  2. Data processing - Wikipedia

    en.wikipedia.org/wiki/Data_processing

    A data processing system is a combination of machines, people, and processes that for a set of inputs produces a defined set of outputs. The inputs and outputs are interpreted as data, facts, information etc. depending on the interpreter's relation to the system. A term commonly used synonymously with data or storage (codes) processing system ...

    en.wikipedia.org/wiki/Data-flow_diagram

    Data-flow diagram. A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system ). The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow — there are no decision rules and no loops.

    en.wikipedia.org/wiki/Process_(computing)

    Process (computing) In computing, a process is the instance of a computer program that is being executed by one or many threads. There are many different process models, some of which are light weight, but almost all processes (even entire virtual machines) are rooted in an operating system (OS) process which comprises the program code ...

  7. Data engineering - Wikipedia

    en.wikipedia.org/wiki/Data_engineering

    Data engineering. Data engineering refers to the building of systems to enable the collection and usage of data. This data is usually used to enable subsequent analysis and data science; which often involves machine learning. [1] [2] Making the data usable usually involves substantial compute and storage, as well as data processing .

  8. Electronic data processing - Wikipedia

    en.wikipedia.org/wiki/Electronic_data_processing

    Electronic data processing ( EDP) or business information processing can refer to the use of automated methods to process commercial data. Typically, this uses relatively simple, repetitive activities to process large volumes of similar information. For example: stock updates applied to an inventory, banking transactions applied to account and ...

  9. Data system - Wikipedia

    en.wikipedia.org/wiki/Data_system

    Data system. Data system is a term used to refer to an organized collection of symbols and processes that may be used to operate on such symbols. [1] [2] Any organised collection of symbols and symbol-manipulating operations can be considered a data system. Hence, human-speech analysed at the level of phonemes can be considered a data system as ...
