The storage and processing of data through a cloud-based system of applications. Master data management. The techniques for managing organisational data in a standardised approach that minimises inefficiency. Extraction, Transform, Load (ETL). Data transformation.
We’re well past the point of realization that bigdata and advanced analytics solutions are valuable — just about everyone knows this by now. Bigdata alone has become a modern staple of nearly every industry from retail to manufacturing, and for good reason. But it’s not the only skill necessary to thrive.
In this blog, we explore best practices and techniques to optimize Snowflake’s performance for data vault modeling , enabling your organizations to achieve efficient data processing, accelerated query performance, and streamlined ETL workflows.
