Design Patterns to solve programming problems
Learn from mistakes so as not to repeat them in the future is essential to enhance our knowledge and skills, isn’t it? But learn from the mistakes of other professionals to avoid even committing them is even better for those who want to increase productivity and avoid unnecessary efforts. It is with this spirit that we invite you to continue reading this post, in order to get to know the design patterns and what they can do for your company! Want to understand better? Then keep reading our article!
The design patterns are solutions used to solve programming problems often faced by developers when planning a software. They work as a pattern that can be implemented in different programming languages, optimizing the work and helping to deliver good results with less efforts. These patterns help programmers reuse solutions that have proven results, and facilitate communication between the professionals involved in the project.
The design patterns may be structural (when they concern the relationships and associations between objects), creational (related to creating objects for each situation) and behavioral (with focus on communication and responsibilities between the objects). In order to choose the design pattern ideal for a design or functionality, your company can follow the approaches below:
The use of modeling languages such as UML (Unified Modeling Language), is a good way to show the design of the project and understand the interaction between its elements. For this purpose, standardized diagrams are used that expose both the technical issues and business aspects, providing a more comprehensive view of the system.
With this, developers can identify simple and effective ways to address the stages of development, avoiding errors and hassle that may have large impacts in the later stages of the project.
Unlike modeling, brainstroming is a process far more flexible and open. To conduct this procedure, the company should gather the team of developers to discuss the possible patterns for each functionality of the software. In this case, these professionals enrich technical and business discussion with their knowledge, skills and experiences, thus contributing to the identification of appropriate design patterns for each case.
3. Trial and error
Another way to identify design patterns that can help develop is through the method known as trial and error. When using the Test-Driven Development (TDD) method, for example, developers can identify design patterns to be applied as they try to adapt the code to previously developed tests.
Do not forget that the design patterns are more easily found when your company and team reach a high level of abstraction to identify how the solutions adopted in other projects can be fully or partially used in the development of a new code.
