The problem with the term "ebusiness" is that there seems to be as many definitions as there are software vendors. This course starts with a simple definition, "doing business over the Web." As this definition is refined and expanded, you'll see that ebusiness encompasses a continuum of options, from simple web hosting to ecommerce, internal and external business integration, and web services. The course describes the multiple options that are available and provides examples designed to help you place your organization's ebusiness goals on the spectrum of available options.
As you will see, various ebusiness implementations use a complex array of technologies. To the uninitiated, these technologies seem like an alphabet soup of options, including HTTP, HTML, CGI, URL, JSP, EJB, WAS, XML, XSL, UDDI, WSDL, SOAP, and others. This course introduces these technologies, placing them on the ebusiness continuum according to how they satisfy business requirements.
The purpose of this course is twofold. For IT managers and others interested in ebusiness concepts, it provides an overview of the available technologies. You will see the role of each technology and how they fit together in a typical ebusiness implementation. For IBM i programmers, the course provides the background information needed to understand the remaining courses of this series.
