Microsoft Windows ESENT

Microsoft Windows ESENT is an embeddable and transactional database engine which is used for data storage. You can use ESENT for applications that need reliable, high-performance, and low-overhead storage of structured or semi-structured data. The ESENT engine can help with data needs ranging from something as simple as a hash table that is too large to store in memory to something more complex such as an application with tables, columns, and indexes.
