Implementing UNIQUE Integrity Constraint in Graph Databases

Databases enable users to store and retrieve data. However, uncontrolled data entry often results in having duplicate or incorrect data stored in the database, which makes it inconsistent. To prevent this, it is recommended to specify integrity constraints in the database. In this paper, the current possibilities in the field of integrity constraints, with special emphasis on graph databases as a relatively new category of NoSQL databases, are discussed. After giving an overview of the current situation regarding integrity constraints in mostly used graph database query languages, a successful implementation of UNIQUE integrity constraint in a Neo4j graph database is shown.
