摘要

演示的高级决策查询语言DQL结合了数学规划的决策优化能力和传统数据库查询语言的数据操作能力。DQL在两个方面对应用程序开发人员有利。首先，它避免了数学编程和数据访问之间的概念阻抗不匹配，并使没有运筹学经验的数据库程序员很容易访问决策优化功能。其次，与松散耦合的系统相比，紧密集成为更有效的评估提供了独特的机会。本演示使用一个紧急响应场景来说明该语言及其实现的强大功能。

A decisions query language (DQL): high-level abstraction for mathematical programming over databases

The demonstrated, high-level decisions query language DQL combines the decision optimization capability of mathematical programming and the data manipulation capability of traditional database query languages. DQL benefits application developers in two aspects. First, it avoids a conceptual impedance mismatch between mathematical programming and data access and makes decision optimization functionality readily accessible to database programmers with no prior experience in operations research. Second, a tight integration provides unique opportunities for more efficient evaluation as compared to a loosely coupled system. This demonstration uses an emergency response scenario to illustrate the power of the language and its implementation.
