What is Design Pattern?
This is a best practice and problem-solving technic for many software developers. Many common problems faced by software developers at building phase of software can be solved by following design patterns. Contains all the commonly observed errors while working. It’s formalized and flexible to work on.
All errors and trial have a pattern of the solution along with numerous software development over a regular period of intervals. This helps to solve and avoid similar mistakes and errors in developing the software. A step by step approach from programming combination of parameters and algorithms.
In Software engineering design pattern is a general solution of the commonly occurring problems in software designing. It’s not the final code but is a description or template for knowing how to solve a problem in a different situation in building phase of software.
The reusable solutions for the software common problems. All codings were collected and used. A design pattern is famous for C++, Smalltalk, Java, C#, object-oriented languages and many more.
Understanding Design Pattern
They are 3 types of Design patterns
- Structural design patterns made of variables and functions used for
Adapter, Facade, Bridge etc.,
- Creational design patterns made of creating objects and instances within objects used for
Singleton, Factory, Bridge etc.,
- Behavioral design patterns made for the interaction of one class with the other class used for
Strategy, Observer, Iterator etc.,
Few other design patterns which come for enterprise application
- MVC design pattern
- Dependency injection design pattern
All these help in building a good structured and professional interfaced software’s.
How does Design Pattern make working so easy?
It provides tested, proven paradigms, development codes which help software engineers to speed up their development process and also solve the common coding mistakes and problems.
Effective software design requirement raised and fixed issues suitable to the design will be visible until later in the implementation. Applying design patterns help in resolving the issues which solve and improve codes, readability for codes and look design of software architect familiar with patterns.
Helps in applying creative design technique to certain problems. It provide simple and general solutions, documented in a usable format to pick specific suitable codes to solve particular software design problems.
There are many companies which offer jobs
- Mindgen Solutions
- Hexaware Technologies
- 1mg Technologies
- Huawei Technologies
And many more companies have good packages for the software developers with the skill and hands-on experience on Design Pattern.
What can you do with Design Pattern?
- It helps in the development phase of any software by providing solutions for the common mistakes made by developers while working. Well-Established industrial standards and industrial approaches can be maintained while creating software with fewer chances of failure.
- It is a template to code and can be used directly or can be modified with codes as per development project requirements, and it’s language-independent is flexible to use for any type of language codings for suitable output.
Working with design Pattern
- Working with it brings the smarter way of creating and developing software application and tools along with the latest codes used in the technology, Adds professional values to the experienced and junior software designing and development experts.
- It helps in keeping the software simple and easy to understand which avoid complex codes which lead to lose the simplicity. Onetime simple classes help in opening and working the application fast with good user experience.
- Suggests to remove unwanted codes in a process and makes codes flexible enough and using design pattern code is easy to maintain, understand and extend.
- Focus on a loosely couple code to add flexibility in modifying the application as per users need with its version wise improvements, testing is easy and chances of bugs will also be less if we use Loosely couple codes.
- Design the application software first once the stricture and features of applications are finalized then start coding to avoid disturbance in the developing phase. Use of effect codes with really needs the be in the application.
- Need to have basic knowledge of coding.
- Know at least 1 professional language as part of semester syllabus in CSE, IT and any other equant computer graduation courses.
- Knowledge of design strictures of software application and tools.
Why should we use Design Pattern?
- The IT industrial code is never small they contain the huge data and Robust code can be handled easily using design patterns, codes can be reused as per requirement and is highly maintainable which reduces the cost of ownership.
- Easy to handle the codes, maintain and in case of any errors we can quickly identify the area and fix it with less time the systemic approach to fixing problems is easy. Loosely coupled application avoid many changes in the application while fixing.
- It is the high professional required skill and has demand in the market for those who can create interactive and best user-friendly applicant for clients.
- It also deals with the change at a run time with more dynamic. Class scope is defined as the design time of built, structure and creating relationships with classes with the runtime.
Why do we need Design Pattern?
- As developers, we have many ways for coding in which we have common problems as per industrial standards and ways to do things correctly all this issue will be taken care of by Design pattern. Creating Class, modifying and creating instantiates, an interaction of Objects in software, using smart and latest codes.
- It helps in passing data from one object to other, calling functions, using different patterns for fixing the connections between objects. Helps in writing loosely coupled codes to maintain software flexible and easy to maintain, writing good reusable codes to use as per needs of the software.
Who is the right audience for learning Design Pattern technologies?
- CSE and IT graduates who want to make their mark in the development area of the software designing and coding can join this course.
- Even the experienced software developers can also do this course for upgrading them self with technology and also to apply the professional’s experience to design best design patterns for the application.
- Design pattern helps in creating an interactive software application with simple, easy and loose codes which help in making best user-friendly applications and update its versions easily with the latest requirements.
