  4. 4.  A map is a visual representation of an area – a symbolic depiction highlighting relationships between elements of that space such as objects , regions , and themes.  In mathematics: “ Map is often a synonym for function “  Mapping usually refers to map - making and often used instead of cartography
  5. 5.  Mapping term is also sometimes used for geospatial data collection  Mapping a strategic "road map" for execution of plans
  6. 6.  In DDC, the whole of knowledge is divided each of these into ten sub divisions, then each of the sub divisions into ten sections .  Hence, the term decimal classification.
  7. 7. 000 – Computer science, information and general works 100 – Philosophy and psychology 200 – Religion 300 – Social sciences 400 – Language 500 – Science (including mathematics) 600 – Technology and applied science 700 – Arts and recreation 800 – Literature 900 – History and geography
  8. 8.  The notation of DDC is beautifully simple and pure.  A base of ten has become the major characteristics of DDC.  Major characteristic of the notation is it’s hierarchical structure.
  9. 9.  600 Technology 630 Agriculture and related technologies 636 Animal husbandry 636.7 Dogs 636.8 Cats “Dogs” and “Cats” are more specific than (i.e., are subordinate to) “Animal husbandry”; they are equally specific as (i.e., are coordinate with) each other; and “Animal husbandry” is less specific than (i.e., is super ordinate to) “Dogs” and “Cats.”
  10. 10. The seven tables are :  standard subdivision  areas  subdivision of individual literatures  subdivisions of individual languages  racial, ethnic, national groups  languages  persons
  11. 11.  A table of notations designing certain frequently recurring forms or methods of treatment applicable to any subject. For e.g. : 540 Chemistry -09 History ( Table 1) History of Chemistry 540.9
  12. 12.  A table of notations designing geographical areas. For e.g. : 327 Foreign relation -54 India (Table 2) -52 Japan (Table 2) 327.54052 Foreign relation between India and Japan
  13. 13.  This table is used with notations from the literature class (Class 800). For e.g. : 84 French literature -08 Collections of literary text (Table 3B) 840.8 Collections of French literature

  15. 15.  The notation from this table may be used with those numbers from the schedules and other tables to which the classifier is instructed to add. For e.g. : 738 Ceramic arts -089 Racial,Ethnic,National groups ( Table 1) -951 Chinese ( Table 5) 738.089951 Ceramic arts of Chinese
  16. 16.  The notation from this table may be used with base numbers from the schedules and other tables to which the classifier is instructed to add. For e.g. : 220.5 Translation of Bible -31 German language ( Table 6) 220.531 Translation of Bible in German language
  17. 17.  The table is used to denote group of persons For e.g. : -024 Works for specific type of users ( Table 1) 510.24 Mathematics -62 Engineers ( Table 7) 510.2462 Mathematics for Engineers
  18. 18.  DDC is discipline oriented scheme  The DDC is a system of library classification made up of ten classes, each divided into ten divisions, each having ten sections  The notation of DDC is beautifully simple and pure  The scheme is hierarchical , like a family tree
