\begin{abstract}
The electronic health record (EHR) is (ideally all) patient medical information (including current and historical) from multiple sources, accessible from any location by any provider caring for the patient. An electronic health database is a kind of a multimedia database containing both textual information about the patient's health status and a set of x-ray, CT, MRI, etc.\ images in EHRs. Pieces of medical information to be transferred from one database to another are called messages. In the last decade, the usage of health databases based on relational database management systems became more and more popular. But there is a big disadvantage of them, namely, that they are not standardized yet and therefore they can hardly interoperate (with each other and other systems, as well). Hence, the information flowing between such health databases is very difficult and laborious. 

Nowadays, much effort has been taken to standardize the EHR systems to ease messaging between health databases. In the EHR standard, the model is based on object-oriented technology, and the common language for sending messages is XML. At this point, the need for storing sent and received messages arises. To reach this goal, we have to create a database where such XML messages can be stored and processed, and should give a framework to query them. Several requirements against EHR systems include to be interactive, interoperable, secure and real-time which are also addressed by traditional relational and object-relational databases so it is straightforward to use such a DBMS for data storage.

In our lecture---beyond the opportunities of using XML---we will show some of the various tasks to do about the introduction of the EHR standard and we will show the foundation of an Electronic Health Database based on the features of Oracle 10\textsl{g}.
