Azure Analysis Services Overview

Azure Analysis Services (AAS) is a fully managed platform as a service (PaaS) that provides enterprise-grade data warehousing capabilities. It enables users to create semantic data models that can be used to build business intelligence applications, enabling faster insights and more informed decision-making. AAS allows developers to create tabular data models that can be accessed from various BI tools, such as Power BI, Excel, and Tableau.

Key Features and Benefits

Understanding Tabular Models

The core of Azure Analysis Services is its support for tabular data models. These models represent data in a relational format, similar to a relational database, but optimized for analytical queries. Key components of a tabular model include:

DAX (Data Analysis Expressions) is the formula language used to define measures and calculated columns within tabular models. It's a powerful and flexible language that allows for complex analytical computations.

Common Use Cases

Azure Analysis Services is ideal for scenarios such as:

Getting Started

To get started with Azure Analysis Services, you'll typically follow these steps:

  1. Provision an Azure Analysis Services resource in the Azure portal.
  2. Connect to your data sources (e.g., Azure SQL Database, Azure Data Lake Storage, SQL Server).
  3. Design and build your tabular model using tools like Visual Studio with Analysis Services projects or SQL Server Data Tools (SSDT).
  4. Deploy your model to your Azure Analysis Services instance.
  5. Connect your BI tools to the deployed model for analysis and visualization.
