Never ship a broken semantic model again: how to build automated tests in Power BI with user-defined functions

User-defined functions (UDFs) in Power BI let you build reusable, automated tests for your semantic models — so you catch broken measures, duplicate rows, and faulty relationships before they reach your reports. This article walks through how to use UDFs alongside PQL.Assert to standardize testing across your team, and how to automate those tests with Power Automate or a Fabric Notebook.

Add Nodes to SQL Server 2022 and Windows Server 2022 Failover Cluster

I used the guide in a previous tip on Install SQL Server 2008 on a Windows Server 2008 Cluster Part 1 to install a SQL Server 2008 on a Windows Server 2008 failover cluster (WSFC). Now, I would like to upgrade and migrate my SQL Server 2008 failover clusters to SQL Server 2022 running on Windows Server 2022. What is the process for installation and configuration?

How to host an AI text embeddings model for SQL Server using Ollama

When we want to use AI-based comparisons of text, via vector search in SQL Server, we need to first generate embeddings for the text. An embedding is a numeric representation of meaning, usually represented by vectors. In this article, I’ll show you how to use Ollama to host a server locally that can be used to generate embeddings.

Pro Encryption in SQL Server 2022: Provide the Highest Level of Protection for Your Data

This in-depth look at the encryption tools available in SQL Server shows you how to protect data by encrypting it at rest with Transparent Data Encryption (TDE) and in transit with Transport Level Security (TLS). You will know how to add the highest levels of protection for sensitive data using Always Encrypted to encrypt data also in memory and be protected even from users with the highest levels of access to the database. The book demonstrates actions you can take today to start protecting your data without changing any code in your applications, and the steps you can subsequently take to modify your applications to support implementing a gold standard in data protection.

The LLM layer you’re probably missing (LLM gateway pattern explained)

The LLM gateway pattern is a thin service layer that sits between your app and large language model (LLM) providers, centralizing every AI call through a single entry point. It gives you immediate control over routing, logging, retries, fallbacks, and cost tracking – preventing the chaos of scattered integrations, unclear billing, and provider lock-in as your system scales. Learn all you need to know about the LLM gateway pattern in this article.
