriented architecture? |
Using the SOC paradigm as a basis for thearchitectural design of information systems, weget service‐oriented architecture (SOA). |
|
SOA applied to enterprise e‐business applicationstypically relies on two main technologies: |
- Managed service platform technology - Enterprise service bus (ESB) |
|
Managed service platform technology = |
provides a setof basic mechanisms for the deployment andmanagement of software services |
|
Enterprise service bus (ESB) technology = |
Implementsthe functionality to easily make interconnectionsbetween services. |
|
Aspect‐oriented technology provides? |
functionality across e‐business functions |
|
Important aspect‐oriented technology classes? |
- Data management technology, - Process management technology, - Human communication technology, - Security technology, - Performance technology, - Mobility technology |
|
What type of architecture system is this? |
Client/server database |
|
What is this? |
Security Technology |
|
Secure Message Exchange and Cryptography = |
- Confidentiality: - Integrity: - Authentication: - Non‐repudiation: |
|
Confidentially = |
massage only readable by sender and the internet receiver.
|
|
Integrity = |
message cannot be changed |
|
Authentication = |
Identity of the sender is assured |
|
Non‐repudiation = |
Sending of receivedmessage is ‘undeniable’ by sender |
|
What type of inscription is this? |
Asymmetric (receiver) |
|
What type of inscription? |
symmetric |
|
What type of inscription? |
Asymmetric (Sender) |
|
Function‐oriented technology supports? |
onespecific e‐business function |
|
Important function‐oriented technology classes are? |

|
Parties in electronic certification? |
|
|
Mapping A to T and T to B elements |
Oke |
|
Internet and Web technologies are ‘default and: |
notexplicit in mappings between A and T aspects |
|
Advanced platform technologies typically underlie acomplete architecture, not visible in A but? |
can influence the choice of A modules |
|
Aspect‐oriented technologies (mapping) |
are used in variousmodules of an e‐business system; may in some casesbe located in dedicated low‐level A modules |
|
Function‐oriented technologies (Mapping) |
can be related toindividual modules identified in the architecture inthe A aspect |
