In every big scientific project human influence creates disorder. For an investment as big as NICA it is crucial to organize all the elements and minimize the chaos. One of the ways to achieve this goal is to create an Equipment Database (EqDb). Each component in the EqDb will receive its individual Part Identifier. Naming and Numbering Convention is a document containing instructions for Part Identifier creation. It was based on the existing model from CERN . These Part Identifiers will simplify component identification at the location.
