Oracle 9 current supports User-Defined Aggregates (UDAGs in Oracle-speak). See http://hippocrates.tops.gwu.edu/oracle/server.901/a- 88856/c14ordb.htm#437280

Microsoft is planning to implement them (UDAggs in MS-speak) after Yukon and the integration of the .NET CLR with the SQL Server engine. See http://research.microsoft.com/~jamesrh/TalksAndPapers/Berkeley.ppt

IBM has funded research through UCLA on this (UDAs in IBM-speak), although with the backlog of clean-up work needed in DB2 to fully transition from the mainframe legacy, its not clear when this might be implemented. See http://www.cs.ucla.edu/~zaniolo/papers/dbpl99.pdf
