How data is stored in memory in DBMS?

Question

Data storage in an in-memory database relies on a computer's random access memory (RAM) or main memory instead of traditional disk drives. Data is loaded into an in-memory database in a compressed and non-relational format. The data is in a directly usable format without the barrier of compression or encryption.

How DBMS is stored in memory?

An in-memory database management system (IMDBMS) is a database management system (DBMS) that predominantly relies on main memory for data storage, management and manipulation. This eliminates the latency and overhead of hard disk storage and reduces the instruction set that's required to access data.

How is a table stored in memory?

The primary storage for memory-optimized tables is the main memory. Rows in the table are read from and written to memory. A second copy of the table data is maintained on disk, but only for durability purposes. See Creating and Managing Storage for Memory-Optimized Objects for more information about durable tables.
