XML XML? 전자적으로 데이터를 교환하기 위한 표준. Why XML? SGML은 선택 사항이 많고 복잡함. HTML은 미리 정의된 태그를 사용함. Copyright 2007 Seoul National University of Technology Dept. of Computer Science & Engineering and AhnSeungRye all right reserved.

What is Ajax? Asynchronous JavaScript And XML Web Server와 비(非)동기적으로 데이터를 교환하고 조작하기 위한 방법 장점 서버 처리를 기다리지 않고, 비(非)동기 요청이 가능하다. 수신하는 데이터 량을 줄일 수 있고, 클라이언트에게 처리를 위임할 수도 있다. 단점 Ajax를 쓸 수 없는 브라우저에 대한 문제가 있다. 페이지 이동 없는 통신으로 인한 보안상의 문제 지원하는 Charset이 한정되어 있다. 스크립트로 작성되므로 Debugging이 용이하지 않다. 요청을 남발하면 역으로 서버 부하가 늘 수 있음 Copyright 2007 Seoul National University of Technology Dept. of Computer Science & Engineering and AhnSeungRye all right reserved.
