3.1

data

reinterpretable representation of information (3.3) in a formalized manner suitable for communication, interpretation, or processing

[SOURCE: ISO/IEC 2382:2015, 2121272]

3.2

reference architecture

authoritative source of information about a specific subject area that guides and constrains the instantiations of multiple architectures and solutions

Note 1 to entry: This document utilizes the definition of reference architecture from DoD “reference architecture description”^[7].

Note 2 to entry: Reference architectures generally serve as a foundation for solution architectures and can also be used for comparison and alignment of instantiations of architectures and solutions.

3.3

information

data (3.1) that are processed, organized and correlated to produce meaning

Note 1 to entry: Information concerns facts, concepts, objects, events, ideas, processes, etc.

3.4

activity

specified pursuit or set of tasks

[SOURCE: ISO/IEC 17789:2014, 3.2.1]

3.5

knowledge

maintained, processed, and interpreted information (3.3)

[SOURCE: ISO 5127:2017, 3.1.1.17]

3.6

functional component

functional building block needed to engage in an activity (3.4) , backed by an implementation

[SOURCE: ISO/IEC 17789:2014, 3.2.3]

3.7

data governance

property or ability that needs to be coordinated and implemented by a set of activities (3.4) aimed to design, implement and monitoring a strategic plan fordata asset management

Note 1 to entry: Governance of data is described in ISO/IEC 38505-1.

Note 2 to entry: Data asset is understood as a set of data items, or data entities, that have a real or potential benefit for an organization. Data asset is a subset of asset defined in ISO 55000. A benefit is an advantage to the organization of the actionable knowledge derived from an analytic system. It is often ascribed to big data due to the understanding that data has potential benefit that was typically not considered previously.

Note 3 to entry: A strategic plan for data asset management is a document specifying how data management (3.15) is to be aligned to the organizational strategy. This term has the same meaning as strategic asset management plan (SAMP) defined in ISO 55000 with data point of view.

3.8

data quality

degree to which the characteristics of data satisfy stated and implied needs when used under specified conditions

[SOURCE: ISO/IEC 25024:2015, 4.11]

3.9

data quality management

coordinated activities to direct and control an organization with regard to data quality

[SOURCE: ISO 8000-2:2018, 3.4.9]

3.10

party

natural person or legal person, whether or not incorporated, or a group of either

[SOURCE: ISO/IEC 17789:2014, 7.2.3]

3.11

policy

intention and direction of an organization as formally expressed by its top management

[SOURCE: ISO 55000:2014, 3.1.18, modified — The term has been changed to the singular form and the final stop has been removed from the definition.]

3.12

role

set of activities (3.4) that serves a common purpose

[SOURCE: ISO/IEC 17789:2014, 3.2.7]

3.13

stream

list of flow objects attached to a port of a flow object

[SOURCE: ISO/IEC 10179:1996, 4.33, modified — by deleting leading article and trailing full stop.]

3.14

sub-role

subset of the activities (3.4) of a given role (3.12)

[SOURCE: ISO/IEC 17789:2014, 3.2.9]

3.15

data management

set of activities (3.4) aimed to implement the big data architecture that best meet business goals by following the strategic plan for data management assessment

3.16

data lifecycle

stages in the management of a data

Note 1 to entry: The target of lifecycle (defined in ISO 55000) is data in this document.

3.17

application programming interface

API

boundary across which application software uses facilities of programming languages to invoke services

[SOURCE: ISO/IEC 18012-2:2012, 3.1.4, modified — Note 1 to entry has been removed and the final stop has been deleted from the definition.]
