Sharing a database involves allowing multiple users to access the database. The database compiles the query and figures out the correct data points. Data Independence: Data independence is achieved more easily with normalization structure used in a relational database than in the more complicated tree or network structure. By definition, a relation becomes a set of tuples having the same attributes. A relational database allows the definition of data structures, storage and retrieval operations and integrity constraints. Normalization aims at illustrating multiple levels of breaking down the data. These cookies do not store any personal information.

The fact that a relational database has a well-established schema, is a consequence of the fact that it has a well-established set of extensional predicates, which are what allows us to attach meaning to what is recorded in the database, and which are also a necessary prerequisite for us to do so. This can improve the performance of the model. Owing to their advantages and application in the operations of data storage and retrieval, relational databases have revolutionized database management systems. When a data analyst tries to login with a username and password, the database can set boundaries for their level of access, by providing admission only to the tables that they are allowed to work on, depending on their access level.
