Extraction of data
Data may be extracted at any time from the CallWeb data base and formatted for use with popular data analysis software. CallWeb can create:
The cwExtr (which stands for Extraction) tool is called from the integrated interface. cwExtr compresses the files it extracts into a zip archive. It either sends this zip file by e-mail to the address identified in # Send extractions to or it leaves the extraction on the server. The destination is selected in the cwExtr parameter interface.
In database-to-database mode (requested from the integrated interface, cwExtr can copy data from one CallWeb data base directly into another CallWeb data base. The source and destination data bases can reside in separate servers but they can also be in different instances of CallWeb on a single server or in the same CallWeb instance. In this mode, new data records can be added to the destination data base and existing data records can be updated with the data in the source data base. It is possible to select only a subset of fields to be transferred but system fields (the name of which starts with an underscore) are always transferred. All fields selected for transfer from the source data base must exist in the destination data base but the data base structure may differ between the two CallWeb projects otherwise.
