Databases are the beating heart of digital transformation. Businesses increasingly realize that having a unified view gives them a competitive advantage in a world where data is king. The task of breaking down those silos will fall to highly skilled DBAs using cool new technologies such as PolyBase [https://docs.microsoft.com/en-us/sql/relational-databases/polybase/polybase-guide?view=sql-server-ver15]. Although it was introduced in SQL Server 2016, PolyBase got a whole lot more interesting in SQL Server 2019 with the ability to query external SQL Server, Oracle, Teradata, and MongoDB using T-SQL. Our world just got a whole lot bigger!
Read on for the full set of reasons. My agreement with this comes with one caveat: DBAs are important insasmuch as they are willing to grow, try new things, and develop skills. If you’re a stodgy type who hasn’t learned a thing since SQL Server 2008, you’ve got a shelf life.
