You are evaluating moving the data from WebData1 to an Azure SQL database. You need to recommend a solution to generate the consolidated report for billing. The solution must meet the business require

SQL Server Integration Services (SSIS) is primarily an ETL tool for data migration and transformation, not a real-time cross-database querying solution for consolidated reporting.

SQL Server Analysis Services (SSAS) is used for analytical processing and business intelligence, often through OLAP cubes, which is a different architectural approach than directly querying across distributed databases for consolidation.

An elastic database job is used for executing T-SQL scripts across a group of Azure SQL databases on a schedule, typically for management or maintenance tasks, rather than for generating consolidated reports via a single query.

An elastic query allows querying data across multiple Azure SQL databases using a single connection, enabling the consolidation of data from various sharded databases for reporting purposes without requiring data movement. This capability is ideal for generating a unified billing report from data distributed across several Azure SQL databases.
