In other words, we should write our components so that users avoid using pointers (yuck!), and it is clear who is resposible for managing what data. The consequences of not doing this properly can result in headaches Value Semantics and Polymorphism Lately I've been interested in formalising the notion of value semantics for one reason or another. I've been in email conversations with other people who have been interested in making value semantics and value-oriented programming the norm in C++. In formal semantics, truth-value semantics is an alternative to Tarskian semantics. It has been primarily championed by Ruth Barcan Marcus, H. Leblanc, and M. Dunn and N. Belnap. It is also called the substitution interpretation (of the quantifiers) or substitutional quantification.. The idea of these semantics is that universal (existential) quantifier may be read as a conjunction The session-level value of NLS_LENGTH_SEMANTICS specifies the default length semantics to use for VARCHAR2 and CHAR table columns, user-defined object attributes, and PL/SQL variables in database objects created in the session.

Semantic values are entities assigned to expressions by theories in order to account for semantic features of languages, such as truth conditions and inferential  Time dependents of the begin value will behave as though the element had begun earlier.

In C++, you can pick and choose where you want reference semantics (pointers/references) and where you'd like value semantics (where objects physically contain other objects etc). 2020-04-25 Definitions.

Value semantics for an object indicates that only its value is important. Its identity is irrelevant. The alternative is reference/pointer semantics; the identity of the object is at least as important as the value of the object. This terminology is closely related to pass/copy-by-value and pass-by-reference.
