This quotation is from a workshop 来自培训班的一则引言

The history of database system research is one of exceptional productivity and startling economic impact.

数据库系统研究的历史是重要成果之一，而且正在发挥着令人振惊的经济影响。

Barely 20 years olds as a basic science research field, database research has fueled an information services industry estimated at $10 billion per year in the U.S. alone. 

将近20年，作为一门基础学科研究领域，数据库研究已经推动了信息服务工业的成立，仅仅在美国每年以100万递增。

Achievements in database research underpin fundamental advances in communications systems, transportation and logistics, financial management, knowledge-based systems, accessibility to literature, and a host of other civilian and defense application.

在数据库研究的成果，支撑了信息系统的根本性进步，交通、运输、财经管理、基础知识体系，无障碍文学，和其它民用和国防应用的进步。

 They also server as the foundation for considerable progress in the basic science fields ranging from computing to biology.

他们也被用作为一些程序的基础在科学里，从算机以生物到生物学。

 

This quotation is from a workshop on database systems at the beginning of the 1990s and expanded upon in a substance workshop in 1996, and it provides substantial motivation for the study of the subject of this book: the database system. 

这段引言来自数据库系统培训班在20世纪90年代初期，并在1996年发展为重要的培训班，它提供了重要的动力：数据库系统。

substance /s'ʌbstəns/ n. substance is the quality of being important or significant.   

 

Since these workshops, the importance of the database system has, if anything, increased, with significant developments in hardware capability, hardware capacity, and communications, and grid computing.

由于这些培训班，数据库系统的重要性，无论如何，已经增加，在硬件性能方面带有重要的开发，硬件资源、和通讯、和计算机计算。

capability /k'eipəb'iliti/ (capabilities) 1. [N-var] with supp, oft adj n, N to-inf   If you have the capability or the capabilities to do something, you have the ability or the qualities that are necessary to do it.

People experience differences in physical and mental capability depending on the time of day...

capacity /kəp'æsiti/ n. 1. the capacity of something such as a factory, industry, or fegion is the quantity of things that it can produce or deliver with the equipment or resources that are available.

 The database systems is arguably the most important development in the field of software engineering, and the database is now the underlying framework of the information system, fundamentally changing  the way that many organization operate.

数据库系统毫无疑问是软件工程领域中最重要的发展， 现在数据库也是信息系统的底层框架，从根本上改变组织性操作。

Database technology has been an exciting area to work in, and since its emergence, has been the catalyst for many important developments in software engineering.

 catalyst  //  1.[n-count ] oft N for n  You can describe a person or thing that causes  a change or event  to happen as a catalyst.

2. In chemstry, a catalyst is a substance that cause a chemical to take place more quickly.
