PASS European Conference

by Allan Mitchell 8 Feb 2009 15:59
Well it’s that time of year again and I am happy to say I have been chosen to deliver a couple of sessions at this year’s conference.  The PASS European Conference, on April 22nd-24th in Neuss in Germany is a great conference and I had fun last year. I will be doing a pre-conference seminar with my good friend Chris Webb.  It is a beefed up version of a presentation he gave at PASS in the United States last year.   Me, being the SSIS expert, I will be covering that side of things and rewriting Chris’s packages so they're rather more robust; allowing Chris to concentrate on...

More Value From Data Using Data Mining Presentation

by Allan Mitchell 1 Nov 2008 11:37
Here is a presentation I gave at the SQLBits conference in September which was recorded by Microsoft.  Usually I speak about SSIS but on this particular event I thought people would like to hear something different from me. Microsoft are making a big play for making Data Mining more accessible to everyone and not just boffins.  In this presentation I give an overview of data mining and then do some demonstrations using the excellent Excel Add-Ins available from Microsoft SQL Server 2008 SQL Server 2005 I hope you enjoy this presentation http://go.microso...

SSAS Cache Warming Using SSIS

by Allan Mitchell 31 Oct 2008 08:22
Having your users walk into a cold cache on a morning is something that will cause them to have slower running queries initially.  Cache warming takes care of a lot of that by executing typical queries against the newly processed cube and thereby building the cache ready for your users when they get in.  There are a number of ways to warm the cache available. Chris Webb has already blogged about how he has done it and we thought we would show you a variation on that theme. UPDATE: The Trace File Source Adapteris now available. The package is relatively simple.     ... [More]

Building a Successful ETL Project

by Allan Mitchell 28 Oct 2008 09:00
When we are building ETL projects we need to do some planning up front to make sure we have all the things we need to make it a success. Here are some of the things we consider when embarking on an ETL Project. There are two lists. The first is around an ETL Project in general and the second is around things we think about specifically for SSIS. Review target data model Identify source systems (Owners, RDBMS types, Permissions) Analyze and profile source systems (usge patterns, Windows of opportunity) Document source data defects and anomalies (known issues, data profiling) ...

Logical OR in Control Flow to Skip Task

by Allan Mitchell 28 Oct 2008 08:52
Here is an example of how to do something that in DTS we would have had to do some coding in Script.  In our packages we often find the need to follow one path or another in the Control flow based on some condition that exists at runtime.  In the example below we use a variable value to decide what path to take.   Here is the control flow along with the variables pane. The icons on the workflow indicate we have expressions thereon. The expression on the workflow constraint between tasks 1 and 2 is shown here. As you can see we want the workflow to be followed if our variabl... [More]

More value from your data through data mining (Presentation)

by Allan Mitchell 25 Sep 2008 11:35
In this Live Meeting presentation Allan looks at data mining. The presentation is split evenly between demos and talking. Allan will give a brief overview of what data mining is along with some of the terminology as well as looking at what is available to you using SQL Server 2005. For the demos he uses Excel 2007 and the Data Mining add-in to demonstrate how even the least statistically minded of us can get started with this technology Presentation

Advanced Topics in SQL Server 2005 SSIS (Presentation)

by Allan Mitchell 15 Oct 2007 14:00
Download the slides and sample code from the Advanced Topics Using Microsoft SQL Server 2005 Integration Services presentation, first presented at the SQLBits 2007 Community Conference. In this session we looked at some of the not so often thought about areas of the SSIS toolbox. Perhaps they aren't considered true ETL by some people or are simply not seen but we think they are really useful weapons in our ETL armoury. Highlights include: Loading partitions directly Consuming a package in SSRS Using a DM algorithm in the pipeline to see... [More]
