| Abstract: |
Federating or combining astronomical datasets frequently leads to new discoveries, for example when cross-matching source catalogs. In database terms this requires a spatial join between tables. Two algorithms for spatial joins (pixel-code and R-tree join) were compared, and the performance of three DBMS (DB2, MySQL, and PostgreSQL) was evaluated using large source catalogs. |
