Lite3::DBM is an object that behaves like a Ruby Hash but stores its data in a SQLite3 database table. It is a drop-in replacement for DBM. Values are optionally serialized with YAML or Marshal, allowing (almost) any Ruby type to be stored. In addition, there is rudimentary support for transactions with emphasis on simplicity and safety.

DBStruct is a class that, like Struct, provides a convenient way to create subclasses with named fields that can be accessed via the usual Ruby setters and getters. Unlike Struct, their contents are stored in a SQLite3 database. In addition, each subclass also provides access to the database via an interface that closely mimics a Ruby Hash, including support for enumeration.

DDDr stands for Domain Driven Design Repository. It's a Ruby gem that simplifies the implementation of data repositories in a Domain-Driven Design (DDD) architecture. It offers a clean interface for abstracting data access, allowing you to focus on your domain logic rather than database operations. With DDDr, you can easily swap out data sources without affecting your core business logic.
