A record is similar to a mathematical tuple, although a tuple may or may not be considered a record, and vice versa, depending on conventions and the programming language. In the same vein, a record type can be viewed as the computer language analog of the Cartesian product of two or more mathematical sets , or the implementation of an abstract ...
The individual fields in a record may be accessed by name, just like any variable in a computer program. [3] Each field in a record has two components. One component is the field's datatype declaration. The other component is the field's identifier. [4]
In computer science, a literal is a textual representation (notation) of a value as it is written in source code. [1] [2] Almost all programming languages have notations for atomic values such as integers, floating-point numbers, and strings, and usually for Booleans and characters; some also have notations for elements of enumerated types and compound values such as arrays, records, and objects.
Transcript (law), a verbatim record of some proceedings, in particular a court transcript is a record of a law court case or similar procedure; Archaeological record, the body of archaeological evidence; Recorded history, a record of events that has been made for thousands of years in one form or another, e.g., oral, photographic, or written
In most programming languages (exceptions include Ruby), primitive types such as double, float, int, long, etc. simply store their values somewhere in the computer's memory (often the call stack). By using simple assignment, you can copy the contents of the variable to another one: Copying primitive types in Java or C++:
In computer science [citation needed], a storage record is: A group of related data, words, or fields treated as a meaningful unit; for instance, a Name, Address, and Telephone Number can be a "Personal Record". A self-contained collection of information about a single object; a record is made up of a number of distinct items, called fields.

Many languages allow generic copying by one or either strategy, defining either one copy operation or separate shallow copy and deep copy operations. [1] Note that even shallower is to use a reference to the existing object A, in which case there is no new object, only a new reference. The terminology of shallow copy and deep copy dates to ...
