Which of the following is an object-oriented technology characteristic that permits an enhanced
degree of security over data?
A.
inheritance
B.
Dynamic warehousing
C.
Encapsulation
D.
Polymorphism
Answer: C
Explanation:
Encapsulation is a property of objects, and it prevents accessing either properties or methods that
have not been previously defined as public. This means that any implementation of the behavior of

strategically important systems faster, while reducing development costs and maintaining quality?
A.
Function point analysis
B.
Critical path methodology

The program evaluation review technique (PERT) and critical path methodology (CPM) are both
planning and control techniques, while function point analysis is used for estimating the complexity
of developing business applications.
