Question

Quizplus · Accepted Answer

A composition is a design principle in object-oriented programming where a part object is part of only one whole object and it is created and destroyed along with the whole object. This is in contrast to aggregation, where the part object can belong to multiple whole objects and can exist even if the whole object is destroyed. Dependent refers to objects that rely on other objects or entities, weak entity refers to an entity in a database that cannot be uniquely identified without the help of another entity, and declarative refers to a programming paradigm where instead of specifying the steps to execute, the programmer specifies the desired outcome or goal.
