摘要
为了加强城市居民最低生活保障(以下简称低保)问题的基础信息的科学管理,为政府部门提供对低保问题的决策支持,将数据集市理论运用于低保基础信息的决策管理。提出了低保基础信息数据集市的数据模型——雪花模型,并对数据模型中的事实表、维度表、大维度、粒度、聚集事实表等相关的技术问题进行了细致的探讨,对研究并建立低保基础信息数据集市具有参考价值和实际意义。
In order to strengthen the scientific management of basic information of the subsistence allowances for urban residents, and provide government departments with decision-making support of subsistence allowances, applied data market theory into the decision-making management based on information of subsistence allowances. Presented the data model of information data market of subsistence allowances： snowflakes model, and made a detailed study of many related technical issues in the data model, such as the facts table, the dimension table, giant dimension, granularity, gathering facts table, etc. So it is of a reference value and practical significance to researching and establishing information data market of subsistence allowances.
