城镇低保基础信息数据集市的数据模型设计

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。

Data model design of town subsistence allowances basic information data market

In order to strengthen the scientific management of basic information of the subsistence allowances for urban resi-dents, and provide government departments with decision-making support of subsistence allowances, applied data market theo-ry into the decision-making management based on information of subsistence allowances. Presented the data model of informa-tion 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 allo-wances.
