1、dBASE、Fox系列由美国 Athton-Tate 公司推出的 dBASE Ⅱ、dBASEⅢ、dBAS Ⅲ Dlus 是国际上流行的微机数据库管理系统之一,被誉为“大众数据库”。由于其易于编程,易于实现,开发费用低,在我国得到广泛的应用。它适合编写小型管理软件,如图书管理、人事档案管理、工资管理、学籍管理等管理系统。九十年代以前所开发的微机管理系统,大多是用 dBASE 实现的。1987年美国 Fox Software 公司推出了新颖关系数据库管理系统 FoxBASE plus,它与 dBASEⅢ、dBASEⅢ plus 完全兼容,但速度快五——六倍,它增加的命令、函数和数组功能为编程带来更大方便,因而取代了dBASE 系列,象用友、安易、金蜘蛛等财务管理软件都是用 Fox BASE 开发的。Microsoft 公司的 Foxpro 是与 dBASE、FoxBASE 兼容的编译型的数据库管理软件,目前在我国拥有大量用户。与 dBASE、FoxBASE 不同,Foxpro 引入了面向对象的
1. dBASE, Fox series launched by the United States Athton-Tate dBASE II, dBASEIII, dBAS III Dlus is one of the most popular microcomputer database management systems in the world, known as the “mass database.” Because of its easy programming, easy implementation, low development cost, it has been widely used in our country. It is suitable for writing small-scale management software, such as management system such as book management, personnel file management, salary management, and student status management. Most computer management systems developed before the 1990s were implemented using dBASE. In 1987, Fox Software of the United States introduced FoxBASE plus, a novel relational database management system, which is fully compatible with dBASEIII and dBASEIII plus, but is five to six times faster. Its increased command, function, and array capabilities make programming easier. Therefore, it replaced the dBASE series, and financial management software such as UF, Anyi, and Golden Spider were all developed with Fox BASE. Microsoft’s Foxpro is a compiled database management software compatible with dBASE and FoxBASE, and currently has a large number of users in China. Unlike dBASE, FoxBASE, Foxpro introduces object-oriented
