Systems
Key Points and Objectives
1. Organizations are complex systems composed of interrelated and interdependent subsystems.
2. System and subsystem boundaries and environments have an impact on information system analysis and
design.
3. Systems are described as either open, with free flowing information, or closed with restricted access to
information.
4. A virtual organization is one that has parts of the organization in different physical locations. They use
computer networks and communications technology to work on projects. Advantages of a virtual
organization are:
A. Reduced costs of physical facilities
B. More rapid response to customer needs
C. Flexibility for employees to care for children or aging parents
5. Enterprise systems or Enterprise Resource Planning (ERP) describes an integrated organizational
information system. The software helps the flow of information between the functional areas within the
organization.
6. ERP can affect every aspect of the organization, such as:
A. Design of employees’ work
B. Skills required for job competency
C. Strategic positioning of the company
7. Many issues must be overcome for the ERP installation is to be declared a success:
A. User acceptance
B. Integration with legacy systems and the supply chain
C. Upgrading functionality (and complexity) of ERP modules
D. Reorganizing work life of users and decision makers
E. Expanded reach across several organizations
F. Strategic repositioning of the company
8. A context-level data flow diagram is an important tool for showing data used and information produced by a
system. It provides an overview of the setting or environment the system exists within—which entities
supply and receive data/information.

10. Entity-relationship diagrams help the analyst understand the organizational system and the data stored by the
organization.
11. There are three types of entities:
A. Fundamental entity, describing a person, place, or thing.
B. Associative entity (also called a gerund, junction, intersection, or concatenated entity), joining two
entities. It can only exist between two entities.
C. Attributive entity, to describe attributes and repeating groups.
12. Relationships are shown with a zero or circle representing none, a vertical line representing one, or crow’s
foot representing many and can be:
A. One to one
B. One to many
C. Many to many
13. A use case diagram reflects the view of the system from the perspective of a user outside of the system.
14. A use case model partitions the way the system works into behaviors, services, and responses that are
significant to the users of the system.
15. A use case diagram has symbols for:
A. An actor, the role of a user of the system
B. The use case representing a sequence of transactions in a system
16. There are two kinds of use cases:
A. Primary, the standard flow of events within a system that describe a standard system behavior
B. Use case scenarios that describe variations of the primary use case
17. There are four active behavioral relationships:
A. Communicates—used to connect an actor to a use case.
B. Includes—describes the situation where a use case contains a behavior that is common to
more than one use case.
C. Extends—describes the situation where one use case possesses the behavior that allows
the new use case to handle a variation or exception.
D. Generalizes—implies that one thing is more typical than the other thing.
