Modernizing Your Data Warehouse using APS
Download as PPTX, PDF5 likes1,609 views
The document discusses modernizing a data warehouse using the Microsoft Analytics Platform System (APS). APS is described as a turnkey appliance that allows organizations to integrate relational and non-relational data in a single system for enterprise-ready querying and business intelligence. It provides a scalable solution for growing data volumes and types that removes limitations of traditional data warehousing approaches.
