### Data source

The properties of a data source are:

Property Name | Description
--- | ---
- Display Rounding Mode | Specifies the rounding mode for displaying numeric data values in reports and dashboards that are created on this data source. Data Type: Enumeration The following are details about each rounding mode. For more information, refer to http://docs.oracle.com/javase/7/docs/api/java/math/RoundingMode.html. Up Rounding mode to round away from zero. Always increments the digit prior to a non-zero discarded fraction. Example:
  Input Number | Input rounded to one digit with Up rounding
  --- | ---
  5.5 | 6
  2.5 | 3
  1.6 | 2
  1.1 | 2
  1.0 | 1
  -1.0 | -1
  -1.1 | -2
  -1.6 | -2
  -2.5 | -3
  -5.5 | -6
- Down Rounding mode to round towards zero. Never increments the digit prior to a discarded fraction (that is, truncates). Example:
  Input Number | Input rounded to one digit with Down rounding
  --- | ---
  5.5 | 5
  2.5 | 2
  1.6 | 1
  1.1 | 1
  1.0 | 1
  -1.0 | -1
  -1.1 | -1
  -1.6 | -1
  -2.5 | -2
  -5.5 | -5
- Ceiling Rounding mode to round towards positive infinity. If the result is positive, behaves as for Up; if negative, behaves as for Down. Example:
  Input Number | Input rounded to one digit with Ceiling rounding
  --- | ---
  5.5 | 6
  2.5 | 3
  1.6 | 2
  1.1 | 2
  1.0 | 1
  -1.0 | -1
  -1.1 | -1
  -1.6 | -1
  -2.5 | -2
  -5.5 | -5
- Floor Rounding mode to round towards negative infinity. If the result is positive, behaves as for Down; if negative, behaves as for Up. Example:
  Input Number | Input rounded to one digit with Floor rounding
  --- | ---
  5.5 | 5
  2.5 | 2
  1.6 | 1
  1.1 | 1
  1.0 | 1
  -1.0 | -1
  -1.1 | -2
  -1.6 | -2
  -2.5 | -3
  -5.5 | -6
- Half up Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round up. Behaves as for Up if the discarded fraction is >= 0.5; otherwise, behaves as for Down. Example:
  Input Number | Input rounded to one digit with Half up rounding
  --- | ---
  5.5 | 6
  2.5 | 3
  1.6 | 2
  1.1 | 1
  1.0 | 1
  -1.0 | -1
  -1.1 | -1
  -1.6 | -2
  -2.5 | -3
  -5.5 | -6
- Half down Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round down. Behaves as for Up if the discarded fraction is > 0.5; otherwise, behaves as for Down. Example:
  Input Number | Input rounded to one digit with Half down rounding
  --- | ---
  5.5 | 5
  2.5 | 2
  1.6 | 2
  1.1 | 1
  1.0 | 1
  -1.0 | -1
  -1.1 | -1
  -1.6 | -2
  -2.5 | -2
  -5.5 | -5
- Half even Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. Behaves as for Half up if the digit to the left of the discarded fraction is odd; behaves as for Half down if it's even. Example:
  Input Number | Input rounded to one digit with Half even rounding
  --- | ---
  5.5 | 6
  2.5 | 2
  1.6 | 2
  1.1 | 1
  1.0 | 1
  -1.0 | -1
  -1.1 | -1
  -1.6 | -2
  -2.5 | -2
  -5.5 | -6
Is Default | Specifies whether the data source is the default data source for the current catalog. One catalog must have one and only one default data source. Data type: Boolean
Name | Specifies the name of the data source. Data type: String
Pre-join | Specifies whether or not to apply the pre-join information defined on the data source when building a query or defining join relationships in business views in the same data source. Data type: Boolean
