Systems integration is the core to providing a high-level set of features that provide functionality for business-to-business e-commerce and web based systems. These high-level feature sets are made up of a group of sub systems which each play their part to providing functionality to the one main system. This process of information technology integration gives a business the ability to provide more services and functionality to its clients. These systems are achieved through the use of these three service descriptions parts:
- Schema definition
- Interface definition
- Location definition
Web services are "a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically Web Services Description Language WSDL). Other systems interact with the web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other web-related standards." As defined by W3C.
I have had no experience with online systems in my previous studies. As a network engineer student this subject has broadened my knowledge into this side of computing. While I find online systems very useful in a lot of day to day activities, while doing online banking and purchasing of goods, I think I might leave the creation of online systems to somebody with a bit more experience...well for the time being anyway, while I hone my skill set in this field. I have found this subject to be a quite worth while and have learnt so much about online systems, an area of IT that I had very limited knowledge.
