Creating an .mdd file from proprietary metadata
Although UNICOM Intelligence Reporter can read metadata in any format for which a suitable read-enabled MDSC is available, there are performance advantages in using metadata in an .mdd file. This is because when the metadata for the project is stored in an .mdd file, UNICOM Intelligence Reporter caches the metadata and this leads to significantly improved performance. The caching persists between sessions and is updated when you create and edit variables.
UNICOM Intelligence Reporter does not cache the metadata when it is stored in a proprietary format, such as a Quanvert database or SPSS .sav file. However, you can use MDM Explorer to create an .mdd file for use in the UNICOM Intelligence Reporter project. This is particularly recommended when using a data set that contains a large number of variables.
1 Open MDM Explorer.
2 On the File menu, click Open MDSC.
This opens the Open Metadata Source Component dialog box.
3 In the Files of Type list, select the required type of files. For example, for a Quanvert database, select Quanvert Project Files.
4 Browse to the folder in which the proprietary metadata is located, and then double-click the required file.
5 On the File menu, click Save As.
6 In the Save Metadata Document As dialog box, enter a name for the .mdd file, and then click Save.
