Database tables

quiz_dataset_definitions

This table is an indirect extension to the quiz_questions table, because the quiz_question_datasets table can link a question to one or more datasets. Each dataset represents a variable, that is used either in the questiontext or in the answer to a dataset dependent question.

id: int(10) unsigned NOT NULL auto_increment,
category: int(10) unsigned NOT NULL default '0',
name: varchar(255) NOT NULL default ,
type: int(10) NOT NULL default '0',
options: varchar(255) NOT NULL default ,
itemcount: int(10) unsigned NOT NULL default '0',

quiz_dataset_items

Dataset items can be created for each dataset. The quiz_dataset_items table stores these possible values for the variables defined in the quiz_dataset_definitions table.

id: int(10) unsigned NOT NULL auto_increment,
definition: int(10) unsigned NOT NULL default '0',
number: int(10) unsigned NOT NULL default '0',
value: varchar(255) NOT NULL default ,

quiz_question_datasets

The quiz_question_datasets table is used by dataset dependent questionypes (i.e. calculated) to link datasets to questions.

id: int(10) unsigned NOT NULL auto_increment,
question: int(10) unsigned NOT NULL default '0',
datasetdefinition: int(10) unsigned NOT NULL default '0',
