A ferroelectric thin film and a forming method thereof are provided. The method of forming a ferroelectric thin film according to embodiments of the present invention comprises forming a sacrificial seed layer on a first substrate, forming a ferroelectric thin film on the sacrificial seed layer, and transferring the ferroelectric thin film to a second substrate. The ferroelectric thin film according to embodiments of the present invention is formed by the method.

Ferroelectric thin film and forming method thereof

A method for managing a virtual database example includes acquiring a first query related to a first object of a first virtual database, issuing an ownership of the first object through a first master front end node corresponding to the first virtual database, and altering first meta information of the first object according to the first query, through a first process which acquires the ownership of the first object. The method also includes requesting an invalidation of a first data dictionary cache about the first meta information of the first object through the first master front end node, receiving a first completion signal indicating that the invalidation of the first data dictionary cache is completed, performing first commit for an alteration of the first meta information of the first object, and collecting the issued ownership of the first object.
