A field map is applied to elements in a data representation of data from a source database to identify schema elements in a schema. Hierarchical relationships between schema elements that are described in the schema are used to construct a hierarchical data representation from the data representation. Based on the hierarchical relationship between two elements in the hierarchical data representation, it is determined that a first database object must be instantiated before a second database object. After ensuring that the first database object has been created and stored, the second database object is created and stored.
