Snowflake
Snowflake is a modern data storage and analysis platform that companies use to store and make sense of their business information. Think of it like a very sophisticated digital filing cabinet in the cloud that can handle massive amounts of data and let many people work with it at the same time. Unlike traditional systems that need to be installed on company computers, Snowflake runs entirely on the internet (cloud), making it easier to set up and manage. It's particularly popular because companies only pay for what they use, similar to how you pay for electricity at home. Other similar systems include Amazon Redshift and Google BigQuery.
