Registering the Medical Storage Data Access Layer

The LEAD Medical Storage Server has two main components that run in different processes:

the user-interface
the DICOM listening service.

My.Medical.Storage.DataAccessLayer must be registered in each of the two processes.

Registering the My.Medical.Storage.DataAccessLayer requires the following steps:

Creating and registering the data access agent, and the data access configuration view
- MyStorageDataAccessConfigurationView
- MyStorageSqlDbDataAccessAgent
Creating and registering the CatalogEntity classes
- class MyPatient : CatalogEntity
- class MyStudy : CatalogEntity
- class MySeries : CatalogEntity
- class MyInstance : CatalogEntity
Creating and registering the classes to extract DICOM data from a System.Data.DataRow
- class MyPatientInfo : IPatientInfo
- class MyStudyInfo : IStudyInfo
- class MySeriesInfo : ISeriesInfo
- class MyInstanceInfo : IInstanceInfo

The following code snippet shows a Configure method which does this:

private static IStorageDataAccessAgent _dataAccess;

public static IStorageDataAccessAgent DataAccess

{

get

{

return _dataAccess;

}

set

{

_dataAccess = value;

}

public static string ServiceDirectory

{

get;

set;

}

static void RegisterInterfaces()

{

DataAccessServiceLocator.Register<IPatientInfo>(new MyPatientInfo());

DataAccessServiceLocator.Register<IStudyInfo>(new MyStudyInfo());

DataAccessServiceLocator.Register<ISeriesInfo>(new MySeriesInfo());

DataAccessServiceLocator.Register<IInstanceInfo>(new MyInstanceInfo());

RegisteredEntities.Items.Add(RegisteredEntities.PatientEntityName, typeof(MyPatient));

RegisteredEntities.Items.Add(RegisteredEntities.StudyEntityName, typeof(MyStudy));

RegisteredEntities.Items.Add(RegisteredEntities.SeriesEntityName, typeof(MySeries));

RegisteredEntities.Items.Add(RegisteredEntities.InstanceEntityName, typeof(MyInstance));

}

static void RegisterDataAccessAgents(string serviceName)

{

System.Configuration.Configuration configuration = DicomDemoSettingsManager.GetGlobalPacsAddinsConfiguration(ServiceDirectory);

if (!DataAccessServices.IsDataAccessServiceRegistered<IStorageDataAccessAgent>())

{

IStorageDataAccessAgent storageDataAccess =

DataAccessFactory.GetInstance(new MyStorageDataAccessConfigurationView(configuration, null, serviceName)).CreateDataAccessAgent<IStorageDataAccessAgent>();

DataAccessServices.RegisterDataAccessService<IStorageDataAccessAgent>(storageDataAccess);

DataAccess = storageDataAccess;

}

else

{

DataAccess = DataAccessServices.GetDataAccessService<IStorageDataAccessAgent>();

}

public void Configure(Leadtools.Dicom.AddIn.DicomServer server)

{

ServiceDirectory = server.ServerDirectory;

RegisterDataAccessAgents(ServiceDirectory);

RegisterInterfaces();

}
