Analysing PingER data
After selecting the section of the data that will be published in RDF, a simple conceptual model was designed based on the PingER data characteristics: each measurement is basically defined by a ping sent from a source (or monitor) node to a destination (or monitored) node, sent in a determined time, and related to a specific network metric. Additionally, the data is accumulated in a historical base within the years and can be used to support to decision making. Data with these characteristics can be modeled using a well-known and studied data model: star schema (Learn Data Modeling, 2012), which the designed conceptual model was based on.
