Gang Of Four Design Pattern Analysis

Object Oriental Analysis Design is a hands on approach used to model and create systems as a group of interacting objects. The term “Object”, describes a form of entity or “thing” of concern. Objects are typically modeled after real world entities or concepts. For the business analyst, examples of objects may range from; invoice, product, contract, etc. Objects usually contain attributes that can be set to specific values. With Object Oriented Approach to system design, it tries to lessen the impact of problems by combining related data and functions into the same module. Objects In the real world can be characterized by two things; data and behavior. For example, a television is an object and possess data in the sense that it is tuned to a particular channel, the scan rate is set to a certain value, the contrast and brightness is a particular value and so on. The television object can also "do" things. The television can switch on and off, the channel can be changed, and so on. Below is a graphical representation of a single object and its characteristics:

In the object-oriented modelling class diagrams are very important. In data modelling techniques class diagrams are used. These class diagrams are represented by using the box symbol.

One to one, one to many and many to many: These three relationship types. One to one is where one piece of data is exchanged with another one. One to many is where piece of data is exchanged with many pieces of data. Many to many is where lots of pieces of data is exchanged with lots of other pieces of data.

The Oxford Dictionary of Sociology Defines structure as “A term referring to any recurring pattern of social behaviour or, more specifically, to the ordered interrelationships between different elements of a social system or society… It is sometimes used rather loosely to refer to any observable ‘pattern’ of social activities” More simply put, structure is the

nodes in a data structure, determined by node type or class. The advantage of this pattern

Archetypes are patterns from which other elements or ideas are derived. It can be something physical or symbolic, always capable of generating something more from themselves. You can also consider the archetype as an example. From the archetype, they shape behaviors and ways of thinking that are constructed by imitation or in search of similarity.

Let’s begin with the first of the five-structural configuration which is simple structure, simple structure is made up of a very small groups of procedural and provision staff members that

Inheritance is when a class (subclass) has the same attributes and methods of another class (parent class); this is done by creating class from an existing class. While a subclass has properties derived for the parent class, it can also have properties of its own.

The seven types of patterns are Series, Spree, Hot Prey, Hot Spot, Hot Setting, Hot Place, and Hot Product.

A hierarchical data structure is implemented using multilinked lists that contain scalar items, vectors, and possibly, n-dimensional spaces.Stack is a conceptual model of a data structure that can be implemented as a vector or a linked

The author supports the thesis through the utilization of examples of in class instruction implementation of pattern books.

It lays out a specific pattern that heightens students capability to learn: prepare, teach one another, and ponder/prove.

Lesson 3.1 is a review of the low-level constructs that we use to store and

Programming languages are vast and diverse in their numbers. These different languages use fundamental styles of programming called programming paradigms. These programming paradigms layout the particular design approach that a program will use to solve a problem or achieve an objective. Of the many different types of programming paradigms, some of the more distinguished ones are procedural, functional, logical, and object orientated programming. Recently the object orientated languages have been rising in popularity due to their ability to easily implement large programs. There are many different object orientated programming languages (OOPLs), among them are C#, Java, Ruby, and Python. This essay will compare and contrast two of these languages: Python and Java.

Sorts of Structures: There are essentially two sorts of structures i.e. Formal and Informal. Formal structure is received by bigger associations where every single individual has some particular undertakings and obligations which ought to be entirely taken
