A solution to any software problem can be best found in various types of software patterns which are stable and reusable. The solution to a lot of software problems is devised into a design or template that can be used as a continuous tool of problem solving. They are designed keeping in mind the common technical errors and also the needs and requirements of the various users of these softwares. Also, several types of software patterns are far-fetched taking into account problems that crop up after the initial stages of implementation of any software. Software patterns are flexible and easy to handle which makes the job of software engineers easier in dealing with a technical breakdown.
There are different types of software patterns designed to cater to different problems. Some of them are analysis patterns, architectural patterns and organisational patterns. The working and need of each is unique with different focus areas. It is of absolute importance for a designer to be aware of the role that a software pattern can play in a particular application or programme.
Design patterns are the most commonly used software patterns. They facilitate interactions between class and objects and do not cater to problems of gigantic magnitude. Arriving at general and practical solutions to real-world problems is what design patterns do while operating in the form of templates. This type of software pattern can be further categorised into creational, structural and behavioural patterns with different area of specialization. Creational patterns are generally concerned with the creation of an object for a problem while taking advantage of polymorphism. Structural patterns adapt themselves as per the structure and purpose of the software. The interpretation of exchanges between objects comes under the ambit of behavioural pattern. Some examples of design patterns include the intermediary pattern that acts like a transmission agent. Another example can be the traversal pattern.
The very concept of design patterns has been subject to the criticism of many. While someone advocates a more formal approach in the formulation of a design pattern while others complain that it leads to avoidable duplicity of codes. There is also a considerable section of people who have failed to note vast differences between the design and architectural patterns.
The conceptual aspects of a business model can be best conveyed through analysis pattern. There are certain developmental problems which are usually faced by software organisations and organisational or process patterns come to the rescue in such cases. Thus, we have many types of software patterns which deal with different problems.
Patterns are derived from a working design and are not always object-oriented. However, easy and flexible they are to use, developing a software pattern is never an easy task and requires time, expertise and hard-work. It is important for a person to be in sync with each and every aspect of a software pattern before applying it to a problem. The conceptual understanding forms the very basis of successful problem-solving. The types of software patterns available today do help to ease out the complexities that need to be tackled when software breaks down. There is always a scope of improvements and innovations are more than welcome.
