muesli (hackage): muesli is a simple MVCC document-oriented database featuring ACID transactions, automatic index management and minimal boilerplate.  Import the Database.Muesli.Types module to mark up your types for indexing, Database.Muesli.Query for writing and running queries, and Database.Muesli.Handle for database management. The rest of the modules are internal, but exposed just in case.  See the README.md file for an usage example.
