Bold for Delphi is an advanced Object Relational Mapper (ORM) and application framework. It is designed to significantly increase developer's productivity providing them with the following facilities:

• Object-relational mapping for persisting domain objects
• UML
  Unified Modeling Language
  Unified Modeling Language is a standardized general-purpose modeling language in the field of object-oriented software engineering. The standard is managed, and was created, by the Object Management Group...
  
   modeling of domain classes
• Object Constraint Language
  Object Constraint Language
  The Object Constraint Language is a declarative language for describing rules that apply to Unified Modeling Language models developed at IBM and now part of the UML standard. Initially, OCL was only a formal specification language extension to UML. OCL may now be used with any Meta-Object...
  
   (OCL) as means of making queries (in-memory or to DB)
• In-memory transactions and Undo/Redo functionality
• A powerful mechanism to subscribe to calculated values by derived attribues.

The use

When an application use Bold a model is created with attributes, links and methods. An interface is then generated to the model that the application can use. As the application evolve there come a need to change the model. Then changes to the inteface is generated and a DB-script with SQL of changes to the database. Existing data in database and methods in code is preserved. The programmer can make advanced use of database without touch SQL in code. A good tutorial is found here
