An entity is said to be existence -dependent if it can exist in the database only when it is associated with another related entity occurrence.
<h3>What is a database ?</h3>
A database in computing is a structured collection of data that is electronically accessible and stored. Large databases are housed on computer clusters or cloud storage, whilst small databases can be stored on a file system. Data modeling, effective data representation and storage, query languages, security and privacy of sensitive data, and distributed computing challenges, such as providing concurrent access and fault tolerance, are all part of the design of databases.
In order to collect and process data, a database management system (DBMS) communicates with applications, end users, and the database itself. The primary tools offered to manage the database are also included in the DBMS software.
