基于时态的次协调数据库的研究

Research on Temporal Paraconsistent Database

  • 摘要: 基于时态的次协调数据库的数据模型是用来处理以时间为推移的数据库中不完全信息和矛盾信息.本文基于这样的数据模型,首先,提出三史制和超期数据转移算法及时间点抽取算法,这些算法可用于处理大量的过期数据,同时使用双向链表存储此类数据;其次,提出基于时态的次协调数据库查询语言(TPQL)实现此种数据库的相关查询与操作功能.

     

    Abstract: Temporal Paraconsistent database is introduced to manipulate incomplete and inconsistent information in database that vary over time.In this article, firstly, three historical segments, age transferring algorithm and time point selection algorithm are provided to solve the problem of overdue information, meanwhile, doubly linked list is used to store data;secondly, TPQL, as an extension of UcQL, is given for the sake of query and manipulation on this kind of data.
