An automated storage and retrieval system ( ASRS or AS/RS) consists of a variety of computer-controlled systems for automatically placing and retrieving loads from defined storage locations. [1] Automated storage and retrieval systems (AS/RS) are typically used in applications where: There is a very high volume of loads being moved into and out ...
Software-defined storage ( SDS) is a marketing term for computer data storage software for policy-based provisioning and management of data storage independent of the underlying hardware. Software-defined storage typically includes a form of storage virtualization to separate the storage hardware from the software that manages it. [1]
Apache Hadoop ( / həˈduːp /) is a collection of open-source software utilities that facilitates using a network of many computers to solve problems involving massive amounts of data and computation. [vague] It provides a software framework for distributed storage and processing of big data using the MapReduce programming model.
In systems engineering, information systems and software engineering, the systems development life cycle ( SDLC ), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. [1] The SDLC concept applies to a range of hardware and software configurations, as a ...
In computer science, persistence refers to the characteristic of state of a system that outlives (persists more than) the process that created it. This is achieved in practice by storing the state as data in computer data storage. Programs have to transfer data to and from storage devices and have to provide mappings from the native programming ...
Reliability, availability and serviceability ( RAS ), also known as reliability, availability, and maintainability ( RAM ), is a computer hardware engineering term involving reliability engineering, high availability, and serviceability design. The phrase was originally used by International Business Machines ( IBM) as a term to describe the ...
In engineering and systems theory, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding.
