Managing Concurrent Access to Data in Database Sytem

摘要

A method for managing access to data in a database system includes receiving requests to update data stored in one or more fields of a record in a database table. The method further identifies lock information of the one or more fields from a look-up table associated with the record. The look-up table associated with the record includes lock information of each field of the record. The method then handles the requests based on the identified lock information of the one or more fields.
