Algorithmic Decomposition Versus Object-Oriented Decomposition



Traditional programming techniques have used algorithmic decomposition. Algorithmic or functional decomposition views software as a process. It decomposes the software into modules that represents steps of a process. These modules are implemented by language constructs such as functions in C. The data structures required to implement the program are a secondary concern, which is addressed after the project has been decomposed into functional modules.

Object-oriented decomposition views software as a set of well-defined objects that model entities in the application domain. These objects interact with each other to form a software system. Functional decomposition is addressed after the system has been decomposed into objects. An object is an entity that performs computations and has a local state. It may therefore be viewed as a combination of data and procedural elements.

Object-oriented approach is a method of implementation in which

1) Objects are the fundamental building blocks.
2) Each object is an instance of some type or class.
3) Classes are related to each other by inheritance relationships.

The principal advantage of object-oriented decomposition is that it encourages the reuse of software. This results in flexible software systems that can evolve as system requirements change. It allows a programmer to use object-oriented programming languages effectively. Object-oriented decomposition is also more intuitive than algorithm-oriented decomposition because objects naturally model entities in the application domain.

Object-oriented design is a design strategy where system designers think in terms of 'things' instead of operations or functions. The executing system is made up of interacting objects that maintain their own local state and provide operations on that state information. They hide information about the representation of the state and hence limit access to it. An object-oriented design process involves
designing the object classes and the relationships between these classes. When the design is realised as an executing program, the required objects are created dynamically using the class definitions.

Object-oriented systems should be maintainable as the objects are independent. They may be understood and modified as stand-alone entities. Changing the implementation of an object or adding services should not affect other system objects. Because objects are associated with things, there is often a clear mapping between real-world entities (such as hardware components) and their controlling objects in the system. This improves the understandability and hence the maintainability of the design.

The two approaches are similar in that both believe that the way to develop a complex system is by using the philosophy of divide-and-conquer; that is break up a complex software design project into a number of simpler subprojects, and then tackle these subprojects individually. The two approaches disagree on how a project should be decomposed.

Cool Tattoo Designs For Arms






For those guys who are interested in getting tattoos, it is most usual that they choose to get tattoos on one of their arms or both. Most often, guys go for a tattoo on both arms are one of the most popular places that guys get cool tattoo designs inked on. Having tattoos on arms are mostly favoured by men because the tattoos can be displayed easily and there are a lot of different designs and sizes that can be placed in several parts of both arms. Whether the design will be placed on the forearm or upper arm, still the designs that you can place on them are endless.

With that being said, what then, are tattoo sleeves? Sleeves are tattooed on the whole length of the arm, or in some instances, only on the upper arm and usually consists of art work that surrounds the entire length of the front arm as well as the entire length of the arm's back. This creates a sleeve effect made of art work. There are some guys who choose to have several cool tattoo designs to make up the sleeve while there are some guys who opt for a single design running the entire length of the arm.

When you decide on which arm tattoo to get done, it is very important to consider just how far up your arm that single tattoo would reach. Consider if the arm tattoo will cover the shoulders too. These are just some of the few things that you would need to think about when you are getting a sleeve tattoo also to be sure that you would be able to make the most out of the tattoo that is being done on you.

Arm tattoos are generally more popular in men than it is for women because of the larger area that the artist would be able to work on in men when it comes to the designing aspect of the tattoo. A man's arms, being a larger area than a woman's is a great place to create an art work that is either a single design or a combination of several designs.

The thing about having cool tattoo designs in the arms or having tattoo sleeves done is that these designs could not be easily completed in one sitting or session. Usually, an artist does the outline of the designs and completes the outline first. And then, within multiple sessions, an artist can slowly fill in the colours and the designs. The most important thing about getting tattoo sleeves from the start until everything is completed is that you have to be sure about the designs that you would have done and that this is something that you are not going to have a change of mind later on. Tattoos are permanent and while there are procedures that make tattoo removal possible, this would normally cause more money, would take longer to do and be more painful than having the tattoo done in the first place.

The Story Of Skull With Horns Tattoo







If you are considering getting a skull with horns tattoo, you should be aware of what sort of statement you will be making with it.

It can cause a lot of different responses from people. Some people, especially teenage boys, choose to get a skull with horns tattoo to present a sort of "bad boy" attitude. They think that girls love dangerous men more than the boy next door. They want to get a skull with horns tattoo because they feel that it will make them appear to be more macho. They think it will add an aura of mystery and danger, which girls will find attractive.

Some people feel that a skull and horns tattoo represents death, danger, destruction and fear. It is a design, which people get, to show power, strength and daringness. However, many of those people do not really understand its origins.

Originally, the skull with horns tattoo was actually not meant to indicate any of those things. In ancient times, a skull with horns actually was a symbol of any sort of major change. It was not meant to represent death or fear directly. However, it may have taken on the representation of death due to the fact that the cycle of life and death is a major change. In fact, it is the biggest change any human being can experience.

This tattoo is known for being somewhat demonic in nature. It is important, if you are going to get such a tattoo design, that you understand the true symbolism behind it. According to the ancient Greek mythological lore, "daimon" means "to express a divine power". It wasn't until the introduction of such religions as Islam, Judaism and Christianity that skulls with horns became known as demonic symbols. Such symbols became associated with the devil. In fact, it was said that the devil could cause madness or sickness within a person's body by taking it over.

You should consider all of these things, if you want to get one. It isn't just about looking cool or attractive. Skull with horns tattoo designs have a lot of history, meaning and symbolism behind them. As with any tattoo, you should do your research before you jump into things with both feet. Be absolutely sure that the skull with horns tattoo is the right tattoo for you and, if it is, enjoy it for years to come!

So you have finally made the decision that you are going to get a tattoo. You have thought carefully and clearly about which cool tattoo design you should go for and you have understood that this is a one time and it is a big time commitment. You certainly would not go through the painful process of getting a tattoo only to change your mind afterward and then end up spending thousands of dollars and going through an even more painful procedure of having it removed.

If you have indeed gone through all that then congratulations and good luck on getting that tattoo. It is certainly a great way of expressing one's unique personality. For those of you, however, who are still stuck on deciding which tattoo design to get, then read on below for some ideas on where you can get a unique and cool tattoo design.

One word about searching for the right design: Research. Choosing the right tattoo for you would indeed require a lot of thought on your part and it is really best for you to think really hard on a specific design that you would get this is to make sure that you will not make a decision that you would go on regretting later on. Remember, the consequences of having a tattoo removed!

There are a lot of resources for tattoo design ideas and you will honestly not run out of ideas, really. What is great is that there are some tattoo design sites that will allow you to combine two different designs so you can create one unique tattoo design that will suit the specific art form that you are looking for. The only important thing is that YOU choose the design. YOU. Not your parents, not your friends, YOU. Deciding on the tattoo design is something that you do not trust any other people with. Well, alright you can ask for advice and ideas but in the end, it would always have to be your call and your decision to make. Since you would be the one who will get stuck with these designs permanently anyway so choose carefully and do not let anyone talk you into agreeing to get a specific design.

Researching for a cool tattoo design would require the utmost time and attention on your end. Make sure that you pore over flash design books at the tattoo artists' studio or you have gone to online tattoo art galleries and checked out various designs. This last suggestion is always often the best because you would be doing it in the comforts of your own home and would not be subjected to unnecessary pressure and unsolicited advice. Do not make random choices and let anyone or anything influence your decision on the tattoo design you would have inked. Again, and I cannot say this often enough, tattoos are permanent. And it is more painful and costly to have it removed. Tattoos are works of art. Tattoo removal scars are unsightly.
