Available Data Types
Odysseus provides a wide range of data types for your processing.
Numeric Types
Double
A doubleprecision 64bit IEEE 754 floating point.
Float
A singleprecision 32bit IEEE 754 floating point.
Long
An 64bit signed two's complement integer. Permissible values are 9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 (inclusive).
Integer
An 32bit signed two's complement integer. Permissible values are 2,147,483,648 to 2,147,483,647 (inclusive).
Short
An 16bit signed two's complement integer. Permissible values are 32,768 to 32,767 (inclusive).
Byte
An 8bit signed two's complement integer. Permissible values are 128 to 127 (inclusive).
Char
A single 16bit Unicode character. Permissible values are '\u0000'
(or 0) to '\uffff'
(or 65,535 inclusive).
Boolean
A boolean
with the two possible values: true
and false
.
String Types
String
A sequence of characters. A string can contain up to ~2^{31} Unicode characters.
Date and Time Types
Date
Timestamp
Complex Types
Matrix
A nxm matrix consisting of doubleprecision 64bit IEEE 754 floating point numbers.
Vector
A vector consisting of doubleprecision 64bit IEEE 754 floating point numbers.
List
A list of objects.
The type of objects in the list has to be defined in the schema definition [['timestamp.unixtimestamp', 'List(Integer)']] and can be accessed in expressions: 'timestamp.unixtimestamp[0] = 1162304033'
Optional Data Types
The following data types are not part of the Odysseus Core and may be restricted.
Spatial Data Types (Spatial Feature)
The spatial data types are based on the "Wellknown text" (WKA) format.
SpatialGeometry
A spatial geometry
SpatialGeometryCollection
A spatial geometry collection
SpatialCoordinate
A spatial coordinate with attributes x, y, and z.
SpatialCoordinateSequence
A spatial coordinate sequence
SpatialPolarCoordinate
A spatial polar coordinate with attributes r, and a
SpatialPoint
A spatial point width attributes coordinate and srid.
An example for a data input in this format could be:
POINT(7.129585 53.648660);SRID=4326
or just
POINT(7.129585 53.648660)
SpatialMultiPoint
A spatial multi point.
SpatialLineString
A spatial line string with attributes points and srid.
SpatialMultiLineString
A spatial multi line string
SpatialLinearRing
A spatial linear ring
SpatialLinearRingArray
A spatial linear ring array
SpatialPolygon
A spatial polygon width attributes shell, holes, and srid
SpatialMultiPolygon
A spatial multi polygon
Interval Data Types (Interval Feature)
IntervalDouble
An interval with inf and sup

Probabilistic Data Types (Probabilistic Feature)
ProbabilisticDouble
A continuous or discrete random variable described by a mixture model
Graph Data Types (Graph Server Feature)
