The systematic application of engineering to develop software is known as software engineering. It includes designing, implementing, documenting and testing the software. There are numerous sub-disciplines within this field such as software design, software construction and software maintenance. Software designing is the process wherein the components, interfaces and other characteristics of a system are defined. The use of programming, verification, integration testing and a few other processes to create a meaningful and functioning software is known as software construction. Providing cost effective support to software through various activities is known as software maintenance. This book provides significant information of this discipline to help develop a good understanding of software engineering and related fields. Some of the diverse topics covered herein address the varied branches that fall under this category. This book will prove to be immensely beneficial to students and researchers associated with software engineering.
