Hierarchical Data Sources
Logi JReport Designer directly supports XML format data source by wrapping the provided Hierarchical Data Source (HDS) API. Logi JReport Designer's built-in classes can implement the XML format hierarchical data source interface. You can directly import an XML data source to a catalog using the Catalog Manager.
Logi JReport Designer supports both general hierarchical data sources and hierarchical data sources with a parallel structure (parallel HDS). The way of using a parallel HDS is the same as with general HDS. There are however, some key points that you should be aware of when you use a parallel HDS to develop reports. For details, see Example 2: Developing a Report from a Parallel HDS.
