Al zolang Kohera bestaat, staat Microsoft als leider in de rechterbovenhoek van Gartner’s Magic Quadrant voor Analytics en BI Platformen. Net daarom hebben we bij Kohera een bewuste keuze gemaakt voor Microsoft Power BI. Het is zowaar de cola van de BI-tools.
We and several other Koherians once again spent New Year’s Eve glued to our radios, wondering if we’d adapted the predictive model successfully enough to get De Tijdloze Top 100 from Studio Brussels right? Find out if we did!
Azure Resource Manager templates are great. Managing the resulting JSON files not so much. So Microsoft launched Azure Bicep. Read how it will help with maintaining your infrastructure as code.
Recently, a long-awaited feature was added to Power BI: Small Multiples. Time to explore our new options of visualizing data!
Deze eindejaarsperiode is er een waarbij heel wat tradities gesneuveld zijn. Gezellig samenzijn met de hele familie of lekker gaan eten op restaurant zitten er niet in dit jaar. Gelukkig zijn er ook nog zekerheden, zoals De Tijdloze van StuBru, die ook dit jaar voor muzikaal vertier zorgt in de laatste dagen van het jaar. En daarbij hoort natuurlijk ook onze voorspelling.
Always wanted to run Python on Azure? We'll show you how with Azure Container Instances.
Microsoft has recently taken us on a word lingo with the launch of Azure Synapse Analytics. At Kohera, we've experienced some confusion in the market between Azure Synapse as a standalone product and Azure Synapse Analytics as a SaaS platform. We guess it's time to set things straight once and for all, or at least for a while.
A client asked if we could provide a simple form of monitoring on a part of a provided solution. For this particular source, our client asked us to send a simple email with record counts to a mailing list. No problem! Let's get to work
Sometimes, Databricks can be a bit sluggish. Caching with, for instance, the Delta Cache Accelerated Worker can help you speed it up. We'll explain how it does that.
For some reason developers like stuffing their SQL with SVFs, and that... makes... it... so... slow. Are SVFs really that bad? And is scalar-valued function inlining useful at all? Let’s walk through it together and find out!
While XML has been suitable as a SQL Server native datatype since SQL 2005, for one reason or the other it’s not often used - with only a very few working examples. This blog post is meant for T-SQL teams looking for a working XML example on SQL Server, including schema binding and XML indexes.
What can go wrong when you combine memory-optimized tempdb with the resource governor? If you are using SQL Server 2019 you’ll see that one of the new features allows you to convert some tempdb system tables in in-memory OLTP.
Naar aanleiding van een migratieproject bij een van onze klanten, kreeg ik inspiratie om enkele zaken rond Partitioning uit te klaren. Partitioning is geen performance feature, maar is voornamelijk een methode om het management van grote tabellen te vergemakkelijken.
Allocating budgets on a different level is not easy to manage in DAX. It was (and still is) a DAX struggle for me. This blog post will guide you through the different steps I took to easily manage the different granularities (and write easy DAX afterwards) by allocating budget on day level using Power Query.
Kohera’s Modern Data platform does not come with a canned data model by default. This makes the framework extremely flexible to adapt to a variety of project workflows, but it also means during the Analysis phase we will need to think about how to structure the data before continuing. A blogpost.
Some of our customers want us to import their data from a standard on-premises or cloud-based (Azure) SQL-database, others want us to import their data from a REST API. If ever, you’ll have to import data from a REST API, you’ll surely encounter some obstacles.
Azure SQL Database serverless is a new compute tier made for single databases. This new model automatically scales the compute based on the actual workload per second. This means that you only have to pay for the compute resources (memory & vCores) you use. But there's more...
In a previous blogpost, we already explained how to make a date table in Power BI with DAX. Besides the dates you can add extra properties for each date: year, month-names, weekday-names,... But what about hours and minutes? In this blog and video, we'll show you how to create time tables in Power BI.
