US Patent 9805338 Database system and user interfaces for matching related entities

A database system is disclosed for matching related entities. The database system may gather, for example from one or more external data sources, various data items, and optionally calculate aggregate values related to the entities. The database system may further match related entities based on the aggregate values. Data may be gathered via one or more customized requests via specialized application programming interfaces (APIs). The database system may further advantageously receive responses via the specialized APIs, processes and standardize each response, aggregate the responses, and provide the responses for review via dynamic interactive graphical user interfaces.
