Implementation (computer Science)
Implementation is the realization of an application, or execution of a plan, idea, model, design, specification, standard, algorithm, or policy. Industry-specific definitions Computer science In computer science, an implementation is a realization of a technical specification or algorithm as a program, software component, or other computer system through computer programming and deployment. Many implementations may exist for a given specification or standard. For example, web browsers contain implementations of World Wide Web Consortium-recommended specifications, and software development tools contain implementations of programming languages. A special case occurs in object-oriented programming, when a concrete class implements an interface; in this case the concrete class is an ''implementation'' of the interface and it includes methods which are ''implementations'' of those methods specified by the interface.

Plan
A plan is typically any diagram or list of steps with details of timing and resources, used to achieve an objective to do something. It is commonly understood as a temporal set of intended actions through which one expects to achieve a goal. For spatial or planar topologic or topographic sets see map. Plans can be formal or informal: * Structured and formal plans, used by multiple people, are more likely to occur in projects, diplomacy, careers, economic development, military campaigns, combat, sports, games, or in the conduct of other business. In most cases, the absence of a well-laid plan can have adverse effects: for example, a non-robust project plan can cost the organization time and money. * Informal or ad hoc plans are created by individuals in all of their pursuits. The most popular ways to describe plans are by their breadth, time frame, and specificity; however, these planning classifications are not independent of one another. For instance, there is ...

Object-oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of " objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as '' methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with ...

Direct Changeover
Big bang adoption or direct changeover is when a new system is adopted instantly, with no transition period between the old and new systems.Eason, 1988 When a new system needs to be implemented in an organization, there are three different ways to adopt this new system: the big bang adoption, phased adoption and parallel adoption. In case of parallel adoption the old and the new system are running parallel, so all the users can get used to the new system, and meanwhile do their work using the old system. Phased adoption means that the adoption will happen in several phases, so after each phase the system is a little nearer to be fully adopted. With the big bang adoption, the switch between using the old system and using the new system happens at one single date, the so-called instant changeover of the system. Everybody starts to use the new system at the same date and the old system will not be used anymore from that moment on. The advantage of a big bang adoption is that the n ...

Bureaucracy
The term bureaucracy () refers to a body of non-elected governing officials as well as to an administrative policy-making group. Historically, a bureaucracy was a government administration managed by departments staffed with non-elected officials. Today, bureaucracy is the administrative system governing any large institution, whether publicly owned or privately owned. The public administration in many jurisdictions and sub-jurisdictions exemplifies bureaucracy, but so does any centralized hierarchical structure of an institution, e.g. hospitals, academic entities, business firms, professional societies, social clubs, etc. There are two key dilemmas in bureaucracy. The first dilemma revolves around whether bureaucrats should be autonomous or directly accountable to their political masters. The second dilemma revolves around bureaucrats' behavior strictly following the law or whether they have leeway to determine appropriate solutions for varied circumstances. Various commen ...

Public Servants
The civil service is a collective term for a sector of government composed mainly of career civil servants hired on professional merit rather than appointed or elected, whose institutional tenure typically survives transitions of political leadership. A civil servant, also known as a public servant, is a person employed in the public sector by a government department or agency for public sector undertakings. Civil servants work for central and state governments, and answer to the government, not a political party. The extent of civil servants of a state as part of the "civil service" varies from country to country. In the United Kingdom (UK), for instance, only Crown (national government) employees are referred to as "civil servants" whereas employees of local authorities (counties, cities and similar administrations) are generally referred to as "local government civil service officers", who are considered public servants but not civil servants. Thus, in the UK, a civil servant is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legislatures
A legislature is an assembly with the authority to make laws for a political entity such as a country or city. They are often contrasted with the executive and judicial powers of government. Laws enacted by legislatures are usually known as primary legislation. In addition, legislatures may observe and steer governing actions, with authority to amend the budget involved. The members of a legislature are called legislators. In a democracy, legislators are most commonly popularly elected, although indirect election and appointment by the executive are also used, particularly for bicameral legislatures featuring an upper chamber. Terminology The name used to refer to a legislative body varies by country. Common names include: * Assembly (from ''to assemble'') * Congress (from ''to congregate'') * Council (from Latin 'meeting') * Diet (from old German 'people') * Estates or States (from old French 'condition' or 'status') * Parliament (from French ''parler'' 'to speak') By ...

