An XML Data Loader which employs the SAX parsing technology, provides an extendible architecture to generate SQL for each type of XML document to be loaded, and leverages multithreading and decoupling of processes to parse an XML file and to update a database. By using object-oriented programming methodologies, the system and method create new instances of the XML data loader for each XML file to be loaded into a database. Thus, many XML data files may be processed and loaded simultaneously, which minimizes system memory requirements, improves system reliability and memory management, and reduces processing time required from the start of processing an XML file to completing its loading into a database. The invention is applicable to other types of markup language documents, as well.

A method according to claim 1, whereby the questions and the number of the questions K presented to the users are changed based on the computed and stored statistical characteristics of the answers accumulated in the data store. 5. A method according to claim 1, whereby the number of questions which are presented to the user of the terminal is at least a minimum number defined in advance and at the most a maximum number defined in advance. 6. A method according to claim 1, whereby the number of the questions which are presented to the user of the terminal is chosen randomly. 7. A method according to claim 1, whereby to all users of the terminals is presented the same number of questions K. 8. A method according to claim 1, whereby the number of questions which are presented to the user of the terminal is at the most a number defined on the basis of the identification of at least one of the terminal and the data network used by it. 9. A method according to claim 4, whereby the questions which are to be sent to the user of the terminal are selected in such a way that every question included in the inquiry will be presented so that at least one of the statistical characteristics, which is computed or can be computed from the answers received to it, is statistically at least as reliable at the selected reliability level as the corresponding characteristic, which would have been obtained by presenting to each respondent all the questions M included in the inquiry. 10. A method according to claim 4, whereby at least one of the questions to be presented to the user of the terminal is selected from the set of those questions, for which at least one characteristic of the computed statistical characteristics deviates from the target value defined to it. 11. A method according to claim 8, whereby at least that question, for which the computed statistical characteristic deviates most from its defined target value, is presented to the user of the terminal to be answered. 12. A method according to claim 4, whereby at least one of the said characteristics to be computed is a common reliability measuring characteristic for this question and for at least another question. 13. A method according to claim 4, whereby at least one of the statistical characteristics to be computed is computed after storing every received answer and the characteristic is stored in the data store of the characteristics. 14. A method according to claim 4, whereby at least one of the statistical characteristics to be computed is computed when a predetermined number of questions have been received. 15. A method according to claim 4, whereby at least one of the statistical characteristics to be computed is computed after a predefined time after computation of some selected characteristic.
