Design pattern serves as a solution to common errors during the software development process.
With this pattern, the development team can minimize the effort required to design a solution from scratch every time they encounter a similar challenge.
Overall, it is similar to a blueprint ready for use to solve repetitive design problems during the coding process.
However, it's essential to note that design patterns are not code snippets. It usually resembles structural concepts or guidelines that assist the team in understanding interactions and relationships between objects in a system.
Therefore, it can help developers avoid common design issues, thereby accelerating the overall development process.
Unfortunately, many people still believe that software design patterns and programming algorithms are the same concepts because both provide solutions to coding problems.
However, it's crucial to understand that both have different functions and applications. Algorithms are generally used to outline the steps required to achieve a specific goal.
On the other hand, software design patterns describe solutions at a higher level of abstraction, and you can examine the results of the solution along with the features used.
Here are the elements you should include within the pattern.
In addition to understanding what is a design pattern, it's also crucial for you to note the benefits of these design templates. They are:
For developers, software design patterns are a highly beneficial solution to make code writing more structured and organized by following established design principles.
It provides a clear structure and guidelines for organizing components within a system. Consequently, developers can design a more robust and structured program architecture.
They offer proven and effective problem-solving solutions in software development with high-level approaches.
Code written based on a designated pattern tends to be more readable and evaluable, as it establishes conventions and specific structures that are widely recognized, creating consistency in the code.
Developers can read and understand the code structure without delving into every line in detail.
Software design patterns allow the abstraction of specific components and separate the implementation details from how these components are used.
This enables these components to be reused in various situations without having to change existing code.
Several factors influence the grouping of pattern types, including complexity, details, and the extent of their use. Overall, there are three design pattern types that are most commonly used.
In general, this design pattern type serves to solve problems encountered in the process of creating an object.
Creational patterns focus on how objects and instances are created, making the object initialization process more objective. This pattern can be divided into 5 different categories, namely:
This pattern aims to solve problems in the arrangement of compositions between classes and objects.
In other words, these patterns focus on how classes and objects are combined into a larger and more complex structure. Generally, structural patterns can be divided into 7 other types, namely:
Behavioral patterns can help solve problems in communication between objects. In other words, behavioral patterns offer solutions for organizing control flow between objects and managing dependency relationships within the system. These patterns can be divided into 11 core types, namely:
Patterns at the basic level are often referred to as idioms, which generally apply to a specific programming language.
On the other hand, the most commonly used patterns are called architectural patterns, which can be used in almost all programming languages or even for designing the entire structure of an application.
