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.

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. 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 Extension, extend or extended may refer to: Mathematics Logic or set theory * Axiom of extensionality * Extensible cardinal * Extension (model theory) * Extension (proof theory) * Extension (predicate logic), the set of tuples of values ... and thus not easily detected during parsing.

Software Visualization
Software consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or interpreter to execute on the architecture's hardware. Over time, software has become complex, owing to developments in networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applications # application software, which performs specific tasks for users The rise of clou ...

Data Flow Analysis
Data-flow analysis is a technique for gathering information about the possible set of values calculated at various points in a computer program. It forms the foundation for a wide variety of compiler optimizations and program verification techniques. A program's control-flow graph (CFG) is used to determine those parts of a program to which a particular value assigned to a variable might propagate. The information gathered is often used by compilers when optimizing a program. A canonical example of a data-flow analysis is reaching definitions. Other commonly used data-flow analyses include live variable analysis, available expressions, constant propagation, and very busy expressions, each serving a distinct purpose in compiler optimization passes. A simple way to perform data-flow analysis of programs is to set up data-flow equations for each node of the control-flow graph and solve them by repeatedly calculating the output from the input locally at each node until the whole ...

Computer Multitasking
In computing, multitasking is the concurrent computing, concurrent execution of multiple tasks (also known as Process (computing), 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 computing, parallel execution of multiple task ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Metrics
In software engineering and Software development, 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 research, 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 Program optimization, performance optimization, and optimal personnel task assignments. Common software measurements Common software measurements include: * ABC Software Metric * Bal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rational Rose
Rational Rose was a development environment for Unified Modeling Language. It integrates with Microsoft Visual Studio .NET and Rational Application Developer. The Rational Software division of IBM, which previously produced Rational Rose, wrote this software. The Rational Rose family of products is a set of UML modeling tools for software design. Rational Rose could also use source-based reverse engineering; the combination of this capability with source generation from diagrams was dubbed roundtrip engineering. However, other UML tools are also capable of this, including Borland Together, ESS-Model, BlueJ, and Fujaba. The Rational Rose family allows integration with legacy integrated development environments or languages. For more modern architectures, Rational Software Architect and Rational Software Modeler were developed. These products were created matching and surpassing Rose XDE capabilities to include support for UML 2.x, pattern customization support, the late ...

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 l ...

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.
