| 摘要: |
| 实时交互式分析针对多目标和多角度的分析任务，通过多轮次的用户-数据库交互过程，逐步明确分析任务与分析目标，全方位地了解相关领域信息，最终得到科学的、全面的分析结果.相比传统数据库“提交查询-返回结果”的单轮次交互查询方式，实时交互式分析更强调交互的实时性与查询结果的时效性.对实时交互式分析的研究已成为近几年研究的热点.针对当前实时交互式分析面临的若干关键问题，对现有的实时交互式分析研究的理论基础、数据模型与系统构架进行了综述. |

| Abstract: |
| Real-time interactive analysis focuses on multi-object and multi-perspective analysis tasks. By employing a multiple userdatabase interaction process, interactive analysis is able to provide a more comprehensive understanding of the analytic task. Comparing to traditional database where queries are issued and answered in a single interaction, interactive analysis emphasizes on the responses time of the query and timeliness of the results. Real-time interactive analysis has been extensively studied in recently years. In this survey, comprehensive review is provided on the theoretical foundation, data models, and systems of the real-time interactive analysis. |
