/**
* SQLite Datatypes (from http://www.sqlite.org/datatype3.html)
* - NULL. The value is a NULL value.
* - INTEGER. The value is a signed integer, stored in 1, 2, 3, 4, 6, or 8 bytes depending on the magnitude of the value.
* - REAL. The value is a floating point value, stored as an 8-byte IEEE floating point number.
* - TEXT. The value is a text string, stored using the database encoding (UTF-8, UTF-16BE or UTF-16LE).
* - BLOB. The value is a blob of data, stored exactly as it was input.
*
* Adding BOOLEAN results in an INTEGER, but we keep BOOLEAN to indicate the usage!
