Computer Middleware

This is an excerpt from the paper...

Middleware is defined as “software that connects two otherwise separate applications” (Webopedia 1). Middleware represents a variety of products that link two applications, such as a company database to a Web server. Sometimes known as plumbing, middleware products are not part of any application but they serve as the gap or bridge between two others. The following review of literature will focus on middleware, and the growing need for it among consumers, businesses, government, and academic institutions. After a discussion of middleware in general, the literature review will focus on the following most common categories of middleware: TP Monitors, Database Access Systems, RPC Systems, DCE Environments, and Object Request Brokers.

The growing reliance on the Internet and Web technologies comes in many models: business-to-consumer, business-to-business, and business-to-intermediary-to-consumer. So, too, businesses are relying more and more on the Intranet, an internal Internet that allows authorized employees to access the company database via the Internet. In addition to this, the Semantic Web is being developed which instead of acting as the Internet and HTML language for human-to-human interactions, the Semantic Web uses XML language for machine-to-machine interactions. In light of these developments, there is a greater need for middleware, or so

rers. One such company is Hewlett-Packard which “Recently closed a glaring gap in its software product portfolio with the delivery of its HP Netaction middleware suite. The suite should give users a wide range of XML-based application and service integration capabilities that are needed for building e-commerce business-to-business environments” (Vijayan 20). Middleware does have the drawback of a fairly rapid shelf-life. This is especially true when it comes to mobile or wireless networks. Wireless middleware is one of the preferred ways of linking e-business applications to the wireless Web because it does not rewrite the applications to fit with mobile devices. Instead, it imports existing ASP, HTML, JSP and other types of files into one system by adding XML tags. These tags dictate the components of a Web page specifically for each kind of device. Still, as one IT expert warns “Be careful the [middleware] software may become obsolete before you have finished implementing it. That is especially true of middleware designed specifically for wireless networks” (Evans PG23). The analysis will now give a brief review of literature associated with the following most common forms of middleware: TP Monitors, Database Access
