What is Enterprise BI in Azure?
This reference architecture implements an extract, load, and transform (ELT) pipeline that moves data from an on-premises SQL Server database into Azure Synapse.
Where is data stored in Azure?
This data is traditionally stored in one or more OLTP databases. The data could be persisted in other storage mediums such as network shares, Azure Storage Blobs, or a data lake. The data could also be stored by the data warehouse itself or in a relational database such as Azure SQL Database. The purpose of the analytical data store layer is to satisfy queries issued by analytics and reporting tools against the data warehouse. In Azure, this analytical store capability can be met with Azure Synapse, or with Azure HDInsight using Hive or Interactive Query. In addition, you will need some level of orchestration to move or copy data from data storage to the data warehouse, which can be done using Azure Data Factory or Oozie on Azure HDInsight.
How does data warehouse work?
To move data into a data warehouse, data is periodically extracted from various sources that contain important business information. As the data is moved, it can be formatted, cleaned, validated, summarized, and reorganized. Alternatively, the data can be stored in the lowest level of detail, with aggregated views provided in the warehouse for reporting. In either case, the data warehouse becomes a permanent data store for reporting, analysis, and business intelligence (BI).
