It is the cloud-based ETL and data integration service that allows you to create data-driven workflows for orchestrating data movement and transforming data at scale . Using Azure Data Factory, you can create and schedule data-driven workflows (called pipelines) that can ingest data from disparate data stores. You can build complex ETL processes that transform data visually with data flows or by using compute services such as Azure HDInsight Hadoop, Azure Databricks, and Azure SQL Database. * Additionally, you can publish your transformed data to data stores such as Azure Synapse Analytics for business intelligence (BI) applications to consume.

Data Blending in Tableau

- April 26, 2022

How the data blending works in Tableau? When you use data blending to combine data, a query is sent to the database for each data source that is used on the sheet. The results of the queries, including the aggregated data, are sent back to and combined by Tableau. The view uses all rows from the primary data source, the left table, and the aggregated rows from the secondary data source, the right table, based on the dimension of the linking fields. Data Blending 1-when the dataset is from a different data source 2-Uses only left join. 3-Data can be available at different levels of granularity. 4-Sends separate queries to each dataset, aggregates, and then perform blending Tableau Public Link: https://public.tableau.com/app/profile/arabinda.mohapatra/viz/BLENDING_16509621767950/definitation?publish=yes
