A single piece of data can have several representations depending on its usage: a string representation, an SQL representation and of course a GValue representation. Conversions from one representation to the other is DBMS dependent as each database can have its own SQL representation rules. The GdaDataHandler object's purpose is to do all these conversions in a easy way. Except when mentioned otherwise, conversions take into account locale settings and DBMS specifications.

To convert a data, one needs to instantiate a new data handler from one of the many classes which implement this interface, or better to get a pointer to a GdaDataHandler object (no need to unref() it after usage, data handler objects are stateless), and so to obtain such a pointer one can:
