Mnemona

Mnemona is a very simple and quite general scheme for managing object-based information; simple enough for use by non-technical users (with a suitable GUI) but also capable of supporting large, complex applications. It provides much more flexibility and much simpler application development than either relational databases or existing object databases. It is designed to overcome well known limitations of the relational model and to strike a balance between unstructured object databases and the overly restrictive structure of the RDBMS. It is written entirely in Java and its atomic data elements are Java objects; any serializable Java object can be stored. Its design makes it easy to build general purpose tools for manipulating information stored in Mnemona data sets.
