The In-Memory Column Store is a feature in Oracle Database that allows data to be stored in a columnar format in memory, which can significantly improve query performance for analytic workloads. Here is an example:

ALTER TABLE sales INMEMORY;

This statement enables the In-Memory Column Store for the "sales" table, allowing data to be stored in memory in a columnar format.
