Understanding Unified Modeling Language (UML)

Understanding Unified Modeling Language (UML)


UML is the de-facto standard for modeling Object Oriented software.

UML allows software engineers to document models in a way that supports scalability. UML modeling raises the level of abstraction throughout the analysis and design process. UML modeling facilitates the creation of modular designs resulting in components and component libraries that expedite development.

The UML architecture is based on the Meta-Object Facility (MOF). The MOF defines the foundation for creating modeling languages used for object modeling (UML), and ...

Big O Notation

What is “Big O” Notation?

Big O notation: Indicates the worse-case run time for an algorithm–that is, how hard an algorithm may have to work to solve a problem.

Big O example:

Suppose an algorithm is designed to test whether the first element of an array is equal to the second. If the array has 10 elements, this algorithm requries one comparison. If the array has 15,000 elements, it still requires one comparison. In fact, the algorithm is completely independent of ...

Pythagorean Triple
A right triangle can have sides whose lengths are all integers.
The set of three integer values for the lengths of the sides of a right triangle
is called a Pythagorean Triple. The lengths of three sides must satisfy the relationship that the sum of the
squares of two of the sides is equal to ...
