Functional programming[ edit ] The principles of modularity and code reuse in practical functional languages are fundamentally the same as in procedural languages, since they both stem from structured programming. Procedures correspond to functions.
Declarative vs Procedural Knowledge Declarative knowledge involves knowing THAT something is the case - that J is the tenth letter of the alphabet, that Paris is the capital of France.
Declarative knowledge is conscious; it can often be verbalized.
Metalinguistic knowledge, or knowledge about a linguistic form, is declarative knowledge. Procedural knowledge involves knowing HOW to do something - ride a bike, for example. We may not be able to explain how we do it.
Procedural knowledge involves implicit learning, which a learner may not be aware of, and may involve being able to use a particular form to understand or produce language without necessarily being able to explain it.
Cognitive models of learning differ in the role they accord to these two types of knowledge: Emergentist models, on the other hand, claim that procedural knowledge can develop without a declarative stage, such that certain types of complex skills can be performed but not explained.
Schmidt's noticing hypothesis claims that learners may apperceive aspects of the target language which are then incorporated into interlanguage as procedural knowledge.procedural language (language) Any programming language in which the programmer specifies an explicit sequences of steps to follow to produce a result (an algorithm).
The term should not be confused with "imperative language" - a language that specifies explicit manipulation of state. An example (non-imperative) procedural language is LOGO, which. Dec 01, · In the case of language development in non-impaired populations, the proposal is that the procedural memory systems support the use and learning of grammar, and the declarative memory system, lexical knowledge (for exceptions see Hartshorne & Ullman, ).
From my understanding, declarative and imperative are two contrasting programming paradigms. Declarative programming (also known as functional programming) languages do not attempt to control the flow of a program; they establish desired results i.e.
. In a procedural language, you define the whole process and provide the steps how to do it.
You just provide orders and define how the process will be served. In a declarative language, you just set the command or order, and let it be on the system how to complete that order.
SQL is declarative language it mean that it lacks components to create new functionalities, for this PL is used to provide functionality of procedural language to SQL as .
Declarative programming contrasts with imperative and procedural programming. Declarative programming is a non-imperative style of programming in which programs describe their desired results without explicitly listing commands or steps that must be performed.
