A connection is required to send queries to mobile business objects and receive data. Configure the properties required to connect to EIS datasources.
The format in which data is communicated depends on the type of datasource. Establish connections by supplying an underlying driver and a connection string that allow you to address the datasource, and provide you a mechanism by which to set the appropriate user authentication credentials and connection properties.
