What does the "in-memory" aspect of a data warehouse mean?

  • Data is stored in RAM for faster access
  • Data is stored on cloud servers
  • Data storage on external storage devices
  • Storing data in random memory locations
The "in-memory" aspect of a data warehouse means that data is stored in random-access memory (RAM) for faster access and processing. Storing data in RAM allows for high-speed data retrieval and analytics, as data can be accessed more quickly compared to traditional storage on external devices like hard drives. This leads to improved query performance and faster data analysis.
