Answer 1

Answer:

An entity set is a set of ‘entities of the same type’ that share the same attributes or properties.

Explanation:

In DBMS related concept, an entity set can be referred as any kind of object having a conceptual based existence (examples like company, job, etc) or a physical existence (examples like office, house, etc). There are two entity sets namely weak entity and strong entity set.  

A strong entity set consists of enough attributes for unique identification. A single rectangle is used for representing it. A ‘weak entity’ set that does not contain enough attributes for ‘unique identification’. A ‘double rectangle’ is used for representing it.

Answer 2

Introduction:

An entity set is a collection of the 'entities of the similar  kind' with similar qualities or features.

Explanation:

A set of entities of the same kind is referred to as an entity set (e.g., all persons having an account at a bank). Entity sets do not have to be disjoint. For instance, the entity set employee (all the bank workers) and the entity set customer (all the banks customers) may both have membership in common.

Therefore, the blank is to be filled by entity set.
