Internet-based Dissemination of NLTCS Data

描述(由申请人提供)：国家长期护理调查(NLTCS)收集关于65岁及以上老年人长期护理(LTC)状况的纵向数据。杜克大学人口研究中心(CDS)分发这些数据的公共使用文件(PUF)和分析文件，旨在估计基于家庭和社区的LTC保险单的索赔成本。这些文件和NLTCS的研究成果没有得到广泛的分发，非技术用户也不容易获取。此外，准备分析文件的分析步骤非常耗时，这会延迟数据的分发。 知情决策公司(ID)正在开发一种软件，用于用任何关系数据库中的数据生成动态超立方体(DH)，并将它们发布在互联网上。非技术用户将能够进行交互的简单分析，并从一个数据挖掘中生成多个表格。国土安全部还将用于优化分析文件的数据清理和分析步骤。杜克大学CDS将负责为ID提供NLTCS上的专家输入，并提供调查与第一阶段正在开发和应用的软件程序的接口。最终产品将足够通用，可应用于几乎任何数据库。

DESCRIPTION (provided by applicant): The National Long Term Care Survey (NLTCS) collects longitudinal data on persons aged 65 and older about their Long-Term Care (LTC) status. The Center for Demographic Studies (CDS) at Duke University distributes Public Use Files (PUF) and Analytical Files of these data, designed for estimating claim costs for Home and Community Based LTC insurance policies. These files and the research results from the NLTCS do not receive wide distribution, and are not easily accessible to non-technical users. Also the analysis steps for preparing Analytical Files are very time consuming, and this delays the distribution of data. Informed Decisions, Inc., (ID) is developing software for generating Dynamic Hypercubes (DH) with data from any relational database, and post them on the Internet. Non-technical users will be able to do interactively simple analyses and generate many tables from one DH. The DHs will also be applied to optimize data cleaning and analyses steps for the Analytical Files. Duke University CDS will be responsible for providing ID with expert input on the NLTCS and the interface of the survey with the software procedures being developed and applied in Phase I. The final product will be general enough for application to practically any database.
