Disclosed is a system and method for model-driven datastore. The model-driven datastore includes an object persistence model editor for developing specific object persistence models based on an object persistence metamodel. The object persistence model consists of object model, object access pattern and user defined functions. The object model consists of a collection of object definition, said object definition supports at least one basic type or structure type of attributes. The object access pattern defines the access path that are used to retrieve the object instances, where the access path is consists of a collection of actions. The actions comprise at least one of the following a self action, parent action, or children action. User defined functions are declaratively defined and supports group operators. The model driven datastore further includes a model transformer for generating an object index based on object access patterns and executable code for supporting object access patterns and user defined functions and an object store manager for executing generated code that allows applications to create, update, retrieval or persist objects.
