System Design contains Logical Designing & Physical Designing. Logical designing describes the structure & characteristics or features, like output, input, files, database & procedures. The physical design which follows the logical design, actual software & a working system. There will be constraints like Hardware, Software, Cost, and Time & Interfaces, While Structured design is a data flow methodology. The graphical representation of data flow, communication & defining the modules & their relationship with each is known as Structure Chart. This method decomposes & modularizes the system so that the complexity & manageability will come down. Thus reducing the intuitive reasoning & promotes the maintainable provable systems. Barcode Reader is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port. Computers are fast becoming our way of life and one cannot imagine life without computers in today’s world. Go to a library or go to a bank, computers at all places. Since computers are used in every possible field today, it becomes an important issue to understand and build these computerized systems in an effective way. The goal is to work smarter, get real value from efforts, increase efficiency, and save time. Today, more organizations are turning on to computer based information system to help them deal to the problem that they encountered in the company. These impacts most of the levels in organization because of the large amount of data that is accumulated. And the manual way of maintaining a data is not enough to store a data or information. There will be unavailability for future use, since data might get misplaced
