History
Aspect-Oriented Software Development describes a number of approaches to software modularization and composition including, in order of publication, reflection and metaobject protocols, Composition Filters, developed at the University of Twente in the Netherlands, Subject-Oriented Programming (later extended as Multidimensional Separation of Concerns) at IBM, Feature Oriented Programming at University of Texas at Austin, Adaptive Programming at Northeastern University, USA, and Aspect-Oriented Programming (AOP) at Palo Alto Research Center. The term aspect-oriented was introduced by Gregor Kiczales and his team at Palo Alto Research Center who also first developed the explicit concept of AOP and the AOP language called AspectJ which has gained considerable acceptance and popularity within the Java developer community.
Currently, several aspect-oriented programming languages are available for a variety of languages and platforms.
Just as object-oriented programming led to the development of a large class of object-oriented development methodologies, AOP has encouraged a nascent set of software engineering technologies, including methodologies for dealing with aspects, modeling techniques (often based on the ideas of the Unified Modeling Language, UML), and testing technology for assessing the effectiveness of aspect approaches. AOSD now refers to a wide range of software development techniques that support the modularization of crosscutting concerns in a software system, from requirement engineering to analysis and design, architecture, programming and implementation techniques, testing and software maintenance techniques.
Aspect-oriented software development has constantly gained in popularity, and is the subject of an annual conference, the International Conference on Aspect-Oriented Software Development, held for the first time in 2002 in Enschede, The Netherlands. AOSD is a rapidly evolving area. It is a popular topic of Software Engineering research, especially in Europe, where research activities on AOSD are coordinated by the European Network of Excellence on Aspect-Oriented Software Development (AOSD-Europe), funded by the European Commission.

Famous quotes containing the word history:
“You that would judge me do not judge alone
This book or that, come to this hallowed place
Where my friends’ portraits hang and look thereon;
Ireland’s history in their lineaments trace;
Think where man’s glory most begins and ends
And say my glory was I had such friends.”
—William Butler Yeats (1865–1939)
“America is the only nation in history which miraculously has gone directly from barbarism to degeneration without the usual interval of civilization.”
—Georges Clemenceau (1841–1929)
“Jesus Christ belonged to the true race of the prophets. He saw with an open eye the mystery of the soul. Drawn by its severe harmony, ravished with its beauty, he lived in it, and had his being there. Alone in all history he estimated the greatness of man.”
—Ralph Waldo Emerson (1803–1882)
