ORMs: The Good, The Bad, and The Ugly Performance

Databases can be complex to manage, especially when working with different programming languages. Object Relational Mapping (ORM) helps bridge the language gap between code and databases. ORM is a tool that allows you to work with a database using programming code instead of writing SQL directly. It enables you to perform CRUD operations (Create, Read, Update, Delete) easily. ORM tools can simplify complex SQL queries, making it easier to manage data in a database. For instance, a SQL query can be replaced with a simpler method like `users.GetById(20)`. ORM techniques allow you to save objects to a database without writing SQL queries, making it a convenient and efficient way to manage data. Popular ORM tools include Hibernate for Java, Django's ORM for Python, and Entity Framework for .NET. While ORM has its limitations and trade-offs, it accelerates product development and reduces the likelihood of bugs. By using ORM, developers can save time and focus on other aspects of their projects.
