This volume represents a compilation of topics concerning Firebird’s SQL language written by members of the Russian-speaking community of Firebird developers and users. In 2014, it culminated in a language reference manual, in Russian. At the instigation of Alexey Kovyazin, a campaign was launched amongst Firebird users world-wide to raise funds to pay for a professional translation into English, from which translations into other languages would proceed under the auspices of the Firebird Documentation Project.
