Software Documentation
Software documentation is written text or illustration that accompanies computer software or is embedded in the source code. The documentation either explains how the software operates or how to use it, and may mean different things to people in different roles. Documentation is an important part of software engineering. Types of documentation include: * Requirements – Statements that identify attributes, capabilities, characteristics, or qualities of a system. This is the foundation for what will be or has been implemented. * Architecture/Design – Overview of software. Includes relations to an environment and construction principles to be used in design of software components. * Technical – Documentation of code, algorithms, interfaces, and APIs. * End user – Manuals for the end-user, system administrators and support staff. * Marketing – How to market the product and analysis of the market demand. Requirements documentation Requirements documentation is the desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Evolution
Software evolution is the continual development of a piece of software after its initial release to address changing stakeholder and/or market requirements. Software evolution is important because organizations invest large amounts of money in their software and are completely dependent on this software. Software evolution helps software adapt to changing businesses requirements, fix defects, and integrate with other changing systems in a software system environment. General introduction Fred Brooks, in his key book ''The Mythical Man-Month'', states that over 90% of the costs of a typical system arise in the maintenance phase, and that any successful piece of software will inevitably be maintained. In fact, Agile methods stem from maintenance-like activities in and around web based technologies, where the bulk of the capability comes from frameworks and standards. Software maintenance addresses bug fixes and minor enhancements, while software evolution focuses on adaptation and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semantic Analysis (compilers)
Semantic analysis or context sensitive analysis is a process in compiler construction, usually after parsing, to gather necessary semantic information from the source code In computing, source code, or simply code, is any collection of code, with or without comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the .... It usually includes type checking, or makes sure a variable is declared before use which is impossible to describe in the extended Backus–Naur form and thus not easily detected during parsing.

Software Visualization
Software visualization or software visualisation refers to the visualization of information of and related to software systems—either the architecture of its source code or metrics of their runtime behavior—and their development process by means of static, interactive or animated 2-D or 3-D visual representations of their structure, execution, behavior, and evolution. Software system information Software visualization uses a variety of information available about software systems. Key information categories include: * implementation artifacts such as source codes, * software metric data from measurements or from reverse engineering, * traces that record execution behavior, * software testing data (e.g., test coverage) * software repository data that tracks changes. Objectives The objectives of software visualization are to support the understanding of software systems (i.e., its structure) and algorithms (e.g., by animating the behavior of sorting algorithms) as well ...

Data Flow Analysis
In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data is commonly used in scientific research, economics, and in virtually every other form of human organizational activity. Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represents the raw facts and figures which can be used in such a manner in order to capture the useful information out of it. D ...

Computer Multitasking
In computing, multitasking is the concurrent execution of multiple tasks (also known as processes) over a certain period of time. New tasks can interrupt already started ones before they finish, instead of waiting for them to end. As a result, a computer executes segments of multiple tasks in an interleaved manner, while the tasks share common processing resources such as central processing units (CPUs) and main memory. Multitasking automatically interrupts the running program, saving its state (partial results, memory contents and computer register contents) and loading the saved state of another program and transferring control to it. This "context switch" may be initiated at fixed time intervals ( pre-emptive multitasking), or the running program may be coded to signal to the supervisory software when it can be interrupted ( cooperative multitasking). Multitasking does not require parallel execution of multiple tasks at exactly the same time; instead, it allows more than o ...

Concurrency Control
In information technology and computer science, especially in the fields of computer programming, operating systems, multiprocessors, and databases, concurrency control ensures that correct results for concurrent operations are generated, while getting those results as quickly as possible. Computer systems, both software and hardware, consist of modules, or components. Each component is designed to operate correctly, i.e., to obey or to meet certain consistency rules. When components that operate concurrently interact by messaging or by sharing accessed data (in memory or storage), a certain component's consistency may be violated by another component. The general area of concurrency control provides rules, methods, design methodologies, and theories to maintain the consistency of components operating concurrently while interacting, and thus the consistency and correctness of the whole system. Introducing concurrency control into a system means applying operation constraints w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Metrics
In software engineering and development, a software metric is a standard of measure of a degree to which a software system or process possesses some property. Even if a metric is not a measurement (metrics are functions, while measurements are the numbers obtained by the application of metrics), often the two terms are used as synonyms. Since quantitative measurements are essential in all sciences, there is a continuous effort by computer science practitioners and theoreticians to bring similar approaches to software development. The goal is obtaining objective, reproducible and quantifiable measurements, which may have numerous valuable applications in schedule and budget planning, cost estimation, quality assurance, testing, software debugging, software performance optimization, and optimal personnel task assignments. Common software measurements Common software measurements include: * ABC Software Metric * Balanced scorecard * Bugs per line of code * Code coverage * Coh ...

Rational Rose
Rational Rose XDE, an "eXtended Development Environment" for software developers, integrates with Microsoft Visual Studio .NET and Rational Application Developer. The Rational Software division of IBM, which previously produced Rational Rose, wrote this software. With the Rational June 2006 Product Release, IBM withdrew the “XDE” family of products and introduced the Rational Rose family of products as replacements. The Rational Rose family of products is a set of UML modeling tools for software design. The Unified Modeling Language (UML) is the industry-standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems. It simplifies the complex process of software design, creating a "blueprint" for construction of software systems. Rational Rose could also use source-based reverse engineering; the combination of this capability with source generation from diagrams was dubbed roundtrip engineering. A 2007 book noted that oth ...

Rigi (software)
__NOTOC__ Rigi is an interactive graph editor tool for software reverse engineering using the white box method, i.e. necessitating source code, thus it is mainly aimed at program comprehension. Rigi is distributed by its main author, Hausi A. Müller and the Rigi research group at the University of Victoria. Rigi provides interactive links from the graphs it produces to the source code, but not vice versa. Rigi renders trees and grid-layout graphs using its own internal engine, but relies on University of Passau's GraphEd for more advanced layouts. The public version of Rigi has built-in parsers ("fact extractors") for C and Cobol, and can leverage the C++ parser of IBM Visual Age. It can also accept external data in an RSF format (it introduced), so external parses can also feed it data, for example SHriMP tool's Java parser. Some efforts were made to integrate Rigi in Microsoft Visual Studio .NET. Early versions of Bauhaus were also built on top of Rigi; the author of this lat ...

Sourcetrail
Sourcetrail was a FOSS source code explorer that provided interactive dependency graphs and support for multiple programming languages including C, C++, Java and Python. History The project was started by Eberhard Gräther after an internship at Google where he worked on Google Chrome, and noticed that he consumed a lot of time (1 month) to implement a simple feature that he expected to be done in 1–2 hours. This was his motivation to develop a tool that helps in understanding the consequences of source code modifications. The project started as a commercial project in 2016 under the name Coati. In November 2019, Sourcetrail was released as open-source software under version three of the GNU General Public License. The project was discontinued in 2021. https://web.archive.org/web/20211115131149/https://www.sourcetrail.com/blog/discontinue_sourcetrail/ Blog post on discontinuing Sourcetrail.
