METHOD & APPARATUS FOR ASYNCHROINZED DE-SERIALIZATION OF E-R MODEL IN A HUGE DATA TRUNK

A computer-implemented method for importing data for an Entity Relationship (E-R) model includes receiving an exported E-R model data file of the E-R model, and determining a dependency type correlation of an entity and importing the entity directly if the determined dependency type is one of weak correlation and no correlation. The method also includes determining whether the imported entity with no correlation or weak correlation affects an entity recorded in a strong correlation table, and storing the entity in the strong correlation table until a minimum reference number of a strong correlation is satisfied if the dependency type correlation is strong. The method further includes importing the entity recorded in the strong correlation table, and deleting the entity recorded in the strong correlation table from the strong correlation table when the imported entity with no correlation or weak correlation affects an entity recorded in the strong correlation table.
