Computer aided software engineering (CASE) is the implementation of computer facilitated tools and methods in software development. It is termed as waterfall because the model develops systematically from one phase to another in a downward fashion. Software is a general term for the various kinds of program s used to operate computer s and related devices. The process to gather the software requirements from client, analyze and document them is known as requirement engineering. Full stack engineers are very much in demand in today's software industry because they can work across the entire company architecture. By contrast, the more traditional models included a waterfall model, where each stage of development was done discreetly and separately from the others. Software is defined as collection of computer programs, procedures, rules and data. Software engineering was introduced to address the issues of low-quality software projects. E The two important software characteristics are: 1. A software engineer develops or designs new applications with the software needs of end-users in mind.

C Process Metrics:These are the measures of various characteristics of the software development process. F G To prevent incorrect operation of a software or system, debugging is used to find and resolve bugs or defects. By contrast, software developers are likely to be much closer to those core processes involved in the software development life cycle. A data dictionary is a file or a set of files that includes a database's metadata. Reinforcement Learning Vs. Software engineering has a great solution to decrease the complexity of any project. Software engineering is the application of science to consistently produce software based systems that are acceptable against the needed criteria (reliability, maintainability, security, safety, efficiency, usability) in a cost effective way. They are not constrained by the properties of materials, governed by physical laws, or by manufacturing processes. • The platform migration process, which is used if software is needed to be ported to another platform without any change in functionality. Scalability- If the software process were not based on scientific and engineering concepts, it would be easier to re-create new software than to scale an existing one. What does software engineering mean? B) coordinate a large number of developers. First of all the term "software engineer" has generally replaced the term "programmer". Software is a model of the real world. Software engineering treats the approach to developing software as a formal process much like that found in traditional engineering. Software is a set of instructions, data or programs used to operate computers and execute specific tasks. It, Systems design is the process of defining elements of a system like modules, architecture, components and their interfaces and data for a system based on the specified requirements.
