EDS (the DB) is written entirely in Euphoria, and provides very low-level database functionality. It does not implement indexes other than each table has one, and only one, single-key (though not single-field) index. There is no schema (meta- or otherwise) built into the database. In other words, each application usually hard-codes the meaning of the fields and how they relate to each other. You would need to use one of the libraries that are add-ons to EDS that support relational and other standard database functionality. Check the User Contributions section of the RDS website for the various offerings. -- Derek
