| Abstract: |
We develop a heterogeneous fusion system, which consists of two function modules: AutoDB module
and integration module. The AutoDB module is to automatedly create
databases and sky partitioning index. The integration module
realizes the cross-match task between MySQL databases with HTM
(Hierarchical Triangular Mesh) index, cross-match between PostgreSQL
databases with Q3C (Quad Tree Cube) index, and data integration
between MySQL database and PostgreSQL database with HTM index. We
compare the influence of different sky partitioning algorithms HTM
and Q3C on data integration and the performance of cross-match based
on different database types of MySQL and PostgreSQL. Our
experimental results provide some guide on how to select an index
method and database type. With the help of this system, astronomers
may easily manage their data and cross-match catalogs. |
