Software Configuration Management
Software configuration management (SCM), a.k.a. software change and configuration management (SCCM), is the software engineering practice of tracking and controlling changes to a software system; part of the larger cross-disciplinary field of configuration management (CM). SCM includes version control and the establishment of baselines. Goals The goals of SCM include: * Configuration identification - Identifying configurations, configuration items and baselines. * Configuration control - Implementing a controlled change process. This is usually achieved by setting up a change control board whose primary function is to approve or reject all change requests that are sent against any baseline. * Configuration status accounting - Recording and reporting all the necessary information on the status of the development process. * Configuration auditing - Ensuring that configurations contain all their intended parts and are sound with respect to their specifying documents, inclu ...

Software Engineering
Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining Application software, software applications. It involves applying engineering design process, engineering principles and computer programming expertise to develop software systems that meet user needs. The terms ''programmer'' and ''coder'' overlap ''software engineer'', but they imply only the construction aspect of a typical software engineer workload. A software engineer applies a software development process, which involves defining, Implementation, implementing, Software testing, testing, Project management, managing, and Software maintenance, maintaining software systems, as well as developing the software development process itself. History Beginning in the 1960s, software engineering was recognized as a separate field of engineering. The development of software engineering was seen as a struggle. Problems included software that was over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software System
A software system is a system of intercommunicating software component, components based on software forming part of a computer system (a combination of Computer hardware, hardware and software). It "consists of a number of separate Computer program, programs, configuration files, which are used to set up these programs, system documentation, which describes the structure of the system, and user documentation, which explains how to use the system". A software system differs from a computer program or software. While a computer program is generally a set of instructions (source code, source, or object code) that perform a specific task, a software system is more or an encompassing concept with many more components such as specification, Software test automation, test results, end-user documentation, maintenance records, etc.' The use of the term software system is at times related to the application of systems theory approaches in the context of software engineering. A software sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Configuration Management
Configuration management (CM) is a management process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings. Introduction CM applied over the life cycle of a system provides visibility and control of its performance, functional, and physical attributes. CM verifies that a system performs as intended, and is identified and documented in sufficient detail to support its projected life cycle. The CM proces ...

Version Control
Version control (also known as revision control, source control, and source code management) is the software engineering practice of controlling, organizing, and tracking different versions in history of computer files; primarily source code text files, but generally any type of file. Version control is a component of software configuration management. A ''version control system'' is a software tool that automates version control. Alternatively, version control is embedded as a feature of some systems such as word processors, spreadsheets, collaborative groupware, web docs, and content management systems, e.g., Help:Page history, Wikipedia's page history. Version control includes viewing old versions and enables Reversion (software development), reverting a file to a previous version. Overview As teams develop software, it is common to Software deployment, deploy multiple versions of the same software, and for different developers to work on one or more different versions ...

Baseline (configuration Management)
In configuration management, a baseline is an agreed description of the attributes of a product, at a point in time, which serves as a basis for defining change. A change is a movement from this baseline state to a next state. The identification of significant changes from the baseline state is the central purpose of baseline identification.CMMI Product Team, "Chpt 7, Maturity Level 2: Managed, Configuration Management, SP 1.3," in ''Capability Maturity Model Integration, Version 1.1 (CMMI-SE/SW/IPPD/SS, V1.1): Staged Representation,'' Carnegie Mellon Software Engineering Institute. Typically, significant states are those that receive a formal approval status, either explicitly or implicitly. An approval status may be attributed to individual items, when a prior definition for that status has been established by project leaders, or signified by mere association to a particular established baseline. Nevertheless, this approval status is usually recognized publicly. A baseline may b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Configuration Item
The term configuration item (CI) refers to the fundamental structural unit of a configuration management system. Examples of CIs include individual hardware or software components. The configuration-management system oversees the life of the CIs through a combination of processes and tools by implementing and enabling the fundamental elements of identification, change management, status accounting, and audits. This system aims to avoid the introduction of errors related to lack of testing as well as of incompatibilities with other CIs. Description The term "configuration item" can be applied to a product, allocated component of a product, or both that satisfies an end use function, has distinct requirements, functionality and/or product relationships, and is designated for distinct control in the configuration-management system. Configuration items and their associated product configuration information versions, and approved changes, form the basis of any current approved configu ...

Change Control
Within quality management systems (QMS) and information technology (IT) systems, change control is a process—either formal or informal—used to ensure that changes to a product or system are introduced in a controlled and coordinated manner. It reduces the possibility that unnecessary changes will be introduced to a system without forethought, introducing faults into the system or undoing changes made by other users of software. The goals of a change control procedure usually include minimal disruption to services, reduction in back-out activities, and cost-effective utilization of resources involved in implementing change. According to the Project Management Institute, change control is a "process whereby modifications to documents, deliverables, or baselines associated with the project are identified, documented, approved, or rejected." Change control is used in various industries, including in IT, software development, the pharmaceutical industry, the medical device industr ...

Change Control Board
In software development, projects and programs, a change control board (CCB) is a committee that consists of Subject Matter Experts (''SME'', e.g. software engineers, testing experts, etc.) and Managers (e.g. Quality Assurance managers), who decide whether to implement proposed changes to a project. The main objective of a CCB is to ensure the client accepts the project. Factors affecting a CCB's decision can include the project's phase of development, budget, schedule, and quality goals. Change control (see Scope management) is also part of Requirements engineering. CCBs are most associated with the waterfall method of software development, but can be seen as having analogues in some implementations of Agile software development. The Change Control Board will review any proposed changes from the original baseline requirements that were agreed upon with the client. If any change is agreed upon by the committee, the change is communicated to the project team and the client, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Build Management
A software build is the process of converting source code files into standalone software artifact(s) that can be run on a computer, or the result of doing so. In software production, builds optimize software for performance and distribution, packaging into formats such as '.''exe'; '.deb'; '.apk. The build process often employs specialized tools such as CMake, Make, or Gradle, and integrates with automation systems including Jenkins or Git Actions. Despite advancements, challenges such as dependency conflicts, platform compatibility, and long compile times, remain problems. Software development In software development, building software is an end-to-end process that involves many distinct functions. Some of these functions are described below. Version control The version control function carries out activities such as workspace creation and updating, baselining and reporting. It creates an environment for the build process to run in and captures metadata about the inputs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Process Management (computing)
A process is a program in execution, and an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes. To meet these requirements, The OS must maintain a data structure for each process, which describes the state and resource ownership of that process, and which enables the operating system to exert control over each process. Multiprogramming In any modern operating system, there can be more than one instance of a program loaded in memory at the same time. For example, more than one user can be executing the same program, with each user having separate copies of the program loaded into memory. With some programs, it is possible to have one copy loaded into memory, while several users have shared access to it so that they can each execute the same program-code. Such a program is called ...

Teamwork
Teamwork is the collaborative effort of a group to achieve a common goal or to complete a task in an effective and efficient way. Teamwork is seen within the framework of a team, which is a group of interdependent individuals who work together towards a common goal. The four key characteristics of a team include a shared goal, interdependence, boundedness, stability, the ability to manage their own work and internal process, and operate in a bigger social system. Teams need to be able to leverage resources to be productive (i.e. playing fields or meeting spaces, scheduled times for planning, guidance from coaches or supervisors, support from the organization, etc.), and clearly defined roles within the team in order for everyone to have a clear purpose. Teamwork is present in contexts including an industrial organization (formal work teams), athletics (sports teams), a school (classmates working on a project), and the healthcare system (operating room teams). In each of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Computing
Cloud computing is "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand," according to International Organization for Standardization, ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Pooling (resource management), Resource pooling: " The provider' ...
