This is a list of all the tables in the database that are relevant to data entry and maintenance, as well as most analysis applications. These are all the tables that are visible to the 'reader' login. This doesn't include a variety of tables with application back-end and user data. 

Tables are listed here generally following the structure (cardinality) of ICE-D and by relevance for data entry and analysis.

\\

===Tables used in defining top-level applications===

ICE-D is organized at the very top level by "Applications", or in other words the various research disciplines where cosmogenic nuclides are applied. For example, researchers who reconstruct alpine glacier histories around the world would put their data into the ICE-D ALPINE application. Whereas researchers who use cosmogenic nuclides to constrain fault slip rates by dating offset features would put their data in the ICE-D TECTONICS application.

===Tables having to do with geographic sorting===

Because each sample has geographic coordinates, there is not really any fundamental reason to include any kind of geographic region assignment in the database. However, there are some geographic sorting tables that are mainly used to make the 'browse by site' functionality in the web server easier to use.

===Primary site and sample definition tables===

These tables are used to describe the numerous field and geologic observations for 'surface' samples and 'core' samples collected on landforms. In general, landforms associated with specific geologic events
