The University of Informatics Science uses the system of software project management (XedroGESPRO) for monitoring and control the activities related to the production of software. The reports are based on a series of indicators to measure the progress of projects managed, among which those related to performance human resources. This system uses the relational model as the basis for storing information and indicators calculated by the technique of artificial intelligence "fuzzy logic" and stored procedures in the database manager PostgreSQL. All this meant a breakthrough and has produced satisfactory results in the last three years of operation, however significant delays are beginning to appear in the retrieval of information in those tables whose growth increases exponentially compared to the rest. This led to the creation of an oriented-graph model using the tool Neo4J, which reduces response times of queries needed to respond to each indicator. This paper presents the results of applying the model in a scenario closer to reality, which shows the decrease in temporal complexity.
