Companies to Collaborate on Highly Scalable Distributed Database Environments; NTT Group Makes Equity Investment in EnterpriseDB

TOKYO -- (Marketwire) -- 10/07/08 -- Nippon Telegraph and Telephone Corporation (NTT) (NYSE: NTT), the largest telecommunications company in Japan, and EnterpriseDB, the leading enterprise open source database company, announced today that they have entered into a wide-ranging strategic partnership that includes an equity investment in EnterpriseDB by NTT Investment Partners, Inc. (NTT-IP), a wholly owned subsidiary of NTT. Under the partnership, NTT and EnterpriseDB will collaborate to enhance and extend PostgreSQL and related technologies, especially in areas such as scalability and high availability, which are of particular importance in large-scale distributed database environments in data centers. NTT and EnterpriseDB will also collaborate to drive enterprises, including the NTT operating companies, to adopt PostgreSQL. PostgreSQL is already considered by many to be the world's most advanced open source database and is the foundation of EnterpriseDB's Postgres Plus product family.

Collaboration to Advance PostgreSQL and Related Technologies

The principal goal of the partnership is to add new features to PostgreSQL and related technologies through collaborative contributions to the PostgreSQL community. Initially, NTT and EnterpriseDB will finalize and submit synchronous replication, a key technology for highly available database systems. This technology was originally developed for PostgreSQL by NTT's Open Source Software Center. Additional scalability and high-availability enhancements appropriate for large-scale distributed database environments, including features based on GridSQL, EnterpriseDB's open source parallel query technology, will follow.

Collaboration to Drive Enterprise Adoption

Other goals of the partnership include studying and developing a high availability solution powered by synchronous replication, which will be released as part of EnterpriseDB's Postgres Plus product family in the near future. The solution will enable enterprises to construct reliable systems using PostgreSQL. Also, EnterpriseDB will work with NTT to accelerate the deployment of Postgres Plus and other PostgreSQL-related technologies in the NTT operating companies' operations and business support systems and in other companies.

Extending the partnership between NTT Group and EnterpriseDB, NTT-IP has made an equity investment in EnterpriseDB through its investment fund, NTT Investment Partners Funds, L.P.
