JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD B.Tech IV HUMAN COMPUTER INTERACTION Previous Question Paper (September - 2020 - R16)
Answer any Five Questions. All Questions Carry Equal Marks.
Main
Discuss the following object relationships with examples.
Collection
Answer
A Collection relationship represents a group of objects that are treated as a single unit or set, even though they remain distinct entities. It implies that the objects share a common characteristic or purpose but do not necessarily have a hierarchical dependency. For example, a folder containing various unrelated documents or a list of selected files in a file explorer represents a collection.
Container
Answer
A Container relationship defines a physical or logical boundary where one object holds or encloses one or more other objects. The container dictates the spatial context for its contents, and moving or deleting the container typically affects all contained items. An example is a window in a graphical user interface that acts as a container for buttons, text fields, and labels; if the window is closed, all its contents are removed from the screen.
