A data exploring application is defined for communicating with different types of data sources comprising data sets. The data exploring application includes an interface and a back-end module. The interface receives requests for connecting with a data source of a defined type. The type of the data source is associated with specific requirements for establishing the connection. The interface receives requests for exploring a hierarchy of data sets of a selected data source from the connected data sources. The interface communicates with a back-end module of the application to provide data associated with requested hierarchy levels from the hierarchy of the data sets. Based on received responses from the back-end module of the application, browsing and editing options are generated at the interface for receiving a selection of a data set from the hierarchy of data sets of the selected data source.
