Latest Patents

Prasan Roy holds a patent titled "Garbage collection in object oriented databases using transactional cyclic reference counting." This patent describes a reference counting garbage collection process that employs a technique where only the "last" detected strong pointer is followed to an object. Notably, no assumptions are made about the phase locking used in the transaction, and strict Write-Ahead Logging (WAL) is not followed. This method utilizes a relatively restricted local traversal of the object graph, resulting in higher efficiency. In a client-server arrangement, updates made by a transaction running at the client may be reflected at the server after the transaction ends, without the need to force updates to the server before the transaction concludes.
