The branch of engineering associated with software development and testing of products and services is called software engineering. Well defined principles and procedures are used in software development that results in an efficient product. This tutorial includes the basic understanding of software design, product life cycle, and maintenance. Software consists of interconnected programs and the codes are written by developers in any of the programming language. Engineering involves the knowledge to invent, design, build and maintain the software products evolved from the process. Software engineering helps to manage the dynamic nature of the software used in the process.

Why do we need to learn Software Engineering?

Software Engineering helps to manage the software, be it large or small. Without an understanding of software, it is difficult to manage and maintain the same. Proper documentation helps in this process. Also, this helps to manage the software for its better quality.
Software should be scalable according to the need of the hour as it may require different aspects of maintenance and uses. Software engineering helps in this process.
Cost should be managed properly as it affects the maintenance of the product and services. Software engineering helps in cost management as every process is tracked properly and reported to the proper tool.

Applications of Software Engineering

Software engineering develops software for specific business needs that is either needed in daily life or helpful in some other means. It converts the business functions into real time activity. It is helpful in solving business needs.
Software is developed for automation, services, astronomy, stress analysis, design of engines and space shuttles. It also helps in the field of biology and molecular and Nano sciences.
Control systems are used with the help of software to manage and control the hardware devices. Software is used in mobile phones, micro-wave ovens to control the working of the device and this saves time and energy by avoiding mechanical work.
Custom based software can be developed based on specific customer needs. This can be used in the multimedia or graphics field.

Example

In order to run the program ‘Hello World’ identify the approach first and then solves the problem. ‘Hello World’ can be written through echo command or through any text editor. If echo command is used, simply print ‘Hello World’ in one line and the problem is solved.

Prerequisites

People who have a relevant bachelor’s degree and knowledge of computer programming are needed to learn Software Engineering.
Proper focus in any one field is needed to understand the basics and to concentrate in any one particular area.
The knowledge of any one programming language is needed as coding cannot be avoided in the field of software. Also, database knowledge is needed.

Target Audience

The tutorial is intended for people who know at least one programming language and wish to pursue their career in the field of software. Also, students who are learning software engineering, development can follow this tutorial to improve their knowledge.
