Method and system for acessing domain specific in-memory database management system

A computer-readable storage medium storing instructions, which, when executed on a processor, performs an operation for accessing a concurrent graph in-memory database system (DBMS), the operation comprising:

• initializing a concurrent graph data structure accessed by a multithreaded application, wherein the concurrent graph data structure includes a factory object configured to instantiate a plurality of objects in the concurrent graph data structure in response to requests from one of the plurality of the threads in the multithreaded application;
• while executing a first thread, of the plurality:
• initiating a transaction, and
• accessing at least a first one of the plurality objects of in the concurrent graph data structure, wherein the first object is configured to maintain concurrency control while being accessed by the first thread as part of the transaction;
• upon determining the transaction is complete, committing the transaction;
• and
• upon determining an exception has occurred, rolling back a state of the first object to undo any changes made while performing the transaction.
