Data type

A data type is the kind of value we can store in a particular Attribute.

Unlike spreadsheets, where anything can be entered in any cell, in GIS it is necessary to enter data of a specific type for each field.

Data types used in the System:

  1. Time
  2. Date
  3. Date and time
  4. Hyperlink
  5. Whole number
  6. Decimal number
  7. Real number
  8. True/false
  9. Text
