The columns in ODB API files can currently be of following types:
- REAL, single precision (32bits) floating point number,
- STRING,for text columns. Currently limited to 8 characters.
- INTEGER, 32 bits signed integer.
- BITFIELD, for efficient encoding of flags.
- DOUBLE, double precision (64 bits) floating point numbers.
The actual type of a column can be found using odb header tool.
