He meant beliefs.
I don't need it defined. But if you ask it is
Specifically, one of some *built-in* type. A low-level abstraction concept typical to early universal purpose programming languages without ADTs, like FORTRAN. Data are aggregated mechanically without further abstraction.
Contemporary use examples are data-oriented domain-specific 4GL, like SQL (data query), Simulink (signal processing). Weak point is presumption of equality of the domain entities and the computational objects and thus 1) built-in types, 2) deduced algorithms from a narrow set (indexing in RDBMS, equation solving in Simulink). This is also the criterion of applicability of a given data-oriented language.
