  • Data Modeling 3 © Chris Bull 2009
  • This relational physical model was created for a mobile dispatching application for telecom Technicians 4 © Chris Bull 2009
  • This model is for a book sales data warehouse 5 © Chris Bull 2009
  • SQL Server TSQL Programming 6 © Chris Bull 2009
  • This query joins the Item and Reservation tables to produce a list of books where there are ten copies or less and more than 50 reservations. Sample Output SELECT ti.title_no , ti.title , rs.isbn , COUNT(*) FROM Title ti JOIN item itm ON ti.title_no = itm.title_no JOIN reservation rs ON rs.isbn = itm.isbn WHERE 11 > (SELECT count(cp.copy_no) FROM copy cp WHERE cp.isbn = itm.isbn) AND itm.isbn IN (SELECT DISTINCT rs1.isbn FROM reservation rs1 WHERE 50 < (SELECT COUNT(*) FROM Reservation rs2 WHERE rs1.isbn = rs2.isbn)) GROUP BY ti.title_no, ti.title, rs.isbn ORDER BY ti.title_no 7 © Chris Bull 2009
  • This script loads the Date Dimension of an Analysis Services staging database. This script could easily be converted into a Stored Procedure with Start and End date parameters. USE B4_TeamE_Staging go DECLARE @StartDate As Datetime, @EndDate As Datetime SET @StartDate = '1/1/2002' Sample Output SELECT @EndDate = CONVERT ( varchar(20) , MAX(CreationDate), 101 ) FROM Applicant PRINT 'Start Loop' WHILE @StartDate <= @EndDate BEGIN INSERT INTO dimDate (CreationDate ,Year ,WeekEnding ,MonthValue ,MonthDesc ,QtrValue ,QtrDesc) VALUES( @StartDate, year(@StartDate), @StartDate + ( 7 - datepart(weekday,@StartDate)), -- Compute Weekending Date Convert(Varchar(5),year(@StartDate)) + Right(('0'+ convert(Varchar(50),datepart(m,@StartDate))),2), -- ex. 200501, 200502.. datename(m,@StartDate), -- set name of the month Convert(Varchar(5),year(@StartDate)) + Convert(Varchar(4),datepart(q, @StartDate)), -- ex. 20051, 20052, 20053, 20054 Datename(yyyy,@StartDate) + ' Q' + datename(q,@StartDate) -- ex. 2005 Q1... ) SET @StartDate = Dateadd(d,1,@StartDate) PRINT @startdate END PRINT 'End Loop' 8 © Chris Bull 2009
  • SQL Server Integration Services (SSIS) 9 © Chris Bull 2009
  • This ETL process imports multiple CSV files containing Job Time Sheets and loads them into a staging database. Upon completion, a status email is sent indicating job statistics and if errors occurred the error log file is attached. 10 © Chris Bull 2009
  • This data flow task for the Job Time Sheets package processes through a single CSV file doing multiple lookups to ensure database integrity. It logs any rows that error out for review and correction. 11 © Chris Bull 2009
  • This VB.Net script was used in this package to keep a running total of the rows processed and the rows that contained errors. ' Microsoft SQL Server Integration Services Script Task ' Write scripts using Microsoft Visual Basic ' The ScriptMain class is the entry point of the Script Task. Imports System Imports System.Data Imports System.Math Imports Microsoft.SqlServer.Dts.Runtime Public Class ScriptMain ' The execution engine calls this method when the task executes. ' To access the object model, use the Dts object. Connections, variables, events, ' and logging features are available as static members of the Dts class. ' Before returning from this method, set the value of Dts.TaskResult to indicate ' success or failure. ' ' To open Code and Text Editor Help, press F1. ' To open Object Browser, press Ctrl+Alt+J. Public Sub Main() Dts.Variables(quot;TotalFilesProcessedCountquot;).Value = CInt(Dts.Variables(quot;TotalFilesProcessedCountquot;).Value) + 1 Dts.Variables(quot;TotalErrorRowCountquot;).Value = _ CInt(Dts.Variables(quot;TotalErrorRowCountquot;).Value) + CInt(Dts.Variables(quot;ErrorRowCountquot;).Value) Dts.Variables(quot;TotalInsertRowCountquot;).Value = _ CInt(Dts.Variables(quot;TotalInsertRowCountquot;).Value) + CInt(Dts.Variables(quot;InsertRowCountquot;).Value) Dts.Variables(quot;TotalUpdateRowCountquot;).Value = _ CInt(Dts.Variables(quot;TotalUpdateRowCountquot;).Value) + CInt(Dts.Variables(quot;UpdateRowCountquot;).Value) Dts.Variables(quot;TotalRowCountquot;).Value = _ CInt(Dts.Variables(quot;TotalRowCountquot;).Value) + CInt(Dts.Variables(quot;FileRowCountquot;).Value) Dts.TaskResult = Dts.Results.Success End Sub End Class 12 © Chris Bull 2009

  • Recommendations Roger Mabry, Student, SetFocus (academic) studied with you “Chris is a dynamic individual who leads by example. His insight to issues & projects are phenomenal. Chris acted as Team leader for the final project. With systems down, Chris persevered as though there were no obstacles to overcome. With 25% of his teams resources eliminated, His team came through on time & under budget. Chris is a quot;GO TOquot; guy & comes quot;Highlyquot; Recommended.” February 5, 2009 Robert Witkowski, Dean of Students, SetFocus (academic) advised you “To Whom It May Concern: It is my pleasure to provide a recommendation for Chris Bull. Graduating from the SetFocus Master’s Program, Chris Bull excelled in our intense, integrated, in-depth, full time Business Intelligence Training Program. I was impressed by Chris’s ability to work with many technologies during his time with SetFocus. Chris has gained experience with the latest Microsoft BI Technologies, including but not limited to: • Microsoft SQL Server Integration Services (SSIS) • Microsoft SQL Server Analysis Services (SSAS) • Microsoft SQL Server Reporting (SSRS) • Microsoft Office SharePoint Server 2007 In addition, Chris has established competency with defining business requirements, designing the Business Process Model and developing, deploying, and managing a BI System. I found Chris’s excellent work ethic was demonstrated by his ability to work in an environment with firm deadlines, very large workloads, and complex specifications. Chris delivers projects in a time efficient manner, is flexible with specification changes and is able to work within teams on assigned projects.
