We all structure information in our brains: without structure, we would not be able to deal with the huge quantities of highly heterogenous information we process. However, each of us structures this information slightly differently, often leading to misunderstandings or requiring additional rounds of dialog to clarify. Database schema are also designed by humans. The structure imposed on the information by the schema reflects the human designers' perspective on the world, even if mediated through formal design techniques or computer software. Therefore, the structured data querying task can be viewed as having a schema mapping problem at its core: mapping between the "schema" the human has in her brain and the schema used to organize the database.

技术视角

我们都在大脑中构建信息:没有结构,我们将无法处理我们处理的大量高度异构的信息。然而,我们每个人对这些信息的结构略有不同,经常导致误解或需要额外的对话来澄清。数据库模式也是由人类设计的。图式强加于信息的结构反映了人类设计师对世界的看法,即使通过正式的设计技术或计算机软件进行调解也是如此。因此,结构化数据查询任务可以被视为其核心存在模式映射问题:人类大脑中的“模式”与用于组织数据库的模式之间的映射。
