By Entity various issues will be understood according to the meaning and context in which the word is used.
In general terms, an entity is what it is, that is, it is simply understood as an entity or being.
Meanwhile, one of the most widely used synonyms in this sense is that of individual.
The individual is one, I, taken into account and in relation to a plurality of people.
Meanwhile, at the request of the Philosophy, the word entity has a special consideration since there it consists of the essence of a thing. There is an ontological system that recognizes the existence of something. Now, there are concrete entities that can be seen and touched, for example, such is the case of people and material objects, and also abstract entities, which are those that cannot be seen with our eyes, such as thoughts, properties, ideas.
Regarding the territorial division We can also find there with a reference for the word that occupies us because there are some territorial divisions in a state that are called that way, for example a province, comarca or community can be formally referred to as a sub-national entity. The autonomous communities and the provinces are clear examples of sub-national entities.
On the other hand, When you want to account for and report on the value or importance that a person or object represents, the term entity is often used to refer to this question. So when something is said to have an entity, it is because it has a special relevance.
Too, that community, understood more than anything as a unit because all the elements that compose it, which are various, work according to the achievement of a common objective, it is called entity. Generally, many organizations, companies, such as banks, are often called or referred to as entities.
Of all the financial institutions, without a doubt, banks turn out to be the most popular. Its mission is to attract economic resources materialized in deposits and then lend that money. They can also provide other financial services.
And finally, in the computing context, the concept of entity has a relevant use in two senses, on the one hand and at the request of the databases, an entity is the representation made, either of a concept or of an object that belongs to the real world. The entity must appear described in the structure of the database and following a model, that is, the data will be established with the relationships and restrictions to not only preserve them but also to avoid repetitions. For example, in a school's database, one of the entities will be students, which will also have a set of attributes that will distinguish it: name and surname, address, telephone number, course to which it belongs, among others ...
And in computer programming an entity is a class that has the properties of a series of classes that will succeed it. Thanks to "inheritance" the different classes will be able to enjoy the properties and methods of a parent class. On the other hand, and depending on the structure that has been proposed and the characteristics of the language used, elements of the main class can be taken as a basis to create more complex ones.
