Professional Software Development | CST309 | MSS MODULE 1 | KTU | Anna Thomas | SJCET

We are going to look at MSS module 1, the first topic Professional Software Engineer So our first question, what is a software? We know that software is a combination of computer programs and associated documentation So when we go to work, most of the people are going to get the designation of software engineer So according to the requirement of a user, it is your responsibility to design and develop the software So what is a software or management of a software is very important Now, what are the attributes of good software? So the first attribute of good software is functionality That is, if a user says that he wants a function, a developer should be able to produce it completely A good software should be able to maintain the performance as much as the user expects And after this, it should be easy for us to maintain and use it Next question, what is software engineering? So this software production, development, testing, helps in these areas The entire section that concerns this discipline is called software engineering There are four fundamental activities in this Specification, Development, Validation and Evolution So these four are what we study in this module Next, what is the difference between software engineering and computer science? Computer science focuses more on theories and fundamentals Software engineering focuses more on practicalities The difference between software and system engineering is System engineering focuses more on system development, computer-based system development If you say system engineering, hardware and software will come Software engineering is only a part of system engineering What are the key challenges faced in software engineering? First one is, we have to be able to accommodate a variety of requests from customers Also, we have to be able to deliver a deadline We have to be able to deliver a system without compromising any function What are the costs of software engineering? 60% development cost and 40% testing cost What are the best software engineering techniques and methods? What differences has the web made to the software engineering? Next is software products There are two types of software products One is generic and the other is customized From the name itself, generic is a standalone system That is, it is a system developed by a particular organization It is common to all If it is an application for a mobile device or a software for a PC Generally, people classify generic products There is no customizability It exists as it is Customized software is designed for a particular customer For example, it can be a control system for an electronic device It can be a software for a particular purpose That is how we classify software products in two ways As I said, software engineering is related to software production, development and testing There are two phrases we use for this Discipline with respect to discipline and software production Discipline is all depending upon the engineering discipline That is, how do we select theories, methods and tools How do we discover a solution from a problem These are the things that are said in engineering discipline Aspects of software production All the technical processes that is behind the software development These are the two phrases we use for software engineering
