Reference Codes

The application is the sole and exclusive owner of the database instance. Instances can never be changed from another system when the application is running.

The domain model shall not be tainted with active record interfaces or forced inheritance structure. This decision reflects the hexagon architecture.

Unique object identifiers are necessary to identify instances outside the Java virtual machine, such as databases, CSV files or JSON files. Object identifiers shall be managed and allocated through the active record library. The domain model shall not be a burden to managing internal identity tokens.

Extensions shall be provided to support common model concepts. Extensions supporting reference codes, tags, and comments are provided.

We are enthusiasts to follow functional programming paradigm and object immutability. Therefore, the active record library should provide support for classes enforcing immutability.
