The GdaDataModelBdb object allows to access the contents of a Berkeley DB database as a GdaDataModel object.
By default the resulting GdaDataModel contains only two columns (named "key" and "data") of type
GDA_TYPE_BINARY, but this object can be subclassed to convert the key or data part of a BDB record
into several columns (implement the create_key_columns(), create_data_columns(), get_key_part(), and get_data_part() 
virtual methods).
Note: this type of data model is available only if the Berkeley DB library was found at compilation time.

GdaDataModel * gda_data_model_bdb_new (const gchar *filename,const gchar *db_name);
Creates a new GdaDataModel object to access the contents of the Berkeley DB file file,
for the database db_name if not NULL
| 
 | name of the file containing the database | 
| 
 | the name of the database within filename, orNULL. [allow-none] | 
| Returns : | a new GdaDataModel. [transfer full] | 
const GSList *      gda_data_model_bdb_get_errors       (GdaDataModelBdb *model);
Get the list of errors which have occurred while using model
| 
 | a GdaDataModelBdb object | 
| Returns : | a read-only list of GError pointers, or NULLif no error has occurred. [element-type GError][transfer none] | 
void                gda_data_model_bdb_clean_errors     (GdaDataModelBdb *model);
Reset the list of errors which have occurred while using model
