Storage costs are rapidly decreasing, making it feasible to store larger amounts of data in databases. This also makes it possible to store previous versions of data in the databases, instead of only keeping the last version. Recently, the amount of data available in XML has been rapidly increasing. In this paper, we describe TeXOR, a temporal XML database system built on top of an object-relational database system. We describe the TXSQL query language used in TeXOR for querying temporal XML documents stored in the system, discuss storage alternatives for XML documents in such a system, and some details about the implementation of the current TeXOR prototype.
