Abstract
The use of graph databases has grown over the years, creating the need to use many of the features available in relational databases. Several of these features are already in use, but since graph databases are still in a development phase, many concepts supported in relational databases are still not supported in graph databases. Neo4j supports data entry of various types that can be associated with nodes. However, in the node creation phase it is not possible to specify the property data type. The aim of this paper is to demonstrate how assigning data types to each property can be implemented. Also, it is demonstrated how to check whether a particular data is of the correct type. For that purpose, the change of the syntax used for creating nodes is proposed, and a trigger that would check the correctness of the entered data types for certain attributes is defined.
