Blitz

Blitz (or BlitzDB) was created from the beginning to be as small as possible so it can be used with other applications as their data storage engine.

It also has no external dependencies so it won't bring other requirements to any project you may wish to use it with.

Blitz can be used on its own, saving data to local JSON documents, or it can also be used as a frontend to other document-based databases as well (like MongoDB, flat files).

Support for database transactions is scarce, but Blitz's main features and advantages relate to its speed, lightweight seize, and powerful indexing tools.

Features:

• Document-based
• Object-oriented interface
• Its own querying language
• Deep document indexing
• Compressed document storage
• Automatic referencing of embedded documents
• Documentation

What is new in this release:

• Added support for projections and update operations to the MongoDB backend.
