1. INTRODUCTION Developing computer software and information systems is a procedure that has been usually worked on by various methodologies of development. Software development methodology is defined as the structure of planning, managing and controlling the process of building up an information system. Officially, the methodology of software development is called Software Development Life Cycle (SDLC), which is used mainly in various engineering and industrial work areas like software engineering
studies and their pros. & cons. At the end of this chapter I describe the summary of this chapter. Next chapter is Methodology. In this I explain my solution method of my web application. I draw the different diagrams i:e Flow charts, Data Flow Diagrams, Entity Relationship Diagrams, different Processes and Use case Diagrams etc. In this chapter I also explain my implementation and testing tools through which I will design my application. For example I will HTML and PHP as programming languages and
1. Discuss the compaction process. What do you think is the negative side of this process? When and how often should it be done? Discuss the various alternatives and their pros and cons. Data compaction is the reduction of the number of data elements, bandwidth, cost, and time for the generation, transmission, and storage of data without loss of information by eliminating unnecessary redundancy, removing irrelevancy, or using special coding. It is a method to overcome the external fragmentation
biometrics for oversight applications. Face perception is necessity in biometrics, often as a part of facial recognition system. It is also used in video surveillance and human electronic computer interface. Some novel digital cameras custom face detection for auto focus. Face detection is an electronic computer technology that limits the locations and sizes of earthborn face in arbitrary conception. It detects only facial features and ignores the background. Face detection is a novel approach through
