The widely recognized value of icons, diagrams, and other graphical notations in human–computer interaction and human–human (interhuman) communication, and the decreasing cost of hardware technologies and graphics software have caused the development of a novel approach termed visual programming or graphical programming . Visual programming covers a wide variety of activities that make extensive use of icons and diagrams to convey information and to allow for multimodal communication and interaction between humans and computers. Indeed, in spite of the terminology adopted, “visual programming” does not denote merely the specification of visual programs but rather refers to the ability of using graphics as a communication means in any activity that involves human–computer interaction. Typical activities that benefit from the use of visual languages are generation of graphical user interfaces, database manipulation, supporting novice users in program comprehension, and program composition. Thus, a huge amount of visual programming languages have been introduced. Such languages allow a user to communicate with the system by spatially arranging visual objects on the screen, so as to compose a “visual sentence.” It is worth pointing out that despite their names, Visual Microsoft languages are not actually visual programming languages. Indeed, they are textual programming languages enhanced with a graphical user interface builder meant to support the programmer in the construction of the user interface portion of the program. These languages and there formal specifications are discussed. Also discussed is the implementation of systems that generate these measurements.

With the emergence of distributed resources and grid technologies there is a need to provide higher level informatics infrastructures allowing scientists to easily create and execute meaningful data integration and analysis processes that take advantage of the distributed nature of the available resources. These resources typically include heterogeneous data sources, computational resources for task execution and various application-specific services. The effort of the high performance community has so far mainly focused on the delivery of low-level informatics infrastructures enabling the basic needs of grid applications. Such infrastructures are essential but do not directly help end-users in creating generic and re-usable applications. In this paper, we present the Discovery Net architecture for building grid-based knowledge discovery applications. Our architecture enables the creation of high-level, re-usable and distributed application workflows that use a variety of common types of distributed resources. It is built on top of standard protocols and standard infrastructures such as Globus but also defines its own protocols such as the Discovery Process Mark-up Language for data flow management. We discuss an implementation of our architecture and evaluate it by building a real-time genome annotation environment on top.
