The core resources in EOxServer are coverages, more precisely GridCoverages. The EOxServer data model adopts and strongly relates to the data model from EO-WCS (OGC 10-140) as shown below in Figure: “EO-WCS Data Model from OGC 10-140”.
Data Integration Layer¶
Figure: “EOxServer Data Model for Coverage Resources” below shows the data model of the coverage resources. Note the correlation with the EO-WCS data model as shown above.
Data Access Layer¶
Figure: “EOxServer Data Model for Back-ends” below shows the data model of the back-ends layer.
Task Tracker Data Model¶
Asynchrounous Task Processing (ATP) uses its own DB model displayed in Figure: “EOxServer Data Model of ATP Task Tracker” to implement the task queueu, store the task inputs and outputs and track the tasks’ status. (For more detail on ATP subsystem see “Asynchronous Task Processing”).
