3.1. Pipes and Filters In a pipe and filter style each component has a set of inputs and a set of outputs. A component reads streams of data on its inputs and produces streams of data on its outputs‚ delivering a complete instance of the result in a standard order. This is usually accomplished by applying a local transformation to the input streams and computing incrementally so output begins before input is consumed. Hence components are termed “filters”. The connectors of this style serve

Chapter 1 – Software and Software Engineering Overview Software is designed and built by software engineers. Software is used by virtually everyone in society. Software is pervasive in our commerce‚ our culture‚ and our everyday lives. Software engineers have a moral obligation to build reliable software that does no harm to other people. Software engineers view computer software‚ as being made up of the programs‚ documents‚ and data required to design and build the system. Software users are

Software Piracy: A Worldwide Problem Software piracy is defined as the illegal copying of software for commercial or personal gain. Software companies have tried many methods to prevent piracy‚ with varying degrees of success. Several agencies like the Software Publishers Association and the Business Software Alliance have been formed to combat both worldwide and domestic piracy. Software piracy is an unresolved‚ worldwide problem‚ costing millions of dollars in lost revenue. Software companies

probabilistic approach to finding failure-causing inputs based on Bayesian estimation. According to our probabilistic insights of software testing‚ the test case generation algorithms are developed by Markov chain Mote Carlo (MCMC) methods. Dissimilar to existing random testing schemes such as adaptive random testing‚ our approach can also utilize the prior knowledge on software testing. In experiments‚ we compare effectiveness of our MCMC-based random testing with both ordinary random testing and adaptive

traditional software metrics which could be applied to object–oriented programming and a set of object–oriented metrics (i.e. those designed specifically for object–oriented programming). Given the central role that software development plays in the delivery and application of information technology‚ managers are increasingly focusing on process improvement in the software development area. This demand has spurred the provision of a number of new and/or improved approaches to software development
