You need to create a release pipeline that updates an Azure SQL Database (DB1) using the Azure SQL Database Deployment task. Which artifact type should the pipeline deploy?

A DACPAC (Data-tier Application Package) is the correct artifact type because it is specifically designed for deploying and upgrading SQL Server databases, including Azure SQL Database, in a structured and declarative manner. It contains the schema of the database, including tables, views, stored procedures, and functions, allowing for consistent and repeatable deployments. A BACPAC (Backup and Publish Package) is used for exporting and importing both schema and data, making it suitable for migrating an entire database or creating a copy, but not for incremental schema updates in a release pipeline. An LDF file is a SQL Server transaction log file, and an MDF file is a SQL Server primary data file; both are physical database files and not deployment artifacts used in a release pipeline for schema updates.
