As a result, data sources, including object-relational databases, are now faced with a new class of users and applications; customers and programs that would like to deal directly with XML data rather than being forced to deal with the data source's particular (e.g., objectrelational) schema and query language. The goal of the XPERANTO middleware project is to support this new class of users and applications. XPERANTO does this by providing query-able "XML Views" over the underlying objectrelational database. Users can then query and (re)structure XML data using an XML query language, without having to deal with the underlying SQL tables and query language. The XPERANTO system translates XML-based queries into SQL requests, receives the tabular query results, converts them into XML, and then returns XML documents to the system's users and applications.

This paper presents integration from a pr actitioner's perspective - those practical pain points that are not discussed in typical research literature, but b ig enough to warrant careful study in order to realize practically useful integration systems.

We develop a precise syntax and semantics of SchemaSQL in a manner that extends traditional SQL syntax and semantics, and demonstrate the following. (1) SchemaSQL retains the flavor of SQL while supporting querying of both data
