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 communica ...

Computer Programming
Computer programming or coding is the composition of sequences of instructions, called computer program, programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing source code, code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit. Proficient programming usually requires expertise in several different subjects, including knowledge of the Domain (software engineering), application domain, details of programming languages and generic code library (computing), libraries, specialized algorithms, and Logic#Formal logic, formal logic. Auxiliary tasks accompanying and related to programming include Requirements analysis, analyzing requirements, Software testing, testing, debugging (investigating and fixing problems), imple ...

Service-oriented Architecture
In software engineering, service-oriented architecture (SOA) is an architectural style that focuses on discrete services instead of a monolithic design. SOA is a good choice for system integration. 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 ...

Lazy Evaluation
In programming language theory, lazy evaluation, or call-by-need, is an evaluation strategy which delays the evaluation of an Expression (computer science), expression until its value is needed (non-strict evaluation) and which avoids repeated evaluations (by the use of Sharing (computer science), sharing). The benefits of lazy evaluation include: * The ability to define control flow (structures) as abstractions instead of Language primitive, primitives. * The ability to define actual infinity, potentially infinite data structures. This allows for more straightforward implementation of some algorithms. * The ability to define partly-defined data structures where some elements are errors. This allows for rapid prototyping. Lazy evaluation is often combined with memoization, as described in Jon Bentley (computer scientist), Jon Bentley's ''Writing Efficient Programs''. After a function's value is computed for that Parameter (computer programming), parameter or set of parameters, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 style of software engineering that aims to construct a software system from software component, components that are loosely-Coupling (computer programming), coupled and Reusability, reusable. This emphasizes the separation of concerns among components. To find the right level of component granularity, software architects have to continuously iterate their component designs with developers. Architects need to take into account user requirements, responsibilities and architectural characteristics. Considerations For large-scale systems developed by large teams, a disciplined culture and process is required to achieve the benefits of CBSE. Third-party software component, Third-party components are often utilized in large systems. The system can be designed visually with the Unified Modeling Language (UML). Each software component, component is shown as a rectangle, and an interface is ... [...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 e ...

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 allow execution to be suspended and resumed, generalizing subroutines for cooperative multitasking. Coroutines are well-suited for implementing familiar program components such as cooperative tasks, exceptions, event loops, iterators, infinite lists and pipes. They have been described as "functions whose execution you can pause". 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. Definition and types There is no single precise definition of coroutine. In 1980 Christopher D. Marlin summarized two widely-acknowledged fundamental characteristics of a coroutine: # the values of data local to a coroutine persist between successive calls; # the execution of a coroutine is suspended as control leaves it, only to carry on where it left off when control re-enters the coroutine at some later stage ...
