Power BI for Big Data and the new look of Big Data solutions
New features in Power BI give it enterprise tools, but that does not mean it automatically creates an enterprise solution. In this talk we will cover these new features (composite models, aggregations tables, dataflow) as well as Azure Data Lake Store Gen2, and describe the use cases and products of an individual, departmental, and enterprise big data solution. We will also talk about why a data warehouse and cubes still should be part of an enterprise solution, and how a data lake should be organized.
Fluff, but point is I bring real work experience to the session
You can use enterprise tools, but that does not mean you are building an enterprise solution
Talking point: IT/PowerUser uses ADF/U-SQL. User could also bypass ADLS and go right to source if no cleaning needed
It takes the approach of ELT instead of ETL in that data is loaded into Azure Data Lake Store and then converted using the power of Azure Data Lake Analytics instead of it being transformed during the move from the source system to the data lake like you usually do when using SSIS
Sometimes has data marts (hub-and-spoke)
Crowed sourced career service, smart-phone app emits drivers location

Question: Do you see many companies building data lakes?
Raw: Raw events are stored for historical reference. Also called staging layer or landing area
Cleansed: Raw events are transformed (cleaned and mastered) into directly consumable data sets. Aim is to uniform the way files are stored in terms of encoding, format, data types and content (i.e. strings). Also called conformed layer
Application: Business logic is applied to the cleansed data to produce data ready to be consumed by applications (i.e. DW application, advanced analysis process, etc). This is also called by a lot of other names: workspace, trusted, gold, secure, production ready, governed, presentation
Sandbox: Optional layer to be used to “play” in. Also called exploration layer or data science workspace
Drill to individual driver via Drillthrough

Question: Should SQL Database be considered in the Model & Serve blade, using it as a data mart?
Microsoft Azure supports other services like Azure HDInsight, Azure Data Lake, Azure IoT Hub, Azure Events Hub in various layers of the architecture above to allow customers a truly customized solution.
