| Outline of Final Research Achievements |
Aiming to create core technologies for a data infrastructure on which multiple databases coexists, we will develop a theory of a data model and algorithms, and create a virtual prototype system based on the current database technologies to conduct the proof-of-concept for the proposed theory.
We have proposed a simple theoretical system in which only a pattern matching is allowed for flat text files, and shown that the proposed system can simulate most of operations of the relational algebra. In this simulation, multiple queries are simultaneously processed without loosing data consistency. Moreover, we have proposed a method for processing queries on distributed data stores and presented it at an international conference.
