IEEE ISO IEC 32430-2021 Software engineering — Trial use standard for software non-functional sizing measurements.
data element type (DET): A unique, non-repeated attribute, which can be in Business Data, Reference Data, or code data. The number of different types of Data Elements of all tables is the number of DETs. Instances of control information are also counted as a DET, such as the “Enter” key to facilitate an external input (EI). database view: The result set of a stored query on the data, which the database users can query just as they would in a persistent database collection object. This pre-established query command is kept in the database dictionary. Unlike ordinary base tables in a relational database, it is a virtual table computed or collated dynamically from data in the database, when access to that view is requested. Changes applied to the data in a relevant underlying table are refected in the data shown in subsequent invocations of the view. elementary process (EP): The smallest unit of activity that is meaningful to the user(s).

NOTE —From ISO/IEC 20926:2009 ed 2.0, Copyright © 2009 IEC Geneva, Switzerland. www .iec .ch. external output (EO): An elementary process (EP) that sends data or control information outside the boundary and includes additional processing logic beyond that of an External Inquiry.
