Abstract: The disclosed systems and methods can include receiving data files from various data sources to create a unified database. An appropriate configuration for the data files is determined. Each data file is parsed into cells and associated with an entity. The appropriate configuration is applied to the cells and the cells containing primary keys and foreign keys are identified. The related entities are linked via the foreign keys. The entities are aggregated based on the primary keys. Entities that are duplicates to the entities stored in the destination database are excluded from the aggregate and the aggregate is transmitted to the destination database.
