It then calls the database interface’s connect() method.When the Database Export Service detects that files are in its queue, it verifies that the database interface class is loaded and loads it if it is not.

The DatabaseAdapter class provides a set of methods allowing the Database Export Service to perform various functions, all of which are explained in the Javadocs. To be recognized and loaded by the Database Export Service, an external database interface class must be an extension of DatabaseAdapter. The DatabaseAdapter class, .DatabaseAdapter, is a base class for building an interface between the Database Export Service and an external database. To fully understand this article, you may wish to reference the RSNA MIRC Source Code.Īs noted above, MIRC provides four classes to encapsulate files of various types. This file is typically configured by the trial administrator through the Admin Service. The Database Export Service dynamically loads the database interface class, obtaining the name of the class from the Storage Service’s trial/trial.xml configuration file. Each of the objects includes methods providing access to the internals of the file, allowing the interface to interrogate the files to obtain some or all of their data to insert into an external system.

It attempts to parse each file to determine its type and calls the overloaded process method of the interface with one of four objects, encapsulating an XML file, a zip file, a DICOM file, or a file of unparsable contents. It provides a queuing mechanism for submitting files to a database interface, relieving the interface from having to manage the queue. The Database Export Service is a component of a MIRC Storage Service. 5.2 Configuring MIRC for Your Database Class.5 Connecting Your Database Class to MIRC.
