+ | === Data Layer === | ||
+ | |||
+ | The [[data_layer|Data Layer]] is a relational database running on a MySQL server. It has a pretty standard relational database design based on a hierarchy of sites (a landform or other grouping of samples that should be considered together), samples (which belong to sites), and geochemical measurements of various types (which belong to samples). The [[data_layer|data layer]] page explains how the database is structured. | ||

+ | === Middle Layer === | ||
+ | |||
+ | The [[middle_layer|Middle Layer]] is a set of calculation services that act on raw data pulled from the database (or from anywhere else) and generate derived quantities such as exposure ages. The so-called [[http:// | ||

+ | === Analysis Layer == | ||

+ | An [[analysis_layer|Analysis Layer]] application is anything that takes a set of raw cosmogenic-nuclide data, exposure ages derived from that data, or both, and displays or uses it in some way. The [[http:// | ||
