"Extended Stored Procedures" in Oracle?

hello world,

in MS-sqlserver there is the concept of "extended stored procedures", i.e. user-written dll's that can be called like any stored procedure provided with sql-server.

Can anyone point me to a direction whether something similar is offered with Oracle (server running on NT)?

thanks in advance
