DNA Data Bank of Japan (DDBJ) began its activities in 1986 in collabor
ation with EMBL in Europe and GenBank in the United States. DDBJ devel
oped a data submission tool called Sakura, by which researchers can su
bmit their newly sequenced data on WWW from every corner of the world.
The data bank also built a database management system (Yamato II), in
corporating the techniques and functions of the object-oriented databa
se, in order to efficiently process the data it has collected. A numbe
r of research activities in information biology are also going on at D
DBJ. Two such activities are also briefly introduced in this report.
