Abstract: Recent systematic wide field imaging surveys, by the optical and near infrared ground based observatories, lead the continuous expansions in amount of astronomical data. Especially, the large catalogs, which contains information on huge number of astronomical objects, can be produced effectively by the evolution in data pipeline software. Therefore we need the database software which can complete the queries in short time on such catalogs, and also enabling fast data inputs to them. We've begun the project to develop the next generation relational database by using Open Source Software (OSS), which is basically supported by the new technique called as HTAP (Hybrid Transactional/Analytical Processing) architecture. Our final goal of this project is realizing the fast search of catalogs produced on each exposures of Subaru telescope's Hyper Suprime-Cam data, and real-time data inputs on them.
