when compared to the operating system and network services.

Middleware offers some unique technological advantages for business and industry. For example, traditional database systems are usually deployed in closed environments where users access the system only via a [[restricted network]] or [[intranet]] (e.g., an enterprise’s internal network). With the phenomenal growth of the [[World Wide Web]], users can access virtually any database for which they have proper access rights from anywhere in the world. Middleware addresses the problem of varying levels of [[interoperability]] among different database structures. Middleware facilitates transparent access to legacy [[database management system]]s (DBMSs) or applications via a [[web server]] without regard to database-specific characteristics.<ref>Peng, C, Chen, S, Chung, J, Roy-Chowdhury, A, and Srinivasan, V.

Intelligent [[Middleware]] (IMW) provides [[real-time intelligence]] and event management through [[intelligent agents]]. The IMW manages the [[real-time processing]] of high volume sensor signals and turns these signals into intelligent and actionable business information. The actionable information is then delivered in end-user power dashboards to individual users or is pushed to systems within or outside the enterprise. It is able to support various heterogeneous types of hardware and software and provides an API for interfacing with external systems. It should have a highly scalable, [[distributed architecture]] which embeds intelligence throughout the network to transform raw data systematically into actionable and relevant knowledge. It can also be packaged with tools to view and manage operations and build advanced network applications most effectively.
