Alberto started working with SQL Server in 2000 and immediately his interest focused on Business Intelligence. He and Marco Russo created sqlbi.com, where they publish extensive content about Business Intelligence.
Alberto published several books about Analysis Services, Power BI, and Power Pivot. He is a Microsoft MVP and he earned the SSAS Maestro title, the highest level of certification on Microsoft Analysis Services technology.
Today, Alberto's main activities are in the delivery of DAX and data modeling workshops for Power BI and Analysis Services all around the world. Alberto offers consulting services on large and complex data warehouses to provide assessments and validation of project analysis or to perform specific problem-solving activities.
Alberto is a well-known speaker at many international conferences, like PASS Summit, Sqlbits, and Microsoft Ignite. He loves to be on stage both at large events and at smaller user groups meetings, exchanging ideas with other SQL and BI fans. When traveling for work, he likes to engage with local user groups to provide evening sessions about his favorite topics. Thus, you can easily meet Alberto by looking up local Power BI user groups during scheduled courses.
Outside of SQLBI, most of Alberto's personal time is spent practicing video games, in the vain hope of eventually beating his son.
Provided that you already know what a composite model is, do you also know what the technical details to produce fast and efficient composite models are? In this very technical session we extend the knowledge beyond the basics, understanding the technical details of composite models, so to build efficient systems.
We see in detail good and bad practices.
Every Power BI model has dates and the need of calculation over dates to aggregate and compare data, like Year-To-Date, Same-Period-Last-Year, Moving Average, and so on. Quick measures and DAX functions can help, but how do you manage holidays, working days, weeks based fiscal calendars and any non-standard calculation?
This session provides you the best practices to correctly shape a data model and to implement time intelligence calculations using both built-in DAX functions and custom DAX calculation for more complex and non-standard requirements.
