Real-Time Object-Based Database Architecture for Intelligent Networks (RODAIN)

Database technologies will, already in the near future, have a dominant role in telecommunication and data communication networks. The information and knowledge needed in network operations and management will be organized as a logical entity. Due to the world-wide nature of communication the only way to achieve the logical uniformity is the interoperability of autonomous databases.

The research project Darfin, Database ARchitecture For Intelligent Networks, 1993-95, examined database architectures that can fulfill the requirements of Intelligent Networks (IN) and Telecommunication Management Networks (TMN). The current ITU-T Recommendations for TMN are based on object-oriented modelling. In addition, the long-term architecture of IN heavily advocates OO-modelling. Therefore, the project focused on object-oriented real-time databases.

The research project RODAIN continues the work done in the Darfin project. In the project we have designed and specified a real-time object-oriented database architecture for Intelligent Networks and implemented a simple prototype. The current objective of the RODAIN project is to extend the prototype to a distributed real-time object-oriented database that can be used in telecommunication.

Research topics:

• real-time transaction processing,
• main memory databases,
• distribution,
• recovery, and
• fault-tolerance.

The industrial partners and financial supporters of the project are Nokia Telecommunications, Solid Information Technology, and Telecom Finland. The RODAIN project is also funded by the Finnish Technology Development Centre (TEKES).

Current members of the research group are Assoc. Prof. Kimmo Raatikainen (group leader), Jan Lindström, M.Sc. Tiina Niklander, B.Sc. Pasi Porkka and Ph.Lic. Juha Taina.
