Change Impact Analysis
Change impact analysis (IA) or impact analysis is the analysis of changes within a deployed product or application and their potential consequences. Change impact analysis is defined by Bohnner and Arnold as "identifying the potential consequences of a change, or estimating what needs to be modified to accomplish a change", and they focus on IA in terms of scoping changes within the details of a design. In contrast, Pfleeger and Atlee focus on the risks associated with changes and state that IA is: "the evaluation of the many risks associated with the change, including estimates of the effects on resources, effort, and schedule". Both the design details and risks associated with modifications are critical to performing IA within the change management processes. A technical colloquial term is also mentioned sometimes in this context, dependency hell. Types of impact analysis techniques IA techniques can be classified into three types: * Trace * Dependency * Experiential Bohne ...

Static Analysis
Static analysis, static projection, or static scoring is a simplified analysis wherein the effect of an immediate change to a system is calculated without regard to the longer-term response of the system to that change. If the short-term effect is then extrapolated to the long term, such extrapolation is inappropriate. Its opposite, dynamic analysis or dynamic scoring, is an attempt to take into account how the system is likely to respond to the change over time. One common use of these terms is budget policy in the United States, although it also occurs in many other statistical disputes. Examples A famous example of extrapolation of static analysis comes from overpopulation theory. Starting with Thomas Malthus at the end of the 18th century, various commentators have projected some short-term population growth trend for years into the future, resulting in the prediction that there would be disastrous overpopulation within a generation or two. Malthus himself essentially clai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rational DOORS
Rational Dynamic Object Oriented Requirements System (DOORS) (formerly Telelogic DOORS) is a requirement management tool. It is a client–server application, with a Windows-only client and servers for Linux, Windows, and Solaris. There is also a web client, DOORS Web Access. Rational DOORS has its own programming language called DOORS eXtension Language (DXL). Rational DOORS Next Generation is now developed on the IBM Jazz platform. The Jazz platform uses Open Services for Lifecycle Collaboration (OSLC). In order to complete its functionality, Rational DOORS has an open architecture that supports third-party plugins. DOORS was originally published by Quality Systems and Software Ltd (QSS) in 1991. Telelogic acquired QSS in mid-2000 and IBM acquired Telelogic in 2008. History DOORS was created by Dr Richard Stevens, a researcher through the 1970's and 1980's at the European Space Agency's Research Institute (ESRIN). The first version was provided to the UK Ministry of Defe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Search Engine Optimization
Search engine optimization (SEO) is the process of improving the quality and quantity of website traffic to a website or a web page from search engines. SEO targets unpaid traffic (known as "natural" or "organic" results) rather than direct traffic or paid traffic. Unpaid traffic may originate from different kinds of searches, including image search, video search, academic search, news search, and industry-specific vertical search engines. As an Internet marketing strategy, SEO considers how search engines work, the computer-programmed algorithms that dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. SEO is performed because a website will receive more visitors from a search engine when websites rank higher on the search engine results page (SERP). These visitors can then potentially be converted into customers. History Webmast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visual Expert
Visual Expert is a static code analysis tool, extracting design and technical information from software source code by reverse-engineering, used by programmers for software maintenance, modernization or optimization. It is designed to parse several programming languages at the same time (PL/SQL, Transact-SQL, PowerBuilder...) and analyze cross-language dependencies, in addition to each language's source code. Visual Expert checks source code against hundreds of code inspection rules for vulnerability assessment, bug fix, and maintenance issues. Features * Cross-references exploration: Impact Analysis, E/R diagrams, call graphs, CRUD matrix, dependency graphs. * Software documentation: a documentation generator produces technical documentation and low-level design descriptions. *Inspect the code to detect bugs, security vulnerabilities and maintainability issues. Native integration with Jenkins. *Reports on duplicate code, unused objects and methods and naming conventio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JRipples
JRipples is a change impact analysis tool for the Java programming language. It helps a developer calculate the impact of software change. It is an open source Eclipse plug-in. The tool not only give relevant program analysis, but it also organizes the steps of change propagation. When a change is made to software, the change will quite often have an undesirable or unintended impact on the software as a whole. During a change, JRipples can be run to assist the developer in identifying the impact of the change. This tool analyzes a program and marks classes which need attention from the developer. The developer will then visit each marked class and decide if the impact requires refactoring or not. This frees the developer from trivial duties, so they can be more effective. History JRipples was developed by Maksym Petrenko starting 2005. Petrenko was a member of SEVERE group of the Wayne State University Department of Computer Science in Detroit, Michigan. The resea ...

FindBugs
FindBugs is an open-source static code analyser created by Bill Pugh and David Hovemeyer which detects possible bugs in Java programs. Potential errors are classified in four ranks: (i) scariest, (ii) scary, (iii) troubling and (iv) of concern. This is a hint to the developer about their possible impact or severity. FindBugs operates on Java bytecode, rather than source code. The software is distributed as a stand-alone GUI application. There are also plug-ins available for Eclipse, NetBeans, IntelliJ IDEA, Gradle, Hudson, Maven, Bamboo and Jenkins. Additional rule sets can be plugged in FindBugs to increase the set of checks performed.

Integrated Development Environment
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not. The boundary between an IDE and other parts of the broader software development environment is not well-defined; sometimes a version control system or various tools to simplify the construction of a graphical user interface (GUI) are integrated. Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram for use in object-oriented software development. Overview Integrated development environments are designed to maximize programmer productivity by providing tight-knit components with similar user interfaces. IDEs present a single pro ...

Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce s ...

Change Management (engineering)
The change request management process in systems engineering is the process of requesting, determining attainability, planning, implementing, and evaluating of changes to a system. Its main goals are to support the processing and traceability of changes to an interconnected set of factors. Introduction There is considerable overlap and confusion between change request management, change control and configuration management. The definition below does not yet integrate these areas. Change request management has been embraced for its ability to deliver benefits by improving the affected system and thereby satisfying "customer needs," but has also been criticized for its potential to confuse and needlessly complicate change administration. In some cases, notably in the Information Technology domain, more funds and work are put into system maintenance (and change request management) than into the initial creation of a system. Typical investment by organizations during initial implementa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deb (file Format)
deb is the format, as well as extension of the software package format for the Debian Linux distribution and its derivatives. Design Debian packages are standard Unix ar archives that include two tar archives. One archive holds the control information and another contains the installable data. dpkg provides the basic functionality for installing and manipulating Debian packages. Generally end users don't manage packages directly with dpkg but instead use the APT package management software or other APT front-ends such as aptitude ( nCurses) and synaptic ( GTK). Debian packages can be converted into other package formats and vice versa using alien, and created from source code using checkinstall or the Debian Package Maker. Some core Debian packages are available as udebs ("micro debs"), and are typically used only for bootstrapping a Debian installation. Although these files use the ''udeb'' filename extension, they adhere to the same structure specification as ordi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RPM Package Manager
RPM Package Manager (RPM) (originally Red Hat Package Manager, now a recursive acronym) is a free and open-source package management system. The name RPM refers to the file format and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base. Although it was created for use in Red Hat Linux, RPM is now used in many Linux distributions such as PCLinuxOS, Fedora, AlmaLinux, CentOS, openSUSE, OpenMandriva and Oracle Linux. It has also been ported to some other operating systems, such as Novell NetWare (as of version 6.5 SP3), IBM's AIX (as of version 4), IBM i, and ArcaOS. An RPM package can contain an arbitrary set of files. Most RPM files are “binary RPMs” (or BRPMs) containing the compiled version of some software. There are also “source RPMs” (or SRPMs) containing the source code used to build a binary package. These have an appropriate tag in the file head ...
