Introduction
In this article (Italian), we have already discussed Continuous Integration and DLM. We described the main reasons for putting a database under source control and for testing our databases. In this article, we are going to discuss a real scenario of SQL Server unit testing with the tSQLt framework.
What Is Unit Testing
In computer programming, unit Read More →

Automating Analysis Services Tabular Projects - Part 1: Deployment
My team recently starting using Microsoft’s Tabular Model databases at work, as an intermediate layer between an operational data store and the end users who consume this data from Power BI. Tabular Models are an OLAP technology, providing an in-memory data cube, with measures being defined using Read More →

In Analysis Services, almost every object and workload is programmable, and often there is more than one approach to choose from. Options include writing managed code, script, or using open standards like XMLA and MSOLAP if your solution requirements preclude using the .NET framework.
