Tipo de Dados Abstrato (ADT)
An Tipo de Dados Abstrato (ADT) is a theoretical concept in ciência da computação used to define estruturas de dados based on their behavior from the point of view of a user, specifically the operations that can be performed on the data and the types of values it can hold. Unlike concrete tipos de dados, which specify how data is stored and manipulated at a low level, ADTs focus on what operations are available and how they can be used.
Por exemplo, uma Pilha is an ADT that allows operations like push (adding an item) and pop (removing the most recently added item). The user of a stack does not need to know how these operations are implemented; they just need to understand that the stack operates on a last-in, first-out (LIFO) principle.
Os ADTs ajudam programadores e desenvolvedores a design systems and applications by providing a clear interface for data manipulation, thus promoting better code organization and separation of concerns. They are often implemented in various linguagens de programação using classes, interfaces, or modules, which encapsulate the data and the operations that can be performed on it.
Em resumo, enquanto os ADTs fornecem uma maneira de definir tipos de dados de forma de alto nível, eles não ditam como esses tipos de dados devem ser implementados. Essa abstração permite flexibilidade na implementação, garantindo que as operações permaneçam consistentes e confiáveis.
