ORMkerroksen

ORMkerroksen is a Finnish term that translates to "ORM layer" or "ORM layer" in English. It refers to a software development technique that bridges the gap between object-oriented programming languages and relational databases. Essentially, an ORM layer allows developers to interact with database records using objects within their programming language, rather than writing raw SQL queries.

This approach abstracts away the complexities of direct database manipulation. Instead of constructing SQL statements to insert, update, delete, or retrieve data, developers work with objects that represent tables and their rows. The ORM layer then handles the translation of these object operations into the appropriate SQL commands and manages the mapping between the object model and the database schema.

Common benefits of using an ORM layer include increased developer productivity, as it simplifies database interactions and reduces boilerplate code. It can also improve code maintainability and portability, as the underlying database technology can often be changed without significantly altering the application's core logic. However, ORMs can sometimes introduce performance overhead or present challenges with highly complex queries. Popular examples of ORM frameworks in various programming languages include Hibernate for Java, SQLAlchemy for Python, and Entity Framework for .NET.
