Since establishment of World Wide Web a number of e-learning tools and resources have been created and successfully used in every educational institution. Established standards such as IMS and SCORM currently provide means for e-learning asset portability and reuse. Most of such implementations have a database back-end. Data from such a back-end RDBMS can be exported into IMS XML and used by standard compliant e-learning platforms. After reviewing facilitating technologies and similar solutions authors state that there is no viable solution for database to IMS conversion. Next they present own DB-to-IMS XML conversion method. As a conversion example authors introduce and use own developed EduMMDB - a set of e-learning tools with database back-end. After presenting conversion tool ELSTD authors summarize gained experience and possibilities of improvement.
