  UNIT 3 Contents: Function-Oriented Software Design: Overview of SA/SD Methodology, Structured Analysis, Structured Design, Detailed Design, Design Review. User Interface Design: Characteristics of Good User Interface, Basic Concepts, Introduction to Function-Oriented Software Design: ●        Function-oriented design techniques were proposed nearly four decades ago. ●        still very popular and are currently being used in many software development organizations. These techniques, to start with, view a system as a black-box that provides a set of services to the users of the software. ●        These services are also known as the high-level functions supported by the software. During the design process, these high-level functions are successively decomposed into more detailed functions ●        The term top-down decomposition i s often used t...

  UNIT-II SOFTWARE PROJECT MANAGEMENT Software Project Management (SPM) is a proper way of planning and leading software projects. It is a part of project management in which software projects are planned, implemented, monitored, and controlled. This article focuses on discussing  Software Project Management (SPM) . Need for Software Project Management Software is a non-physical product.  Software development  is a new stream in business and there is very little experience in building software products. Most of the software products are made to fit clients’ requirements. The most important is that basic technology changes and advances so frequently and rapidly that the experience of one product may not be applied to the other one. Such types of business and environmental constraints increase  risk in software development  hence it is essential to manage software projects efficiently. It is necessary for an organization to deliver quality products,...

  UNIT-3   Software Design Process – Software Engineering   The design phase of software development deals with transforming the customer requirements as described in the SRS documents into a form implementable using a programming language. The software design process can be divided into the following three levels or phases of design: ·        Interface Design ·        Architectural Design ·        Detailed Design Elements of a System Architecture:  This is the conceptual model that defines the structure, behavior, and views of a system. We can use flowcharts to represent and illustrate the architecture. Modules:  These are components that handle one specific task in a system. A combination of the modules makes up the system. Components:  This provides a particular function or group of related functions. They are made up of modules. Interfaces:...
