说明：  在软件业，AOP为Aspect Oriented Programming的缩写，意为：面向切面编程，通过预编译方式和运行期动态代理实现程序功能的统一维护的一种技术。AOP是OOP的延续，是软件开发中的一个热点，也是Spring框架中的一个重要内容，是函数式编程的一种衍生范型。利用AOP可以对业务逻辑的各个部分进行隔离，从而使得业务逻辑各部分之间的耦合度降低，提高程序的可重用性，同时提高了开发的效率(In the software industry, AOP is the abbreviation of Aspect Oriented Programming, which means: Face-Oriented Programming, a technology to achieve unified maintenance of program functions through pre-compiling and run-time dynamic proxy. AOP is the continuation of OOP, a hotspot in software development, an important content in Spring framework, and a derivative paradigm of functional programming. Using AOP can isolate all parts of business logic, which reduces the coupling between the parts of business logic, improves the reusability of programs, and improves the efficiency of development.)

说明：  信息科技经过 60 余年的发展，已经普及到社会生活的每一个角落。随着信息技术在国家治理、经济运行的方方面面的应用，大量的数据随之产生。而互联网技术的爆发式发展使得近年来产生的数据总量超过了人类以往产生的历史数据的总和，医疗行业的数据增长幅度尤为突出。 医疗大数据具有巨大的价值,尤其是在临床辅助诊疗和健康管理方面。医疗大数据已经上升到国家战略，同时也是全球学术界与产业界竞争的研究热点。如何利用这些医疗数据，挖掘数据的深层价值，是未来信息科技发展的趋势，也是医疗大数据技术产生的背景。(After more than 60 years of development, information technology has spread to every corner of social life. With the application of information technology in all aspects of national governance and economic operation, a large number of data are generated. The explosive development of Internet technology has made the total amount of data generated in recent years exceed the total amount of historical data generated by human beings in the past, and the growth rate of data in the medical industry is particularly prominent. Big medical data have great value, especially in clinical assistant diagnosis and health management. Big medical data has risen to national strategy, and it is also a research hotspot in the competition between global academia and industry. How to use these medical data to excavate the deep value of the data is the trend of the development of information technology in the future, and also the background of the emergence of medical big data technology.)
