| 1. | It is a implemention of deductive query algorithms
是该演绎数据库推理机制查询算法的一种实现。 |
| 2. | To make deductive database in data query get improvement in function and efficiency , we must build a perfect . science . strict system structure fragment for inferring mechnism running
人们要想使演绎数据库在数据库查询达到功效上的大大提高，就必须构造一种完善、科学、严谨的系统结构框架。 |
| 3. | In field of deductive database , magic transformation is an evaluation strategy that combines top - down with bottom - up . it restricts the computation of logic program to tuples that are related to the query
在演绎数据库领域中，魔集转换是一种自顶向下和自底向上相结合的计算策略，它使逻辑程序的计算始终限制在与查询相关的数据中。 |
| 4. | Deductive database is introduction to knowledge and inferring mechnism in artificial intelligece in traditional database . studying it needs very strict theory model as background . relation model and datalog model can describe world
演绎数据库是人工智能中的知识及其推理机制在传统数据库中的引入，对它的研究需要有非常严谨的理论模型为背景，它用关系模型(描述事实)和datalog模型(描述规则)来描述世界，演绎数据库中主要采用一阶谓词逻辑表示。 |
| 5. | Deductive database makes good use of predicate logic . because it has strict , systemic , maths theory logic theory base and stronger inferring mechnism . on the basis of traditional database . it introduces design idea , structure , implemention and system model and so on
本论文在传统数据库的基础上借鉴了人工智能中知识表示、推理机制，集思广益，博采众长，介绍了演绎数据库系统设计思想，系统的结构，系统推理机制的实现以及系统模型的建模理论依据等。 |
| 6. | As deductive database knowledge reasoning differs from artificial intelligence , it borrows some reasoning ideas from artificial intelligence . so inferring realization in artificial intelligence did n ' t entirely put into deductive database . the researchers have long been studying and exploring to find effective and general algorithms
由于演绎数据库知识推理面向对象与人工智能不同，它只借鉴了人工智能中的一些推理思想，所以人工智能的推理实现并不能完全引入演绎数据库中，经国内外研究人员长期不懈地研究、探讨，寻找高效通用科学的方法。 |
| 7. | Finally , makes good use of distributed database paralleling processing advantage and major recursive forms are single linear recursive forms and single recursive can turn into a union form n chain recursive . it introduces a / v _ chain recursive query algorithms with paralleling processing to show ddb " s insurance
最后，借鉴了分布式数据库并行处理的优势和多数递归形式是单线性递归形式的共识以及单线递归都可以转化为一种共同形式? n链递归，介绍了演绎数据库系统递归查询算法?并行处理的n链递归查询算法，以示ddb的可靠性。 |
