问题 WebSQL is a SQL-like(36)language for extracting information from the web. Its capabilities for performing navigation of web(37)make it a useful tool for automating several web-related tasks that require the systematic processing of either all the links in a page, all the pages that can be reached from a given URL through paths that match a pattern, or a combination of both. WebSQL also provides transparent access to index servers that can be queried via the Common Gateway Interface.
选项 A、query
B、transaction
C、communication
D、programming
答案A
解析 WebSQL是一种类似于SQL的查询语言，用于从Web中提取信息。它能够在Web超文本中巡航，这使得它成为自动操作一个页面中有关链接的有用工具，或是作为搜索从一个给定的URL可以到达的、所有匹配某种模式的页面的有用工具。WebSQL也提供透明地访问索引服务器的手段，这种服务器可以通过公共网关接口进行查询。
