• Zones are generally used to store data about lithostratigraphic units
• Intervals are meant for storing data outside outside “normal stacked strata”
• Micro features that are too fine scaled • Core descriptions & analysis
• Coal beds
• Cuttings
• Detailed lithology/facies mapping
• RFT
• Faulted repeat pay zones
• Drilling events
• Macro features that span zones • Mud weights and properties
• Bio or paleostratigraphic data
• Completion details
• Perf & test data
• Drilling events

Comparing Interval & Zone Data
• Each interval data type (e.g. core, litho) is stored in a unique table
• Occurrences/records of each type are stored within each table
• Record attributes are stored within “Data Fields” that are unique to each table
