This document describes the creation of an SSAS cube and dimensions using data from a construction company database to enable analysis through MDX queries and key performance indicators (KPIs). Sections include an overview, description of the cube and dimension creation, MDX queries grouped by job, overhead, materials and labor summaries, and 5 KPIs measuring metrics like open receivables, job growth, overhead percentage, and profit change. Appendices provide screenshots of the data model, queries and KPIs.

Overview

This project creates the Cubes and Dimensions necessary to generate MDX Queries and Key Performance Indicators (KPIs) for a simulated Construction company. The focus of the data for this project is on data for labor, materials, overhead, and summarized job information. The data was loaded from a zipped database and a cube and its associated dimension and hierarchies. The Data Source and Data Source Views were defined. Once this was done, the cube was created and then dimensions were created in order to organize the data in such a way as to enable the MDX queries and KPIs to perform their functions efficiently.The net result was a collection of MDX queries and KPIs showing critical business information in a way that it can be quickly analyzed.

In creating the cube a data base was supplied containing all of the necessary data to carry this project forward. The database name was SSASStudentProject. Setting up the Data Source Connection to the Database TC

The connection was set to the SSASStudentProject database located in the folder: C:etFocusBIProjectstudentVersionSASStudentProjectSASStudentProjectin A Data Source View was set up to design the chart showing the data relationships and establishing the Fact Tables (Measures) and the Dimensions. This chart can be viewed in Appendix A. Build the cube TC

once the database connect had been established and the Data Source View created, the Cube, AllWorks Cube was created. As this was accomplished, a basic chart was created showing the relationships of the data within the cube. The wizard was used to create the cube and then the individual elements were adjusted as necessary for producing the desired queries and KPIs. This Cube Design chart can be seen in Appendix B.

The MDX queries are grouped in to several categories. They will be presented in those groupings. An example of the display of each can be found in the appendixes as indicated in the description for each query. Job Summaries TC

JobSummary01.mdxRetrieve total labor costs by Client JobSummary02.mdxRetrieves total labor costs by Client, and filters out any NULL values JobSummary03.mdxRetrieve total labor costs by County JobSummary04.mdxRetrieve total labor costs by Division JobSummary05.mdxRetrieve total labor costs by Client Account grouping JobSummary06.mdxBy client, retrieve total labor cost, total material cost, and total overhead. JobSummary07.mdxDo the same (retrieve 3 measures) and add a 4th measure, a calculated measure, that adds all three costs. JobSummary08.mdxRetrieve and calculate the total costs, the total profit, and total profit %, for each individual job. The three re calculated as follows: Total costs=total labor cost + total material cost+ total overhead cost Total profit=labor profit+ material profit+ additional labor overhead profit Total profit %= (total profit / (total cost + total profit))*100 JobSummary09.mdxBy client, retrieves and calculate the total costs, the total profit, and total profit %, for each individual job. The three re calculated as follows: Total costs=total labor cost + total material cost+ total overhead cost Total profit=labor profit+ material profit+ additional labor overhead profit Total profit %= (total profit / (total cost + total profit) )*100 JobSummary10.mdxBy client, displays a count of Jobs. JobSummary11.mdxRetrieve all Clients with a Total Labor cost to date greater than 5,000, and the word 'INC' appears in the client name JobSummary12.mdxList the jobs that make up the top 30% of total invoice amount.

JobOverHead01.mdxShows Overhead by Overhead Category for Q3 and Q4 2005 (hint, use the FY Qtr as a dimension). JobOverHead02.mdxShows Overhead by Overhead Category for Q3 and Q4 2005, and also show the % of change between the two. JobOverHead03.mdxShows Overhead by Overhead Category for all of 2005, order by Overhead Dollar amount descending. Materials Summaries TC

The result set should have 1 column for the purchase amounts for Fuel, Materials, and petty Cash. JobOverMaterials02.mdxShows Material purchase amounts for 2005, broken out by Material Purchase type and client. JobOverMaterials03.mdxShows a list of total client material purchases for 2005, in descending purchase amount order. The result set should show at the top which client required the most materials. JobOverMaterials04.mdxShows jobs in order of purchase amount and then show the breakdown in each job of material type (for instance, Job A, total purchase amount, amount for fuel, amount for materials, amount for petty cash, etc.). The general order should be by total purchase amount, so that the top of the result set shows the jobs that required the highest purchase amounts. Labor Summaries TC

JobOverLabor01.mdxLists Hours Worked and Total Labor for each employee for 2005, along with the labor rate (Total labor / Hours worked). JobOverLabor02.mdxLists Hours Worked and Total Labor for each employee for 2005, along with the labor rate (Total labor / Hours worked). The listing will sort the employees by labor rate descending, to see the employees with the highest labor rate at the top. JobOverLabor03.mdxFor 2005, show Total Hours worked, total labor dollars, and total labor rate for contractors (employee flag is false) and employees (employee flag is true). JobOverLabor04.mdxFor 2005, this shows the job and the top three employees who worked the most hours. Show the jobs in job order, and within the job show the employees in hours worked order. JobOverLabor04.mdxShows All employees for 2005 Q4, and four periods ago, for total hours worked in the Quarter. Key Performance Indicators ( KPIs) TC

Five KPIs were created using the Allworks Cube and its associated dimensions. They are briefly described below. Where possible, when a division provides that possibility for the potential of a “divde by zero” condition, checks are made and steps taken to avoid output errors. If the denominator turn out to be a zero, the out is converted to 100%. % Open Receivables TC
