Both the star and snowflake schemas make use of the dimensionality of data to model the storage system. For the moment, lets ignore the complication that each computer is itself a shared-memory computer, and just say we have one processor in each computer: every separate computer is usually called a node, each node has its own memory, totally separate from all the other nodes, each node runs a separate copy of the operating system.

Useful because the theory can be used in therapy in order to encourage desirable behaviour and reduce un desirable behaviour through punishment eg token economy. MongoDB suffers from memory hot issues as the databases start scaling. A star schema is a logical structure for the development of data marts and simpler data warehouses. So you have a customer identifier which uniquely identifies the customer and you make sure that the identifier is known by the customer (in invoices), so that the customer and the customer service people have a common reference in case they need to communicate.
