Current sql schema installation has now been automatized and prviously known set of sql steps (sequential execution of different sql files) has been replaced by a single install command. Database still has to be created just as it used to for different platforms (username and password to access it - as well) but it is not needed now to run @populate_schema.sql or update system_configuration after the installer. Instead, it is sufficient to run installer jar in ussual way, known previously, that is: "java -jar installer.jar -url=database_specific_connection_url -user=username -pass=password -install". When installer runs basic install.xml file is executed. This file contains a set of inclusion tags, specifying what other xml file and in what order will execute. These xml files, represent in database independant way (most of the time) previously known '*.sql' files. Each of xml files represents certain database operations available to the installer through special xml tags. Those tags are explained here below:
