Abstract: The present invention discloses a method of managing a complex object in a cloud environment and a system thereof. In the method, an object model of the complex object is obtained, the object model comprises at least information describing a constraint, an attribute and a method of the complex objects. Then, the object model is analyzed to determine at least one desired data storage mapped with the object model and at least one desired data service representing an object service interface for accessing the complex object. Then, at least one data storage and at least one data service for the complex object are generated in the cloud environment based on the desired at least one data storage and at least one data service.
