General Concepts about Object-Oriented Programming

The programming style that we usually call object-oriented programming (OOP) has appeared relatively recently in the history of programming languages. This is a particular and very convenient style for many situations. It was designed to overcome the limits of structured programming based mainly on the widespread use of procedures, functions, pointers or other more or less developed data types.

Although structured programming is very practical for small software systems or reduced non-graphic applications, it should be avoided when dealing with large applications that use graphic elements where object-oriented programming is recommended. Object orientation means organizing software resources as a collection of distinct and discrete objects, which includes both data structures and their processing functions. This organization is an extension of structured programming in which the data structures and processing functions are only loosely connected. All items have their own identity and are perfectly distinct.

An object is defined as an abstract concept, a specific and useful element for any application. Objects serve two specific purposes:

– they provide a better understanding of the problem to be solved;

– they provide a base design for implementation.

A class of objects encapsulates a certain number of objects with similar properties. This similarity refers to both the description (data and attributes) and the behavior (functions or methods). Attributes are unique features within an object class. Each attribute receives a certain value which can be modified during the objects life cycle. Two or more objects can have the same or different values for the same attribute.

Methods or operations are processing functions applied to objects of a certain class. All objects within a class admit the same set of methods, methods which in return may receive any number of additional parameters. In order to apply various methods to an object, it has to be created (defined). Defining an object is called instantiation. Once an object has fulfilled its mission it is removed.

Abstraction is a fundamental human trait that allows us to build models and thus cope with complexity. In every field of human activity, project approach is based on building a model for a better understanding of the problem to solve. Software engineering makes no exception. Through abstraction the essential key aspects are isolated from the non-essential ones. Therefore, each problem might have several adequate models.

In the software engineering industry, structured programming has made a big step forward defining three perspectives needed in order to properly address any application. These perspectives, also known as models, are: the static model, the dynamic model and the functional model.

There are currently several object-oriented methodologies used for analysis, design and implementation of software resources. One of these modeling methodology is the OMT (Object Modeling Technique) methodology. This method of modeling involves the planning of the various development stages and a graphical representation of objects and their relationships.


The Law of Attraction – The Real Science of Getting Rich

If you’ve been paying attention to the personal development industry in the past few years then you must have heard about the law of attraction. Thanks to the movie ‘The Secret’ the law of attraction has become a household name. The truth is that this law has been known by most success teachers for years. However, it is only now that it has become common knowledge. In this article I will explain what the law of attraction really is and how it is truly the science of getting rich.

So what is the law of attraction?

You will find many definitions about this law, however, the simple and basic explanation is that this law is all about harmony. I call it the ‘harmony effect’. The harmony effect simply states that you draw to you whatever you are in harmony with and that is exactly what the law of attraction does. It draws to you everything that is in harmony with you.

So what this means is that a rich person is in harmony with money, a poor person is in harmony with poverty, a sick person is in harmony with sickness, a healthy person is in harmony with health and so on and so forth. By understanding this simple explanation you realize that you do not necessarily attract what is like you or unlike you. You simply attract what is in harmony with you. This is the secret to understanding the law of attraction.

How many times have you met people who had something you wanted and you wondered why they had it and you didn’t. You might think that you deserve more than they do but what you have to understand is that to get what you want you need to get in harmony with it. Those people you see who have the things you want are simply in harmony with them. The law works perfectly and it’s universal in its application.

How to use the law of attraction effectively:

1 – Know what you want

2 – Focus predominantly on what you want (not what you dislike or are unhappy about)

3 – Take action

As you can see the law of attraction is a simple law that can easily be misunderstood. By reading this article you should now know that the law of attraction is all about harmony. Nothing more nothing less. Your job is to know what you want, focus on it and allow the law to bring you people, places and circumstances that will eventually lead you in the direction of what you want.


Hazards Of Computer Security

Computer security hazards are a constant and never ending concern for information security managers, especially due to the increasingly deceptive modes of theft and hacking that are being created and developed. When it comes to security for computers, their programs and the information that you are protecting, there is never a moment where you want to find your organization or the management systems it uses are vulnerable or at risk. For this reason, it is crucial that you are always up to date on industry practices and norms, so that you can implement these new and revised techniques with each computer security hazard as they arise and to prevent future instances.

Any training you take to learn to manage computer security hazards and threats for a company and organization should provide you with a comprehensive education on the different types of threats possible, as well as how they function, how to prevent and detect them and how to fix the damage they can cause. You will also need to be informed off the way in which networks operate in order to create the most secure for your company, or if one is already in use, to know how it operates and how to reduce the security hazards that you might face.

Perhaps the most important and useful training you can receive is how to relay risk reduction and management skills to other individuals within the company. The biggest hazard to an organization’s network is the individuals that will be using it daily, and all of these people will need to be made aware of measures that need to be taken and educated in your network’s ability to deal with specific threats. This form of education and management is a vital role in reducing the hazards that can potentially plague the computer security of your firm, which is why it requires full time management. If you are able to combine your technical skills with great people and communication skills, this might be the best role for yourself in the field and present more opportunities for you career wise.

If you are considering a career in computer security management, training on the hazards to these networks is an important and integral part of that education. Because it is a field that is high in demand, the career possibilities and opportunities are great. Invest the time and energy in educating yourself about all aspects of this path in order to give yourself the best advantage when it comes time to look for employment. Employers are always looking for individuals with a wide breadth of understanding and knowledge surrounding the networks that they create to best serve their clients in order to grow and remain successful.

Examples Of Science Fair Projects

Examples of Science Fair Projects

Part of the preparation that is completed by the teaching staff in readying a science fair event is presenting the ideas to the students. Some students are very interested in these types of extracurricular events and other students would just as soon remain anonymous in the back row of the class. This aspect of preparation involves a sales pitch of sorts from the teacher. She or he must present the idea to the class while fostering the encouragement for the students to participate. The prizes and recognition will motivate some students and other students will be motivated by the opportunity to explore some topic that interests them. The latter set of students will need little encouragement and former group will likely retain enough interest to at least consider what the teacher is presenting. One way to sell the class on these events is to show them examples of science fair projects.

One of the most effective examples of science fair projects is the stink bomb.
If students were to rank their favorite among the examples of science fair projects, this smelly chemical reaction would be in the number one position. There are two reasons for using this example of science fair projects. The first is to get the attention of the students hiding on the back row and convince the others that this can be a fun and enjoyable process. There is nothing quite like a demonstration to win over a crowd of less than enthusiastic teenagers! The second reason is that if you use this example of a science fair project in class then the students cannot use it in the science fair. This clever reason prevents all the mischievous students from showing up to the science fair with all manner of smelly projects. By using this as examples of science fair projects in class you take it off the table as a possibility for student experiments.

Once the teacher has gotten the attention of the whole class and the neighboring classes down the hall with the stink bomb, she or he should have no trouble signing up the students for this event! Once this is done the students can begin discussing what topics they would like to demonstrate at the now popular school science fair.
