This paper describes the results of the benchmark of a very large database performed during the months July/August 1995 with the test data set 'Zeeland'. Some important aspects of the tests are using: OME/SOL (Object Management Extension/Spatial Object Library), SLC (Spatial Location Code), and data compression. The results have been compared to the current situation of our main database in Zeeland. In general it can be concluded that the benchmarks requirements are met on the average the check-out times are 10 times faster compared to the current main database partly due to faster hardware, check-in times are speed-up even more. The SLC technique has proven to be a good alternative for spatial indexing within the database, as representative spatial queries are speed up between 100 and 200 times. The SQL (Structured Query Language) queries show the flexibility of a relational database especially valuable are the SQL queries using spatial operators of OME/SOL.
