Method and uniqueness constraint management server for managing uniqueness constraints associated with entities

An uniqueness constraint management server for managing uniqueness constraints associated with entities in a graph database, wherein the uniqueness constraint management server comprises:

• a memory;
• a processor coupled to the memory;
• a communicator coupled to the memory and the processor;
• and
• a uniqueness constraint management controller, communicatively coupled to the memory and the processor, configured to:
• receive a constraint specification of at least one entity from a constraint management system;
• receive a configure operation for maintaining uniqueness requirement in the constraint management system;
• determine at least one constraint key based on inputs received for maintaining the uniqueness requirement in the constraint management system;
• create a composite unique constraint based on the at least one constraint key, wherein the composite unique constraint comprises properties of the at least one constraint key and a constraint vertex indicating a class of constraints available in the inputs received for maintaining uniqueness requirement;
• and
• store the composite unique constraint in the constraint specification received from the constraint management system to validate the uniqueness before performing at least one operation on the at least one entity.

A computer program product (CPP) for managing uniqueness constraints associated with entities in a graph database, wherein the CPP comprises:

• a computer executable program code recorded on a computer readable non-transitory storage medium, wherein said computer executable program code when executed causing the actions including:
• receiving a constraint specification of at least one entity from a constraint management system;
• receiving a configure operation for maintaining uniqueness requirement in the constraint management system;
• determining at least one constraint key based on inputs received for maintaining the uniqueness requirement in the constraint management system;
• creating a composite unique constraint based on the at least one constraint key, wherein the composite unique constraint comprises properties of the at least one constraint key and a constraint vertex indicating a class of constraints available in the inputs received for maintaining uniqueness requirement;
• and
• storing the composite unique constraint in the constraint specification received from the constraint management system to validate the uniqueness before performing at least one operation on the at least one entity.
