A product can be classified as building materials or intangible. A tangible product is a physical object that can be perceived by touch such as a building, vehicle, gadget, or clothing. An intangible product is a product that can only be perceived indirectly such as an insurance policy.

Intangible Data Products can further be classified into Virtual Digital Goods ("VDG") that are virtually located on a computer OS and accessible to users as conventional file types, such as JPG and MP3 files, without requiring further application process or transformational work by programmers, and as such the use may be subject to license and/or rights of digital transfer, and Real Digital Goods ("RDG") that may exist within the presentational elements of a data program independent of a conventional file type, commonly viewed as 3-D objects or a presentational item subject to user control or virtual transfer within the same visual media program platform. Open Source Code, GNU Linux, or even Android, may manipulate and/or convert base Virtual Digital Goods ("VDG") into process-oriented Real Digital Goods ("RDG"), as part of an application process or manufactured service that may be viewed on Personal Data Assistant ("PDA") or other hand-held tangible devices or OS computer.

A third type in this is services. Services can be broadly classified under intangible products which can be durable or non durable. Services need high quality control, precision
