The International Bureau of Weights and Measures (BIPM) is responsible for ensuring the standardization of the use of units of measurement in the measurement of weights and measures, as well as the definition and application of these in everyday life. real scalar […]

UML diagram

provides the data structure for data templates using objects, collections and relationships between them. The multiplicities in the UML diagram specify the range of allowablecardinality values, giving a specification of a data template within a data dictionary BS EN ISO 23387:2020

data template

schema providing a data structure used to describe the properties of objects NOTE The relevant scope of the data template should be used together with the term “data template”. E.g. a data template for a product should be named “product data template”. A data template for a system should be named “system data template”, etc. […]
