A project has been developed to advance the capabilities of the National Center for Education Statistics (NCES) to support the dissemination of linked data from multiple surveys, multiple components within a survey, and multiple time points. An essential element of this study is the development of a software prototype system to facilitate NCES data customers' access to linked historical data (i.e., a data warehouse). Following an introduction, section 2 summarizes research in data warehousing. Section 3 documents the range of potential linkages using historical NCES survey data, describes recent linking projects, and explains the selection of data for the warehousing project. Section 4 addresses the objective of the data warehouse, explains metadata, and provides a description of the data model developed to represent multiple years of the Common Core of Data district level data set. Section 5 describes the steps and tools used in implementation of the model into a prototype warehouse, and section 6 contains conclusions based on this study. Section 7 contains selected references. Three appendixes contain supplemental information about the interviews, data imputation, and sample screens from the software. (Contains 5 tables, 3 figures, and 35 references.) (SLD)
