xayadb

xayadb augments XAYA with basic sql query generation capabilities. It includes:

• support for multi-table, and multi-constraint queries
• spatial predicates (for GIS types of database analysis)
• Grouping and Summary functions
• A custom API whose core notion is a "data model" which is a XAYA format graph. Queries are represented as "a path through a data model" and the approprite SQL for that path is generated.

To use modules: download, remove .txt extension and date stamp. Dependencies: xayacore and xayastats modules. The unit testing module test_xayadb provides usage examples.

• xayadb_20060411.py.txt: Xayadb module -- date stamped
• test_xayadb_20060411.py.txt: test_xayadb module -- date stamped
