Object-Relational Mapping (ORM) consists of a framework that aims to shorten the distance between the object-oriented model and the entity-relational model, creating a bridge (mapping) between them. With the approach, it is possible to construct systems applying object-oriented, whose objects are persisted in a relational database.

An ORM has several basic methods that will perform the interaction between the application and the database, being responsible for some basic tasks, such as CRUD (Create, Read, Update and Delete), for example. In addition, ORM will manage the details of mapping a set of objects to a database.

ORM minimizes the need to write connection codes and SQL queries. In this way, it is possible to obtain a significant reduction in the application codes, generating a more elegant code and consequently increasing the ease of later maintenance in the application.

It is important to make it clear that using an ORM framework does not completely replace the need to use SQL in your application. Although the ORM satisfies most of the database interaction needs, in some cases there will be a need, for example, for more custom queries, which will have to be performed through SQL. by: Bárbara Ranieri
