摘要: A method is disclosed for accessing data stored in at least one database, comprising: accessing: model data, representing a model defining the structure of the data, metamodel data, representing a metamodel defining the structure of the model, and rule data, representing at least one rule for accessing the data, said at least one rule specifying at least one constraint in terms of a property of the metamodel; processing the rule data, and accessing the data in said at least one database in dependence on the processed rule data. Related systems, methods and computer systems are also disclosed.
