External entities are objects outside the system‚ with which the system communicates. External entities are sources and destinations of the system’s inputs and outputs. 1.b) ENTITY RELATIONSHIP DIAGRAM Entity–relationship model (ER model) in software engineering is an abstract way to describe a database. This article refers to the techniques proposed in Peter Chen’s 1976 paper.An ER model is an abstract way to describe a database. There are three basic elements in ER models: Entities are

Software Testing Carnegie Mellon University 18-849b Dependable Embedded Systems Spring 1999 Authors: Jiantao Pan mailto:%20jpan@cmu.edu Abstract: Software testing is any activity aimed at evaluating an attribute or capability of a program or system and determining that it meets its required results. [Hetzel88] Although crucial to software quality and widely deployed by programmers and testers‚ software testing still remains an art‚ due to limited understanding of the principles of software

SOFTWARE TESTING SOFTWARE TESTING Testing is the process of executing a program with the intent of finding errors. TESTING PRINCIPLES All tests should be traceable to customer requirements. Tests should be planned long before testing begins. The Pareto principle applies to software testing. Stated simply‚ the Pareto principle implies that 80 percent of all errors uncovered during testing will likely be traceable to 20 percent of all program components. TESTING PRINCIPLES Testing should begin

Evolution of Software The Early Years (50’s – 60’s) * This generation was characterized by Batch orientation‚ limited distribution‚ and customization of software. * In Batch Processing‚ the system handles an entire sequence of jobs together‚ often with little or no human intervention. * Also‚ as computers were not widely used at that time‚ only in scientific and military institutions‚ software could be highly customized since distribution was limited. Job mobility was low‚ and the
