Data source components (DSCs) enable the UNICOM Intelligence Data Model to read and write data in different formats. Each DSC is specific to a particular type and format of data. However, regardless of the format of the underlying data, the UNICOM Intelligence Data Modelalways presents the data in a standard way. Each DSC has its own rules for interpreting and writing the underlying data.

A DSC can be a case data source component (CDSC), which reads and/or writes response data, a metadata source component (MDSC), which reads and/or writes metadata, or both CDSC and MDSC. DSCs vary in their capabilities. For example, some DSCs can only read data, others can only write data, and some can both read and write data.

The UNICOM Intelligence Data Modelcomes with a number of DSCs. However, it is possible to create your own, and you might want to do this if your data is in a format for which a DSC is not supplied.

The DSCs supplied with the UNICOM Intelligence Data Model are as follows:

Reads and writes case data to an UNICOM Intelligence relational database. The RDB DSC currently supports SQL Serverdatabases only. This is the CDSC that UNICOM Intelligence Interviewer - Server Admin uses to write response data.

Reads and writes case data to a UNICOM Intelligence file-based database. The UNICOM Intelligence Data File CDSC has all the features of the Relational MR Database (RDB) CDSC, but does not require a separate relational database management system. UNICOM Intelligence Files therefore provide a simpler and more portable format for the storage of "offline" UNICOM Intelligence Interviewer - Server Admin data.

Reads and writes metadata and case data in an IBM SPSS Statistics.sav file.

Reads and writes case data in a Quantum-format ASCII data file. Writes metadata in the form of a basic Quantum specification.

Reads metadata and case data in a Quanvert database.

Reads metadata and case data in the standard Quancept QDI/DRS format.

Reads standard UNICOM Intelligencelog files.

Reads case data and metadata from ADO files.

Reads Surveycraft case data and metadata.

Reads In2data case data and metadata.

Reads and writes case data in fixed-format or comma-separated text file that meets the version 2.0 Triple-S standard. Reads and writes metadata in a version 2.0 Triple-S XML file.

Reads and writes tab-delimited, variable length, case data records to a text file.

Reads and writes case data to an XML file. Typically, you use this CDSC when you want to demonstrate or test the transfer of small volumes of case data. To transfer production data, use the UNICOM Intelligence Data File CDSC.

Writes files in the SAS version 7 for Windows, standard-extension format.

Reads and writes metadata in an mrScriptMetadata file.

Translates the routing section of MDM documents into the routing section of an interviewing script.

Converts metadata to a Quancept script.

Reads UNICOM Intelligence Interviewer - Server Admin projects' Sample and HistoryTable tables and creates derived categorical variables corresponding to the columns in those tables.
