Abstract: In one embodiment, an operating system on a computer device interfaces with a graph database that has data nodes interconnected by relationship edges. The operating system generates database instructions that specify a database operation for a target node in the graph database and a node traversal list through the graph database to reach the target node. By then transmitting the database instruction to the graph database, the graph database (e.g., a database management operating system) traverses the specified node traversal list through the graph database to the target node, and performs the database operation on the target node.

Abstract: Disclosed herein are techniques to facilitate the performance database transactions directly by applications employing concurrency control of an in-memory database (IMDB) and the compilation of expressions to accomplish such database transactions. This disclosure describes techniques to facilitate the compilation of programming-language expressions into processor-executable instructions that employ software transactional memory (STM) concurrency control of an IMDB.
