The advancement of technology has opened the so-called post-PC age, and the necessary functions are applied and integrated into an “embedded system” to meet the needs of special purpose, low cost and integrated service. Digital cameras, cell phones and PDAs are all applications of embedded system. Therefore, based on the embedded system and the employment of 802.11b wireless networks, a management system for business use is developed. Besides the new functions developed from the computerized operating management and integrated database application, different user interface web pages are provided for different users via web pages (such as the waiters, clerks and managers of a restaurant). Moreover, the operation and management of shops will be more convenient and efficient with the cooperation of utilizing the advantages of wireless networks. The embedded system with small volume and low cost that is produced and integrated for specific functions, using Linux OS with open source as the basic software structure of system, has further been more diversified and convenient in practice. Thus, the popularity of embedded systems will become an irresistible new trend, and the technology of developing embedded Linux systems will become the advantages for competition as well. So we not only need to thoroughly understand the method and process of developing embedded Linux systems and produce the convenient management system for businesses, but also need to utilize the debug work for program development so as to shorten the developing period of products and enhance the efficiency.CHAPTER 1 INTRODUCTION 1 1.1.
