Union type: Science, Unions in various programming languages & Overview

In computer science, a union is a value that may have any of multiple representations or formats within the same area of memory, or a variable that may hold such a data structure. Some programming languages support a union type for such a data type. In other words, a union type specifies the permitted types that may be stored in its instances, e.g.…

How Union type connects Entity context

The extracted context around Union type shows recurring relationship patterns in the source. For example, Union type → In, In COBOL, PERSON-DATA, PERSON-REC, REDEFINES, RENAMES, Since, The, VERS-BYTES, VERS-NUM Another extracted example is Union type → Because JavaScript, However, JavaScript, This, TypeScript, Union, When TypeScript. Use these groups to spot repeated connection types before inspecting the individual relationships.
