nor does it contain specific configuration guidance that will define a system for deployment. We attempt to give general information that is helpful in planning a deployment, tuning the configuration, and avoiding pitfalls. The information and advice given here should be regarded as indicative, not ...
It is the logical data model that determines the degree to which the data is normalized and whether, for a given set of related data in the warehouse, the model is implemented as a star or snowflake schema. Physical data model This is the physical implementation of the logical model in a...
With Amazon Redshift, you can get insights into your big data cost-effectively using standard SQL. You can set up any type of data model, from star and snowflake schemas to simple denormalized tables for running any analytical queries. To operate a robust ETL platform...
