ND Spring Powerschool User Group Meeting Using Excel in Data Mining ND Spring PowerSchool User Group Meeting Using Excel in Data Mining Your PowerSchool David Sherwin Bismarck School District Some information taken from the PowerSchool Import and Export User Guide PowerSchool Data Mining PowerSchool can be used to export large amounts of data from various tables in DDE. With relational codes, data can be exported from various tables such as the Students, Attendance, Current Course and others and be opened with Excel to be analyzed using PivotTables and other functions of Excel. A PivotTable report is an interactive table that can be used to quickly summarize large amounts of data. You can rotate its rows and columns to see different summaries of the source data, filter the data by displaying different pages, or display the details for areas of interest. What is (DDE) - Direct Database Export PowerSchool data is stored as records in various tables of a relational database. Each table contains an unlimited number of records with specific fields for each table. When you use (DDE), you directly access records from one of the many tables in the relational database. On the Direct Database Export (DDE) page you can search and match data in all of the internal tables on your PowerSchool server. Then create an export file or report that contains records from the tables and relational records. When you export data from (DDE), the system creates an independent export file that you can open or update using any application you want. The most common application used is a spreadsheet, to view or organize the records. Note: Depending on your security settings, you may not be able to perform all functions.

This makes Pivot Tables interactive in that once the table is complete you can very easily see what effect moving (or pivoting) your data has on your information. This will become clear once you give Pivot Tables a go. No matter how experienced you get at Pivot Tables there will always be an element of trial-and- error involved in producing the desired results! What this means is you will find yourself pivoting your table a lot! Why use PivotTables You would use a Pivot Table to produce meaningful information from a table of information. Imagine you have a table of data that contains student names, grade levels, courses, grades, GPA, teachers, period and attendance etc… With a Pivot Table you could very easily and quickly find out: • How many students are enrolled in various courses • The letter grade distribution by grade level • A count of students absences by category • See the students’ performance by course of a particular ethnicity • Locate errors in current data In fact the list can go on and on! What is the Advantage Perhaps the biggest advantage to using Pivot Tables is the fact that you can generate and extract meaningful information from a large table of information within a matter of minutes. In a lot of cases you could get the same results from a table of data by using Excels built in functions, but this would take more time. On top of this, if you wanted some new information you can simply drag-and-drop (pivot). You can also opt to have your information update each time you open the Workbook and/or by clicking refresh. 3 ND Spring PowerSchool Users Group Meeting Mining Your Data from PowerSchool How to Select Records for Exporting Select all records in a selected table, or search for specific records in a table. The following table explains the data to enter search information in the fields: Field Description Current Table Choose the table from which you want to export records from the pop-up menu. Current Records in Selection: To indicate the records to use in the export, do one of the all [x] records in this table following: • Click "Select all [number of] records in this table" to use all records. or limit the export by searching • Or limit the export by identifying search criteria in the Search Students fields on the DDE export page by continuing to the next step.

  • (BI) Using MS Excel Powerpivot
    2018 ASCUE Proceedings Developing an Introductory Class in Business Intelligence (BI) Using MS Excel Powerpivot Dr. Sam Hijazi Trevor Curtis Texas Lutheran University 1000 West Court Street Seguin, Texas 78130 [email protected] Abstract Asking questions about your data is a constant application of all business organizations. To facilitate decision making and improve business performance, a business intelligence application must be an in- tegral part of everyday management practices. Microsoft Excel added PowerPivot and PowerPivot offi- cially to facilitate this process with minimum cost, knowing that many business people are already fa- miliar with MS Excel. This paper will design an introductory class to business intelligence (BI) using Excel PowerPivot. If an educator decides to adopt this paper for teaching an introductory BI class, students should have previ- ous familiarity with Excel’s functions and formulas. This paper will focus on four significant phases all students need to complete in a three-credit class. First, students must understand the process of achiev- ing small database normalization and how to bring these tables to Excel or develop them directly within Excel PowerPivot. This paper will walk the reader through these steps to complete the task of creating the normalization, along with the linking and bringing the tables and their relationships to excel. Sec- ond, an introduction to Data Analysis Expression (DAX) will be discussed. Introduction It is not that difficult to realize the increase in the amount of data we have generated in the recent memory of our existence as a human race. To realize that more than 90% of the world’s data has been amassed in the past two years alone (Vidas M.) is to realize the need to manage such volume.

