Data Type Definitions and Characteristics

Following are descriptions of the Oracle data types used in the LeasePak database. Note that LeasePak does not use all the Oracle data types.

char
Oracle fixed length character string. Typically used to store short-length string data such as keys, four-character codes, and single-character switch values.
Characteristics:
  • length - The maximum number of ASCII or ISO-8859-1 characters the string can contain.

date
Oracle date and time, containing century, year, month, day, hour, minute, and second information.
Characteristics:
  • format - The date format for the LeasePak database. For example, format YYYYMMDD is the 4-digit year number followed by the 2-digit month number followed by the 2-digit day number with no intervening punctuation.

number
Oracle numeric data type. Used for all numbers.
Characteristics:
  • precision - The magnitude and fractional granularity together, meaning the maximum number of places available to both the left and right of the decimal point. Use precision minus scale to determine the maximum number of places available to the left of the decimal point.
  • scale - The fractional granularity, meaning the maximum number of places available to the right of the decimal point.
