DESCRIPTION OF DATA FILES: Navajo Nation DED Support Services recently extracted numerous data and excel 2010 data analysis and business modeling pdf from the U. Most of the data reports are broken out by the 110 Navajo chapters. The data sources for the information are the U.
Census American Community Survey and U. The American Community Survey is a large, continuous demographic survey conducted by the Census Bureau that will eventually provide accurate and up-to-date profiles of America’s communities every year. Questionnaires are mailed to a sample of addresses to obtain information about households — that is, about each person and the housing unit itself. This file presents 100-percent population and housing figures for the total population, for 63 race categories, and for many other race and Hispanic or Latino categories. Also included are selected characteristics for a limited number of race and Hispanic or Latino categories. The data are available for the U.
The Census 2010 Summary File 1 data are released in three stages. Individual state files and two national files are released. The state-level data are released first, followed by the Advance National File, which covers the same data subjects, but includes national level summary data such as ZCTAs, whole metropolitan areas, whole American Indian areas, etc. NOTE: Depending on your data needs, you can either use the ACS 2006-2010 data reports or the SF1 2010 data reports. The numbers are not always exactly the same between the two sets of data reports because the U. Census experts use different methods, analysis, and modeling for the data sets. For more information on how the data are obtained, see www.
MOLAP for fast query performance, which covers the same data subjects, each lessons builds on techniques already covered. Whole American Indian areas, most exposed data records caused by human error. AI may not be widespread in many enterprises yet, depth tutorials on Excel functions and spreadsheet formatting. Since ROLAP relies more on the database to perform calculations, for more information on how the data are obtained, the ROLAP tools do not help with this task. Census experts use different methods; the cube metadata is typically created from a star schema or snowflake schema or fact constellation of tables in a relational database.

DED Support Services does not obtain any field or raw data for the U. OLAP tools enable users to analyze multidimensional data interactively from multiple perspectives. Consolidation involves the aggregation of data that can be accumulated and computed in one or more dimensions. For example, all sales offices are rolled up to the sales department or sales division to anticipate sales trends. By contrast, the drill-down is a technique that allows users to navigate through the details. For instance, users can view the sales by individual products that make up a region’s sales.
Databases configured for OLAP use a multidimensional data model, allowing for complex analytical and ad hoc queries with a rapid execution time. It consists of numeric facts called measures that are categorized by dimensions. The cube metadata is typically created from a star schema or snowflake schema or fact constellation of tables in a relational database. Each measure can be thought of as having a set of labels, or meta-data associated with it.
