Logical Data Independence is the ability to change the conceptual scheme without changing. Physical security measures are taken in order to protect these assets from physical threats including theft, vandalism, fire and natural disasters. PL SQL basically stands for "Procedural Language... SQL stands for Structured Query Language, which is a computer language for storing, manipulating,... What are sub queries? Multiple layers of defense can isolate and protect data should one of the defense perimeters be compromised from internal or external threats. Logical and physical database models are required in order to visually present the database that has been proposed for a certain business requirement. Privacy Policy You can use this stored data for computing and presentation. Data security, including logical security (authorization, authentication, encryption and passwords) along with physical security (locked doors, surveillance or access control), has ⦠A DBMS requires a basic architecture and structure to handle the process and files related to the database software, which means that a physical and logical architecture of an Operational System must exist.

Logical Data Independence. Hides storage details of the internal/physical level. The physical data model constraints such as size, configuration and security can vary based on the underlying database ⦠It is the process of making a description of the execution of the database on secondary storage, which describes the base relations, file organizations as well as indexes used to gain efficient access to the data and any associated integrity constraints and security measures.