Public Policy
Public policy is an institutionalized proposal or a decided set of elements like laws, regulations, guidelines, and actions to solve or address relevant and real-world problems, guided by a conception and often implemented by programs. Public policy can be considered to be the sum of government direct and indirect activities and has been conceptualized in a variety of ways. They are created and/or enacted on behalf of the public typically by a government. Sometimes they are made by nonprofit organisations or are made in co-production with communities or citizens, which can include potential experts, scientists, engineers and stakeholders or scientific data, or sometimes use some of their results. They are typically made by policy-makers affiliated with (in democratic polities) currently elected politicians. Therefore, the "policy process is a complex political process in which there are many actors: elected politicians, political party leaders, pressure groups, civil serva ...

Political Science
Political science is the scientific study of politics. It is a social science dealing with systems of governance and power, and the analysis of political activities, political thought, political behavior, and associated constitutions and laws. Modern political science can generally be divided into the three subdisciplines of comparative politics, international relations, and Political philosophy, political theory. Other notable subdisciplines are Public administration, public policy and administration, Domestic politics, domestic politics and government, political economy, and political methodology. Furthermore, political science is related to, and draws upon, the fields of economics, Legal education, law, sociology, history, philosophy, human geography, political anthropology, and psychology. Political science is methodologically diverse and appropriates many methods originating in psychology, social research, and political philosophy. Approaches include positivism, Vers ...

Solutions Architect
Solution architecture, term used in information technology with various definitions such as; "A description of a discrete and focused business operation or activity and how IS/ IT supports that operation". Definitions The Open Group's definition of Solution Architecture, as provided above, is accompanied by the following three from Scaled Agile, Gartner and Greefhorst/Proper. It is worth noting that the Open Group does not recognize the role "Solution Architect" in its TOGAF skills framework whilst Glassdoor advertised 55,000 Solution Architect roles in August 2020. * Scaled agile (2020) ''Solution Architect/Engineering is responsible for defining and communicating a shared technical and architectural vision across a "Solution Train" to help ensure the system or Solution under development is fit for its intended purpose.'' * Gartner (2013) ''A solution architecture (SA) is an architectural description of a specific solution.

Technical Analysis
In finance, technical analysis is an analysis methodology for analysing and forecasting the direction of prices through the study of past market data, primarily price and volume. Behavioral economics and quantitative analysis use many of the same tools of technical analysis, which, being an aspect of active management, stands in contradiction to much of modern portfolio theory. The efficacy of both technical and fundamental analysis is disputed by the efficient-market hypothesis, which states that stock market prices are essentially unpredictable, and research on whether technical analysis offers any benefit has produced mixed results. History The principles of technical analysis are derived from hundreds of years of financial market data. Some aspects of technical analysis began to appear in Amsterdam-based merchant Joseph de la Vega's accounts of the Dutch financial markets in the 17th century. In Asia, technical analysis is said to be a method developed by Homma Munehis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Analysis
Business analysis is a professional discipline of identifying business needs and determining solutions to business problems. Solutions often include a software-systems development component, but may also consist of process improvements, organizational change or strategic planning and policy development. The person who carries out this task is called a business analyst or BA. Business analysts do not work solely on developing software systems. But work across the organisation, solving business problems in consultation with business stakeholders. Whilst most of the work that business analysts do today relate to software development/solutions, this derives from the ongoing massive changes businesses all over the world are experiencing in their attempts to digitise. Although there are different role definitions, depending upon the organization, there does seem to be an area of common ground where most business analysts work. The responsibilities appear to be: * To investigate busi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Management
Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget. The secondary challenge is to optimize the allocation of necessary inputs and apply them to meet pre-defined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are clearly established, they should influence all decisions made by other people involved in the project – for example, project managers, designers, contractors, and subcontractors. Ill-defined or too tightly prescribed project management objectives are detrimental to decision-ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
