Existem várias técnicas que permitem definir os requisitos básicos de um sistema e possibilitam a construção de um modelo de análise orientado a objetos para o sistema. A respeito dessas técnicas, julgue os itens subseqüentes.
A técnica de estrutura do modelo de classes e hierarquias pode utilizar o diagrama de classes da UML e relacionamentos de generalização e especialização para mostrar a estrutura de modelo de classes e as hierarquias entre classes resultantes. O relacionamento de generalização existe entre uma classe geral e classes mais específicas, enquanto o relacionamento de especialização ocorre quando uma mudança na especificação de uma classe pode trazer conseqüências para a outra classe pertencente ao relacionamento.

A modelagem classe-responsabilidade-colaboração fornece mecanismos para identificar e organizar as classes relevantes aos requisitos do sistema. Uma classe cumpre suas responsabilidades de duas maneiras: quando utiliza suas próprias operações ou quando colabora com outras classes.

O modelo comportamental representa aspectos dinâmicos do sistema, além de mostrar as interações ou colaborações entre os vários elementos estruturais. Para isso, a UML define os diagramas de estado, de seqüência, de colaboração e de atividade.

The recent drastic development of agriculture,
together with the growing societal interest in agricultural
practices and their consequences, pose a challenge to
agricultural science. There is a need for rethinking the
general methodology of agricultural research. This paper
takes some steps towards developing a systemic research
methodology that can meet this challenge — a general
self-reflexive methodology that forms a basis for doing
holistic or (with a better term) wholeness-oriented research
and provides appropriate criteria of scientific quality. From
a philosophy of research perspective, science is seen as an
interactive learning process with both a cognitive and a
social communicative aspect. This means, first of all, that
science plays a role in the world that it studies. A science that
influences its own subject area, such as agricultural science,
is named a systemic science. From this perspective, there is
a need to reconsider the role of values in science. Science is
not objective in the sense of being value-free. Values play,
and ought to play, an important role in science — not only in
form of constitutive values such as the norms of good
science, but also in the form of contextual values that enter
into the very process of science. This goes against the
traditional criterion of objectivity. Therefore, reflexive
objectivity is suggested as a new criterion for doing good
science, along with the criterion of relevance. Reflexive
objectivity implies that the communication of science must
include the cognitive context, which comprises the societal,
intentional, and observational context.
