Question

In the traditional approach to system development, the system stores information about ____. It also refers to an ER diagram to describe sets of things or individual things.

1) objects
2) data stores
3) attributes
4) data entities

Answer 1

The traditional approach to system development involves storing information about data entities, which are represented in ER diagrams as parts of a system without internal structure to simplify design and analysis.

Step-by-step explanation:

In the traditional approach to system development, the system stores information about data entities. When we refer to an ER (Entity-Relationship) diagram, we are describing sets of things or individual things that are elements within a system. These data entities can include objects like books, buildings, roads, machines, and electronic devices, as described in Figure 1.1 which refers to human artifacts. An ER diagram helps model and understand these systems and their properties, consistent with the definition that a model is a representation of a system in the real world.

ER diagrams are essential in systems design for organizing and structuring information. They represent the data entities and illustrate the relationships between them, which is foundational to creating a robust database structure. As per Essential Knowledge 1.A.1 and 5.A.1, in a system, objects or collections of objects are treated as having no internal structure, which simplifies the process of system design and analysis and aligns with the concept of modeling systems to understand their properties without focusing on internal complexity.
