ORM is bad – can we offer an alternative?

It’s a well-known fact, that although the database performance is great, and each query is executed in milliseconds, the overall application response time may be slow, making the users wait for a response for extended periods of time. The problem is not the database, but the way the application developers communicate with the database – using Object-Relational Mappers (ORM). The only way to change this behavior is to provide application developers with a tool, which is as easy to use, as an ORM, but which will allow escaping the common ORM pitfalls. That’s why we developed NORM – No-ORM Framework. To facilitate the adoption of the No-ORM approach, we developed a set of generators of user-defined types and functions. The input data is presented in a form of annotated JSON schema, which makes them easy to use by both database and application developers.
