CUD provides a number of interfaces for CUD registered users to access the data. These act as gateways to retrieve data from and provide data to CUD. Besides, users can choose the format in which data retrieved must appear. For example using the Simple Matching and Query interface, users may choose to download results in a comma delimited (CSV) file or in rich meta data with values of each attributes.
Users may choose the format to suit the purpose they are using the data for. It is similarly possible to generate a query, save it and reuse it in more than one interface.
