Data import

You import data from various heterogeneous data sources, such as XML files or relational databases and combine and represent them in different analysis realms. The analysis realms are saved in their entirety in the analysis server's memory and thus enable quick access to data and their efficient evaluation.

Data import consists of two steps. In the first step, an extractor extracts data from the source system and stores them in PPM system event format in the file system. In the second step, the runtableimport command line program extracts the data from the files stored in the file system and imports them into the PPM system. Both extractors and runtableimport program work with the same data source file that specifies where the data comes from and how they are to be imported into the analysis realms. CTK automatically generates the data source file and stores it as described in chapter Directory and file structure. Detailed information on handling the PPM extractors is available in the documentation PPM Process Extractors.
