Understanding DAC in Data

A Data-tier Application (DAC) is a logical database entity that defines all of the SQL Server objects such as tables, views, and instance objects, including logins, associated with a user’s database. It is a self-contained unit of the entire database model and is portable in an artifact known as a DAC package, or .dacpac.

DAC in SQL Server

In SQL Server, a DAC can be used to extract a database schema, which can be deployed to another SQL Server instance. This makes it easy to move databases between different environments, such as from development to production. The SQL Server Data Tools (SSDT) provides a way to create, extract, publish, and register .dacpac files.

DAC in Azure SQL Database

Azure SQL Database supports DACs as well. A DAC can be used to export a database schema from Azure SQL Database, which can then be deployed to another Azure SQL Database or to an on-premises SQL Server instance. The export process creates a .bacpac file, which is a compressed version of the DAC package. The .bacpac file can be imported into another Azure SQL Database or SQL Server instance using the SQLPackage command-line tool or Azure Data Studio.

In the Azure portal, you can export a DAC package by selecting the Export option for the database. You can also import a DAC package by selecting the Import option for a SQL Server or Azure SQL Database instance.

DACs are a powerful tool for managing database schemas and moving databases between different environments. They provide a portable, self-contained representation of a database schema that can be easily deployed to other instances of SQL Server or Azure SQL Database.
