LPI-Japan, a non-profit distributor of LPIC(Linux Professional Institute Certification) in Japan will start "OSS-DB" exam from July 1st, 2011. LPI-Japan is known as one of the largest distributor of LPIC in the world(according to LPI-Japan they have distributed 164k LPIC so far).
According to LPI-Japan, OSS-DB will be ready for several open source databases in the future. However the initial version will only support PostgreSQL(!)
Representatives from Fujitsu, Hitach, Miracle Linux, NEC, NEC Soft., NTT, and SRA OSS attended the press announcement event.
I hope OSS-DB will significantly contribute to making PostgreSQL more popular in Japan.
