Self-contained System (software)
In computing, self-contained system (SCS) is a software architecture approach that focuses on a separation of the functionality into many independent systems, making the complete logical system a collaboration of many smaller software systems. Self-contained system characteristics SCS have certain characteristics: #Each SCS is an autonomous web application. #Each SCS is owned by one team. #Communication with other SCSs or third-party systems is asynchronous wherever possible. #An SCS can have an optional service API. #Each SCS must include data and logic. #An SCS should make its features usable to end-users by its own UI. #To avoid tight coupling an SCS should share no business code with other SCSs. #Shared infrastructure should be reduced to increase availability and decrease coupling. Implementations create larger systems using this approach – in particular web applications. There are many case studies and further links available. Self-contained systems and microservice ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and development of both hardware and software. Computing has scientific, engineering, mathematical, technological and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology and software engineering. The term "computing" is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathematical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Architecture
Software architecture is the fundamental structure of a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. The ''architecture'' of a software system is a metaphor, analogous to the architecture of a building. It functions as a blueprint for the system and the developing project, which project management can later use to extrapolate the tasks necessary to be executed by the teams and people involved. Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. For example, the systems that controlled the Space Shuttle launch vehicle had the requirement of being very fast and very reliable. Therefore, an appropriate real-time computing language would need to be chosen. Additiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microservices
A microservice architecture – a variant of the service-oriented architecture structural style – is an architectural pattern that arranges an application as a collection of loosely-coupled, fine-grained services, communicating through lightweight protocols. One of its goals is that teams can develop and deploy their services independently of others. This is achieved by the reduction of several dependencies in the code base, allowing for developers to evolve their services with limited restrictions from users, and for additional complexity to be hidden from users. As a consequence, organizations are able to develop software with fast growth and size, as well as use off-the-shelf services more easily. Communication requirements are reduced. These benefits come at a cost to maintaining the decoupling. Interfaces need to be designed carefully and treated as a public API. One technique that is used is having multiple interfaces on the same service, or multiple versions of the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galeria Kaufhof
Galeria Kaufhof GmbH was a German department store chain, headquartered in Cologne. It was a member of the International Association of Department Stores from 1930 to 2010, with various CEOs acting as presidents of the Association over time. Until 30 September 2015, the company was a subsidiary of Metro AG, when the company announced that it had been acquired by Hudson's Bay Company. In September 2018 they announced plans to merge with their largest competitor Karstadt. In June 2019 all the shares of Galeria Kaufhof were bought by the Austrian company Signa Holding, who been the partner in the former merger. On March 25, 2019 Karstadt & Galeria Kaufhof launched their merged company, Galeria Karstadt Kaufhof Galeria Karstadt Kaufhof GmbH, based in Essen, Germany, is the second largest department store group in Europe, with 131 locations and 18,000 employees. The company was formed in 2018 with the merger of two of Germany's most historic department sto ..., based in Essen, with ...
