TinyDB is a document-oriented database management system written in Python with no external dependencies.
TinyDB was created in 2013 by Markus Siemens, designed with ease of use in mind at the sacrifice of performance and ACID guarantees (targeting small, standalone apps).
TinyDB does not support concurrent database accesses in general.
Similar to MongoDB, TinyDB relies on a document-oriented store.
TinyDB does not support logging.
TinyDB supports queries via its own custom Query class, through which users can construct and execute most of the standard SQL queries involving string operations and numerical comparisons. It also implements its own query caching mechanism.
Users have the option of either storing their data in a JSON file on disk, or in-memory.
Stored document data is represented internally as a dictionary.
