25   * An assembler that provides assembly and disassembly of business DTO from/to
26   * their base DTO.
27   * 
28   * During disassembly of business DTO, it is required that all implementations
29   * generate the id (if newly created base DTO) from UUID and use that in mapping
30   * relations.
31   * 
32   * Generic Mapping:
33   * E -> Business DTO e.g. CourseInfo
34   * T -> Base DTO e.g. CluInfo
35   * 
36   * It is a good practice to propagate state from the parent objects through to the children
