In the paper,a Universal Table I/O Application Programming Interface (UTIOAPI)of Relational Database is presented for Windows NT. And frequently used I/O manipulations are given as a template by example. UTIOAPI is designed by using Object-Oriented techniques. As a brief, DBMS independent and high-level programming interface,UTIOAPI can be used to simplify database application programming greatly.%文章提出了一个在Windows NT环境下适用于关系数据库的通用表I/0应用程序接口UT0API,以例说明了UTI0API的应用模板。UTOAPI采用面向对象的设计方法和实现技术,为数据库应用提供了简洁的、独立于DBMS的高层程序设计接口,大大降低了编程的复杂性。