  • Fast Foreign-Key Detection in Microsoft SQL
    Fast Foreign-Key Detection in Microsoft SQL Server PowerPivot for Excel Zhimin Chen Vivek Narasayya Surajit Chaudhuri Microsoft Research Microsoft Research Microsoft Research [email protected] [email protected] [email protected] ABSTRACT stored in a relational database, which they can import into Excel. Microsoft SQL Server PowerPivot for Excel, or PowerPivot for Other sources of data are text files, web data feeds or in general any short, is an in-memory business intelligence (BI) engine that tabular data range imported into Excel. enables Excel users to interactively create pivot tables over large data sets imported from sources such as relational databases, text files and web data feeds. Unlike traditional pivot tables in Excel that are defined on a single table, PowerPivot allows analysis over multiple tables connected via foreign-key joins. In many cases however, these foreign-key relationships are not known a priori, and information workers are often not be sophisticated enough to define these relationships. Therefore, the ability to automatically discover foreign-key relationships in PowerPivot is valuable, if not essential. The key challenge is to perform this detection interactively and with high precision even when data sets scale to hundreds of millions of rows and the schema contains tens of tables and hundreds of columns. In this paper, we describe techniques for fast foreign-key detection in PowerPivot and experimentally evaluate its accuracy, performance and scale on both synthetic benchmarks and real-world data sets. These techniques have been incorporated into PowerPivot for Excel. Figure 1. Example of pivot table in Excel. It enables multi- dimensional analysis over a single table.

The goal is to create a business intelligence system that, in a simple, quick but also versatile way, allows the access to updated, aggregated, real and/or projected information, regarding bank account balances. The established system extracts and processes the operational database information which supports cash management information by using Integration Services and Analysis Services tools from Microsoft SQL Server. The end-user interface is a pivot table, properly arranged to explore the information available by the produced cube. The results have shown that the adoption of online analytical processing cubes offers better performance and provides a more automated and robust process to analyze current and provisional aggregated financial data balances compared to the current process based on static reports built from transactional databases.

  • Pivot Tables
    PIVOT TABLES In data processing, a pivot table is a data summarization tool found in data visualization programs such as spreadsheets or business intelligence software. Among other functions, a pivot-table can automatically sort, count total or give the average of the data stored in one table or spreadsheet. It displays the results in a second table (called a "pivot table") showing the summarized data. Pivot tables can be seen as a simplification of the more complete and complex. Pivot tables are my best friend. GIS ANAYSIS NEEDED: The Panther Focus Area represents lands that are crucial for the Florida panther’s survival.

  • Appendix D: How to Use a Data Spreadsheet: Excel
    Appendix D How to Use a Data Spreadsheet: Excel ne does not necessarily have special statistical software to perform statistical analyses. Microsoft Office Excel can be used to run statistical procedures. Although in some respects Excel is not as preferable for data analyses as IBM SPSS, it is very user- friendly with simpler statistical procedures. This appendix describes how to use Excel to execute basic statistical calculations. Data from the 2004 version of the General Social Survey (GSS) is used for examples. OThis Appendix is based on Excel 2007 version, which differs in certain aspects from Excel’s previous versions. The most notable change that affects the exercises presented in this appendix concerns the pivot table feature. 22BASIC PROCEDURES Starting Excel: To start Excel using Windows, click on the Start button at the bottom left corner of the screen. Under Programs locate and click the Microsoft Excel icon. The layout of the Excel program has changed substantially for the Microsoft Office 2007 edition compared to its predeces- sors. Commands are now grouped in ribbons that are accessed by clicking on a specific tab. Thus, the Home tab grants access to a ribbon of several command groups: Clipboard, Font, Alignment, Number, Styles, Cells, and Editing. Once the program is started you will see a Worksheet Area that consists of cells forming columns and rows. Rows are identi- fied by numbers, and columns are identified by letters. Consequently, each cell has its own unique address—a combination of letters and numbers. For example, cell C6 is in column C, row6. The dark rim around a cell means that the cell is highlighted or active.
