Hello i have a database of millions of records of lat & lon I wish to find the center where most points are concentrated Example: if 30% of the data is around Location A (within 20m radius), 20% at random Locations, and 50% around Location B (within 20m radius), the final result should tell me the center of Location B (since most points are around that area)

Hi, I'm a DB expert from Bulgaria(EU) with strong experience in wide variety of RDBMS: MySQL, PostgreSQL, MS SQL Server, Oracle, Teradata and a few others.. I have a solid knowledge in writing and tuning complex SQL queries, functions, stored procedures, etc... Besides that, I'm well familiar with the internals of the mentioned RDBMS, so I feel comfortable performance tuning and optimizing the database engines and structures (tables, indexes, statistics). Best Regards, Veselin Z.

Hello. I have over 16 years of .NET programming experience and over 7 years of GIS programming experience and over 7 years of SQL programming experience. I would like to provide a demonstration of a solution where I pick a few random points on the globe and then create random points about them along with noisy data and then show the results of the algorithm(s) (depending on the varied methods used). Once confirming that I will then confirm that the algorithm can scale up to millions of locations. Thanks for reading. -Don
