Using Patterns To Define A Software Solution
Introduction
Introduction
All evolved engineering disciplines follow certain distinct patterns. Understanding and applying these patterns can benefit in many ways. For example, it can provide software architects and designers the means for designing robust solutions quickly using proven techniques. Patterns also provide a means of ensuring better communication among professionals involved in the same capacity.
A Brief History of Software Patterns
Object-oriented patterns for software engineering came into spotlight in the 1990s and the topic became a mainstream subject with the publication of Design Patterns: Elements of Reusable Object-Oriented Software [GOF] in 1995. Since then, software patterns and software development services have become a major area of study and an industry in itself.
Learning to Think in Patterns
A very important step in learning to think in patterns is to start learning the vocabulary pertaining to a specific domain. This can be achieved by extensive study of material covering the subject. Design Patterns: Elements of Reusable Object-Oriented Software [GOF] is an excellent resource to get you started.
Defining a Solution with Patterns
It requires a good deal of abstract thinking for using patterns to define a software solution. Along with other cross-solution issues like security and logging, a software developer must define the following aspects (most of the Indian software developers keep these steps it mind):
1. The boundaries of the solution
2. The structure of the solution
3. The frameworks that support the solution's domain
Defining the Solution's Boundaries
This is the first step in defining a software solution. It adds focus to the solution and also permits the solution to be designed and developed. It is derived at from system requirements stated by the client, understanding process dependencies and subjective observations of the developer. Developers involved in software programming in India rely with the facts.
Defining the Solution's Structure
The structure of the solution, which comes next, provides a conceptual understanding of the solution space. The architectural framework will help ensure consistency throughout the solution, with a goal of making it more extensible and maintainable.
Defining the Domain Frameworks
After defining the solutions structure, the next step involves defining the frameworks within that structure. In some very complex solutions, multiple frameworks are required to fulfill the functional requirements.
Defining frameworks begins with understanding the objects and relationships within the context of the problem domain. For complex scenarios, the domain can be divided up into subdomains, each resulting in a separate framework.
Design Patterns [GOF] categorizes patterns into three types:
1. structural,
2. behavioral,
3. and creational.
Looking at the solution requirements, the solution's architectural structure, and the analysis models in the context of these categories is a good way to begin defining the domain frameworks.
Conclusion
Patterns are an important tool in the analysis and design of a software solution. They also give the architect the ability to conceptualize a solution at different levels and provide a valuable way of communicating concepts.
