In 1972, David Parnas introduced the idea of information hiding. In that paper, he suggests splitting programs into different modules, and listing down and hiding within a module the‘design decisions most likely to change’, so that you need to change just one module when one of those decisions change. Dr. Parnas is also a heavy promoter of ethics in the field of software engineering. The key idea is to design software modules around a single design decision that may change Hoffman, Daniel M.; Weiss David M. David Lorge Parnas (born February 10, 1941) is a Canadian early pioneer of software engineering, who developed the concept of information hiding in modular programming, which is an important element of object-oriented programming today. Wolf's 1985 Ph.D. dissertation developed language features for expressing a module's import/export specifications and the notion of multiple interfaces for a type, both of which are now common in modern computer programming languages. He is a (retired) distinguished career scientist and faculty member at Carnegie Mellon University and Professor Emeritus at LSU. Parnas earned his Ph.D. at Carnegie Mellon University in electrical engineering. Sir Charles Antony Richard Hoare is a British computer scientist. In a concept that may seem obvious now I was thinking about Information Hiding today. According to this idea, lack of information hiding can lead to tightly coupled systems that are hard to maintain. 03 - Parnas CSC407 7 Criteria for decomposition • Modularization 1 – Each major step in the processing was a module • Modularization 2 – Information hiding • Each module has one or more "secrets” • Each module is characterized by its knowledge of design decisions which it hides from all others. Brooks has received many awards, including the National Medal of Technology in 1985 and the Turing Award in 1999. However, in Parnas's seminal 1972 paper On the Criteria to Be Used in Decomposing Systems into Modules, this dictum is expressed in terms of information hiding, and the terms cohesion and coupling are not used.[1].

Parnas is the author of more than 265 papers and reports. Martonosi is noted for her research in computer architecture and mobile computing with a particular focus on power-efficiency. This classic paper by Parnas is the rst publication of the design concept known as information hiding. His published works include highly influential research on the social web, recommendation systems, and collaborative systems. Information hiding is all about hiding design and implementation decisions. Dr Parnas took a public stand against the US Strategic Defense Initiative (also known as "Star Wars") in the mid 1980s, arguing that it would be impossible to write an application of sufficient quality that it could be trusted to prevent a nuclear attack. He points out in that article that use of information about other modules can "disastrously increase the connectivity of the system structure." Born in London, England, he was Dean of the Faculty of Mathematics and Computer Science at the institute for seven years. William Arthur Stewart Buxton is a Canadian computer scientist and designer.

He is also noted for his advocacy of precise documentation. He is also noted for his advocacy of precise documentation. ; Noted for his advocacy of precise documentation. The purpose of information hiding is to obtain a modularization of the code of a system that isolates changes into single modules. The primary argument of Parnas’ paper, besides for modularization of systems, is that we must implement a concept called “Information Hiding” and the explanation of what that means. [5] D. L.

Murphy is a professor in the Department of Computer Science and Associate Dean in the Faculty of Science at the University of British Columbia. His research centers on the theory of cryptography and information security. On his November 2007 paper Stop the Numbers Game, he elaborates on several reasons on why the current number-based academic evaluation system used in many fields by universities all over the world (be it either oriented to the amount of publications or the amount of quotations each of those get) is flawed and, instead of generating more advance of the sciences, it leads to knowledge stagnation. Dr. Parnas is also a heavy promoter of ethics in the field of software engineering. He is also noted for his advocacy of precise documentation. He also taught at the University of North Carolina at Chapel Hill (U.S.), the Technische Hochschule Darmstadt (Germany), the University of Victoria (British Columbia, Canada), McMaster University in Hamilton, Ontario, and University of Limerick (Limerick, Republic of Ireland).
