After we communicate in regards to the entity-relationship style, it may be described as interrelated issues of passion in a selected area of data. The elements of a elementary ER style encompass entity sorts and specify the connection between other entities. 

An entity is outlined as an object or an element of information. 

An entity kind refers to a choice of entities with equivalent attributes. 

An entity set is a choice of other entities of the similar entity kind. That stated, an entity kind will also be thought to be because the superset of the entity set since all entities are incorporated within the entity kind. 

13. What do you know in regards to the ACID homes in Database Control Programs?

The transaction is known as a unmarried logical unit of labor that may get entry to and alter the database’s content material. The transactions can get entry to to be had information with the assistance of studying and writing operations. A number of homes observe to acquire consistency in a database after and sooner than the transaction. Those homes are referred to as ACID homes of the DBMS. 

14. Outline the phrases: Aggregation and Atomicity in Database Control Programs.

By means of atomicity, it signifies that both all the transaction takes position as soon as or doesn’t occur in any respect. That stated, the transactions don’t occur partly in any respect. To the contrary, Aggregation is outlined as a procedure the place other entities mix to shape a unmarried entity this is significant as smartly. Entities are in most cases blended since they on my own don’t make a lot sense.
