A hypervisor is a software layer, sometimes implemented with hardware assistance, that creates and manages virtual machines by abstracting the physical hardware resources of a host computer and presenting them to multiple isolated virtual environments as if each environment had its own dedicated hardware. The hypervisor sits between the physical hardware and the operating systems running on top of it, intercepting requests from virtual machines for access to CPU cycles, memory addresses, storage devices, and network interfaces, and translating those requests into actual hardware operations in a way that maintains…

Functional dependency is a fundamental concept in database management systems that describes a relationship between attributes in a table where the value of one attribute or set of attributes determines the value of another attribute. When we say that attribute B is functionally dependent on attribute A, we mean that for every valid value of A in the table, there is exactly one corresponding value of B. This relationship forms the theoretical foundation upon which database normalization and schema design are built. The concept was formally introduced by Edgar F….

In a Database Management System (DBMS), ensuring data integrity, consistency, and efficiency is crucial to building a functional and reliable database. One of the primary mechanisms used to enforce these principles is the concept of a unique key. A unique key in DBMS serves as a constraint applied to one or more columns of a database table to ensure that each record within the table is distinct. This unique key constraint ensures that no two rows in the table share the same value in the specified columns. In essence, the…
