2 . I ntroduction to the course ( 2 )

Objectives: This course covers several key

technologies that support network-centric computing: Django, XML, SOAP, and Web

• Services. The primary objectives of the

course are:

• to learn programming paradigms used in

current network centric computing and some

• f the key technologies used to implement

that paradigm.

• to introduce current research and

development activities in World Wide Web.

2 . I ntroduction to the course ( 3 )

• Basic Java Network programming with sockets

and HTTP

• Python
• Django
• XML
• Programing in XML with JAXP, SAX, and DOM

2 . I ntroduction to the course ( 4 )

Workload

• 2 Assignments (20%)
• 1 course project (50%)

4 Project Benchmarks

• 1 midterms (30%)
• 2 Pass/Fail presentations

3 . Basic concepts: ( 1 ) Netw ork- Centric Com puting

Definition? pick one – there are several. It can be lots of different things to

different people.

One common tread is that they all involve

• multiple computers
• working on a common problem
• sharing no common resource other than the

network

3 . Basic concepts ( 2 ) : Protocols

Basically, a protocol is an agreement between the communicating peers on how communication is to proceed.

3 . Basic concepts ( 3 ) : The layering Principle ( 1 )

3 . Basic concepts ( 4 ) : The layering Principle ( 2 )

4 . Service-Oriented Architectures ( 1 )

In SOA all software components are

modeled as services

Web services are one way to implement a

Service-oriented architecture (SOA).

SOA always consist of 3 roles

• Service provider
• Service requestor
• Service registry

4 . Service-Oriented Architectures ( 2 )
