Abstract

In an example embodiment, a method of handling duplicate records in a computer database is provided. A record is received via an API. An item type associated with the record is identified. A duplicate check schema corresponding to the item type is obtained. A string is generated for the record by extracting values for each of a plurality of fields, defined in the duplicate check schema, located in the record and concatenating the values. Then a hash algorithm is applied to the string to create a hash for the record. The hash for the record is compared to hashes from previous records stored in the computer database to identify whether the hash is a duplicate. In response to a determination that the hash is a duplicate, one or more processing rules from the duplicate check schema are executed.
