System and method for locking and isolation in a storage platform

The sharing model for file system operations is unified with the transaction and locking model of query language statements to provide an overall framework for locking and isolation in a storage platform (308). Additionally, transactional support is provided for file system operations so that they may be executed in the context of a transaction. Accordingly, a single transaction may include a single file system statement, a single query language statement, multiple file system statements, multiple query language statements, and a combination of file system and query language statements. Furthermore, support is provided for non-transacted file systems statements so that file system statements need not necessarily be executed in the context of a transaction.
