into broad categories: industry and commerce. Industry refers to economic
activities which are connected with conversion of resources into useful
goods. Industries may be: primary, secondary or tertiary. Primary industries
are connected with the extraction and production of natural resources and
reproduction and development of living organisms, plants, etc. Primary
industries may be: extractive (like mining) or genetic (like poultry farms).
Secondary industries are concerned with using the materials which have
already been extracted at the primary stage. These industries could be:
manufacturing or construction. Manufacturing industries may be further
classified into analytical, synthetical, processing and assembling industries.
Tertiary industries are concerned with providing support services to primary
and secondary industries as well as activities relating to trade.
Commerce includes activities relating to trade and auxiliaries to trade.
Trade refers to sale, transfer or exchange of goods. It could be classified as
internal (domestic) and external (foreign) trade. Internal trade may be
