Flow-based Programming
In computer programming, flow-based programming (FBP) is a programming paradigm that defines application software, applications as networks of "black box" process (computer science), processes, which exchange data across predefined connections by message passing, where the connections are specified ''externally'' to the processes. These black box processes can be reconnected endlessly to form different applications without having to be changed internally. FBP is thus naturally Software componentry, component-oriented. FBP is a particular form of dataflow programming based on bounded buffers, information packets with defined lifetimes, named ports, and separate definition of connections. Introduction Flow-based programming defines applications using the metaphor of a "data factory". It views an application not as a single, sequential process, which starts at a point in time, and then does one thing at a time until it is finished, but as a network of asynchronous processes commun ...

Computer Programming
Computer programming is the process of performing a particular computation (or more generally, accomplishing a specific computing result), usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms (usually in a chosen programming language, commonly referred to as coding). The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algori ...

Service-oriented Architecture
In software engineering, service-oriented architecture (SOA) is an architectural style that focuses on discrete services instead of a monolithic design. By consequence, it is also applied in the field of software design where services are provided to the other components by application components, through a communication protocol over a network. A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online. SOA is also intended to be independent of vendors, products and technologies. Service orientation is a way of thinking in terms of services and service-based development and the outcomes of services. A service has four properties according to one of many definitions of SOA: # It logically represents a repeatable business activity with a specified outcome. # It is self-contained. # It is a black box for its consumers, meaning the consumer does not have to be aware of the s ...

Configurable Modularity
Configurable modularity is a term coined by Raoul de Campo of IBM Research and later expanded on by Nate Edwards of the same organization, denoting the ability to reuse independent components by changing their interconnections, but not their internals.N.P. Edwards, ''On the Architectural Requirements of an Engineered System'', IBM Research Report, RC 6688 (#28797), T.J. Watson Research Center, Yorktown Heights, NY, 8/18/1977 In Edwards' view this characterizes all successful reuse systems, and indeed all systems which can be described as "engineered".

Component-based Software Engineering
Component-based software engineering (CBSE), also called component-based development (CBD), is a branch of software engineering that emphasizes the separation of concerns with respect to the wide-ranging functionality available throughout a given software system. It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software. Software engineering practitioners regard components as part of the starting platform for service-orientation. Components play this role, for example, in web services, and more recently, in service-oriented architectures (SOA), whereby a component is converted by the web service into a ''service'' and subsequently inherits further characteristics beyond that of an ordinary component. Components can produce or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Buffer
In computer science, a circular buffer, circular queue, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. This structure lends itself easily to buffering data streams. There were early circular buffer implementations in hardware. Overview A circular buffer first starts out empty and has a set length. In the diagram below is a 7-element buffer: : Assume that 1 is written in the center of a circular buffer (the exact starting location is not important in a circular buffer): : Then assume that two more elements are added to the circular buffer — 2 & 3 — which get put after 1: : If two elements are removed, the two oldest values inside of the circular buffer would be removed. Circular buffers use FIFO (''first in, first out'') logic. In the example, 1 & 2 were the first to enter the circular buffer, they are the first to be removed, leaving 3 inside of the buffer. : If the buffer has 7 ele ...

Technical Disclosure Bulletins
The IBM Technical Disclosure Bulletin was a technical publication produced by IBM between 1958 and 1998. The purpose of the Bulletin was to disclose inventions that IBM did not want their competitors to get patents on. The Bulletin was a form of defensive publication. By publishing the details of how to make and use the invention, patent examiners could have a searchable source of prior art that they could cite against subsequent patent applications filed by others on the same or similar inventions. The Bulletin has been cited over 48,000 times in various United States patents.Delphion Web sitehttp://www.delphion.com/search-prior_art#tdb retrieved on June 20, 2006 See also *United States Statutory Invention Registration In former United States patent law, a statutory invention registration (SIR) was a publication of an invention by the United States Patent and Trademark Office (USPTO).

Coroutines
Coroutines are computer program components that generalize subroutines for non-preemptive multitasking, by allowing execution to be suspended and resumed. Coroutines are well-suited for implementing familiar program components such as cooperative tasks, exceptions, event loops, iterators, infinite lists and pipes. Melvin Conway coined the term ''coroutine'' in 1958 when he applied it to the construction of an assembly program. The first published explanation of the coroutine appeared later, in 1963. Comparison with Subroutines Subroutines are special cases of coroutines. When subroutines are invoked, execution begins at the start, and once a subroutine exits, it is finished; an instance of a subroutine only returns once, and does not hold state between invocations. By contrast, coroutines can exit by calling other coroutines, which may later return to the point where they were invoked in the original coroutine; from the coroutine's point of view, it is not exiting but calling a ...

Melvin Conway
Melvin Edward Conway is an American computer scientist, computer programmer, and hacker who coined what is now known as Conway's law: "Organizations, who design systems, are constrained to produce designs which are copies of the communication structures of these organizations." The adage remains relevant in modern software engineering and is still being referenced and investigated. Apart from the above, Conway is perhaps most famous for developing the concept of coroutines. Conway coined the term ''coroutine'' in 1958 and he was the first to apply the concept to an assembly program. He later authored a seminal paper on the subject of coroutines, titled "Design of a Separable Transition-diagram Compiler", which included the first published explanation of the concept. In this paper, he proposed organizing a compiler as a set of coroutines, which allows using separate passes while debugging and then running a single pass compiler in production. Another famous paper is his 1958 propo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
