Arrays are an appropriate data model for images, gridded
output from computational models, and other types of data.
This talk will describe an array database system based on a
multidimensional data model and a simple query algebra called AML.
To write expressions in AML, it is first necessary to supply a set of
domain-specific functions.  AML can then be used to apply
those functions to arrays in a structured way.  Examples will be
used to illustrate some useful things that can be written in AML,
and to show how AML expressions can be treated declaratively and
optimized by a database system.
