15 Oct 2015 Patiëntengegevens kunnen niet langer verloren gaan in het Ziekenhuis Oost-Limburg

Werken met een elektronisch patiëntendossier maakt het leven veel gemakkelijker voor iedereen in het Ziekenhuis Oost-Limburg. Het heeft wel een belangrijke implicatie: wat er ook gebeurt, de digitale gegevens mogen niet verloren gaan. De wet vereist ook dat patiëntengegevens tenminste 30 jaar worden bijgehouden. Daarom ging het ziekenhuis op zoek naar een oplossing die hen volledige garanties zou geven op lange termijn, tegen de laagst mogelijke kost.

05 Oct 2015 Creating a scalable tempdb for your cloud servers

When deploying to the cloud one of the hardest challenges is to get tempdb to scale in the same way as your virtual server. Why is this, well as cloud machines are scalable and thus can change configurations during their lifecycle the number of tempdb files should be able to scale accordingly, so the amount of tempdb files becomes a dynamic value. Luckily for us, this parameter changes only after a shut down and restart of your virtual machine, so if we had a script that could adjust our tempdb needs every time the configuration changes we could deploy this and be more at ease.

29 Sep 2015 Master Data Services in real life

Master Data Services is one of the hidden gems in the Microsoft BI Tool stack. As the name suggests the idea is to use the tool to technically support Master Data Management. But what we see in real life is that Master Data Services, although being a good tool, isn’t up to standards compared to the master data management tools offered by other big vendors like IBM and SAP. This doesn’t mean that you shouldn’t use Master Data Services (MDS). MDS has a big added value in lots of Business Intelligence and Data Warehousing projects.

28 Sep 2015 SQL Server virtualiseren, waarom?

Meer en meer krijgen wij als consultant de vraag of het nuttig is om SQL Server te virtualiseren. Buiten het licentieverhaal, waar virtualisatie alleen al een enorme impact heeft, zijn er ook technische redenen om wel of niet te virtualiseren. Dit is vooral zo wanneer de bestaande omgeving veel kleine fysieke servers heeft of enkele grote machines met meerdere instances. In deze post lijsten we dan ook de voor- en nadelen op van het virtualiseren van SQL Server. Monday 28 September 2015 SQL Server

17 Sep 2015 Zien ze het BI-bos nog door de bomen bij Microsoft?

Deze vraag krijg ik de laatste tijd vaak voorgeschoteld van klanten die advies vragen welke richting ze uit moeten met hun Business Intelligence. Sinds de overname van Datazen en de grote update van Power BI afgelopen zomer beginnen alle puzzelstukjes in elkaar te vallen en kunnen we spreken van een compleet BI-platform dat zeer concurrentieel is ten opzichte van de andere spelers in de markt.

10 Sep 2015 Migrating Access 2007 to SQL Server 2014

There comes a time in every SQL Server dba’s life when they will have to consolidate an MS Access database to an SQL Server. It's inevitable and destiny decided that it was my turn today. A heavily used Access database which had almost grown beyond its capacity sealed my fate. It had about 1.2 GB of data and had become extremely slow at executing queries, which was something we could no longer ignore. This was the first Access database I was going to migrate, so I started by doing some research on the good old internet. Many people suggest that making SSIS packages is the easiest way to do this, while others recommend using openrowset or opendatasource. I chose the openrowset technique.

18 Aug 2015 ETL with Direct Database Access versus API/JSON

There is a large variety in possible data sources from which we can extract and that number is not likely going to decrease. The ETL path that has to be taken for each source can vary heavily depending on all kinds of factors including application architecture, company security, departmental policies, etcetera. Middle-sized to large companies tend to use multiple applications from which data can be extracted to feed the greedy monster that is BI.

04 Aug 2015 Excel in SSIS: fixing the wrong data types

Imagine your client gives you an Excel file as the SSIS source for a new project. When you load the data you find that the data type is not aligning as expected and some of the rows are not filled with the data provided. You then try to change the input data type in the Excel source component, but you can’t seem to get the output you want. So what's the problem? Well, let’s take a look at the input.

27 Jul 2015 How to check if you’re running on a Windows Core Edition

While writing my SQL Server template installer, I ran into a big problem – I had to determine if my server was a core edition or not, based on the Windows edition. The biggest challenge was that it had to be as OS-independent as possible. Our customers run several OSs, so I needed something that could run on Windows 2008 R2, Windows 2012 R2 and be future-proof for Windows 2016.

03 Jul 2015 Chaos in the library

The uniqueidentifier datatype is a 16-byte binary value used as a globally uniqueidentifier (GUID). Developers use it in database models for assigning identifiers that must be unique in a network of many computers at many sites. Also, developers exploit this uniqueidentifier data type inappropriately, assuming this is always the best way to enforce uniqueness in their data model

05 Jun 2015 Executing a stored proc with openrowset query in a SQL Server job across the CMS

Today I came across an issue with my Central Management Server. I have a database on my CMS which has a few tables with details about the server state (memory, disk space, etc.). I wrote a few stored procs to gather this data using openrowset in combination with the server list obtained from the msdb on the CMS.

20 May 2015 SQL Server Upgrade Advisor 2014

Wondering where to start with your dinosaur database servers that are still floating around somewhere in your highly state-of-the-art environment? Oh yes, everyone else may have forgotten about them, but these machines still exist. While everybody is happily doing their job, you still need to maintain the old servers. After all, you're the DBA and your job is to keep these machines alive.

20 Apr 2015 Hesitating about the cloud will cost you flexibility (and money)

Cloud computing is fully mature, so we believe that many of your SQL Server systems could be running more efficiently in the cloud. We are convinced that a cloud model, whether hybrid or full cloud, is in fact the best solution for most of our customers. The only questions that remain are: when are you going to migrate and with which model?

06 Apr 2015 Hacking the Central Management Studio (CMS)

With this post I want to show you how you can make a central management server (CMS) selective for different user accounts so that you can use public and management roles, only showing the servers that are necessary to do your job. This enables you to only maintain one CMS, but show different servers (and even groups) dependent of your role (operator, junior DBA, Sys DBA,…) these roles are only limited by your needs and imagination. First I looked into Row- and Cell-Level Security
