Record
Entity means a specific thing in both database work and data modeling. An entity is data that can be classified, and has a relationship with other classified data, as in entities.
Entity occurrence in a database refers to a specific instance or realization of an entity type within a database schema. For example, if "Customer" is an entity type, a particular customer, such as "John Doe," represents an entity occurrence. Each occurrence holds unique attributes that distinguish it from other occurrences of the same entity type, typically stored as a row in a table. This concept is essential for organizing and managing data in relational databases.
Record
A record refers to a collection of related information about a specific entity in a database. Each record typically contains fields that represent different attributes or properties of the entity being stored.
Entity instance is a single occurrence of an entity type. Also known as an instance. Unlike entity type, many instances of entity type may be represented by data stored in the database.
A column in a database represents an attribute to the entity that the table is representing. For example, "hair color" is an attribute if your entity is "customers of a hair salon". This would go in a column of the table (entity) titled "customers" in a management system of a hair salon.
