Exanda - a flexible on-line tabulation system using DDI 3.0
Exanda is an aggregation system for the on-line generation of tables and diagrams (up to three dimensions) based on quantitative data. The output is available in different formats like web pages, PDF for printing, and Excel, SPSS, and DDI 3.0 for further processing. Furthermore a tool (Adobe Flash client) is in development which supports the flexible exploration of the data in the web browser. Exanda uses the new DDI 3.0 at two different places. First, the studies are described in DDI 3.0, this applies primarily to the information about the variables and to the basic study description. Second, the aggregated data is generated on the fly in DDI 3.0 format (ncube). It is used as an intermediate format in the processing stage on the server. Additionally the DDI 3.0 documents can be downloaded as exchange format. Flexible configuration and scalable architecture enable the adjustment of the system to specific needs. Example features: disclosure control of small cell numbers, dynamic language change of content and user interface as well. The presentation will illustrate the features of Exanda and highlight the architecture of the system as well as the adjustment possibilities. On-line demonstration with sample studies will be shown. Exanda heavily uses common open source programs and will be published under a GNU license. |
