基于FPGA的DDS算法的实现，已经通过FPGA的后端仿真实现-FPGA-based algorithm cordic, has passed the back-end FPGA simulation

1、客户数据从Excel或Access中导入 2、数据量比较大，约200多万条记录 3、实现分地区查询 4、实现其他条件查询 （关键字） 5、实现分地区查询的用户权限限制，即特定用户只能查找特定地区的客户信息（显示）(1, the customer data from Excel or Access to import 2, larger than the data, about 10,000 more than 200 records of 3, to achieve sub-region query 4, the realization of other conditions query (keyword) 5, to achieve sub-region query user rights restrictions that particular user can only search a specific area of customer information (show))

Qt is a well-known cross-platform C++ visual development platform. Qt open source version provides the same functions as the commercial version. Qt 5 Development and Instance (2nd Edition) inherits the popular Qt 5 development and examples from the market.At the same time (Q1 5.4.0), QT application development is more systematic and more readable.This book is divided into two parts: The first part is the traditional Qt Widget programming. Each chapter introduces the Qt 5 application in a small example based on a brief introduction to the development environment.The development techniques of the program are generally introduced and explained through examples.
