This document provides an overview of basic concepts in database management systems (DBMS). It defines key terms like database, DBMS, software examples, purposes of DBMS, applications, and terminology. Specifically, it outlines what a database is, the role of a DBMS in providing management and control of data access. It lists example DBMS software and how DBMS reduce data redundancy and ensure security. Applications of DBMS mentioned include libraries, banking, education and telecommunications. Terminology defined includes entity, attribute, record, key, and relationship.

10. Entity
 An entity is any singular, identifiable and separate
object.

11.  Strong Entity Types
 Recursive Entity Types
 Weak Entity Types
 Composite Entity Types
 or Associative Entity Types
 SuperType and SubType Entities
Type Of Entity

12. Attributes
 An attribute is a characteristic in a database
management system (DBMS). An attribute refers to a
database component, such a table.

13.  Single valued Attributes
 Multi valued Attributes
 Composite Attribute
 Simple Attributes
 Stored Attribute
 Derived Attribute
Type Of Attributes

14. Definition of Record
 A record (sometimes called a row) is a group of fields
within a table that are relevant to a specific entity.
 For example,

15. key
 A key is an attribute or a set of attributes in a relation
that identifies a tuple in a relation.
 They are also used to create relationship between
different tables.

16.  Super key.
 Candidate key.
 Primary Key.
 Alternate Key.
 Composite key.
 Foreign key.
Type of key

17. Relationship
A relationship exists between two database tables
when one table has a foreign key that references the
primary key of another table.
