ENTITY CLASS Meaning and
Definition
-
Entity class, also known as an object class or entity type, is a concept in object-oriented programming and database design. It refers to a blueprint or template used to represent a collection of similar objects or entities. An entity class defines the common properties (attributes) and behaviors (methods) that the objects within the class possess.
In software development, an entity class is often used to model real-world entities or concepts. It encapsulates the relevant data and functionality related to the entity. For instance, in a banking application, an entity class "Customer" might have attributes such as name, address, and account balance, along with methods to deposit, withdraw, or query account details.
Entity classes are crucial for building object-oriented systems and databases as they promote code reusability, modularity, and maintainability. They allow developers to create instances of the class, known as objects, which can be manipulated and interacted with. These objects can inherit properties and behaviors from the entity class, enabling consistent and efficient implementation of similar entities.
In database design, entity classes are used in the entity-relationship model, where they represent tables and help define the structure of a database. Each instance of an entity class corresponds to a row in the table, and the attributes of the class become the table's columns. Relationships between different entity classes can also be represented in the model, establishing connections between tables in the database.
Overall, entity classes play a fundamental role in object-oriented programming and database design, providing a framework for organizing and representing real-world concepts as software entities.

Etymology of ENTITY CLASS
The term "entity class" does not have a specific etymology itself as it is a combination of two separate words, "entity" and "class".
The word "entity" comes from the Latin word "ens" which means "being" or "thing". It entered the English language in the late 16th century and refers to something that has a distinct and independent existence or a discrete unit.
The word "class" comes from the Latin word "classis" which originally meant "a division of the Roman people" but later evolved to refer to a rank or category of people or things. It entered the English language in the 17th century and is commonly used to group or categorize similar things or individuals.
When used together, "entity class" generally refers to a category or group of entities that share similar characteristics or properties.
