Logical AND

A logical operator that combines two propositions and outputs 'true' only if both propositions are true.

Logical OR

A logical operator that combines two propositions and outputs 'true' if at least one of the propositions is true.

Set

Represents a collection of distinct elements.

Binary Relation

A relationship between elements of two sets, mapping each element in the first set to one or more elements in the second set.

Classes in Java

Classes provide the blueprint for creating objects in Java. They define data (attributes) and methods (actions) that objects of the class can have.

Wrapper Classes

Wrapper classes in Java allow us to treat primitive data types like integers and characters as objects. This provides the ability to use them with methods designed for objects.

E-R Model

The E-R Model (Entity-Relationship Model) is a way of visually representing the relationships between entities in a database. It helps in designing database structures by showing how different pieces of information are connected.

Normalization

Normalization is the process of organizing data in a database to reduce data redundancy and improve data integrity. Different normal forms (1NF to 5NF) represent increasing levels of normalization.
