| Data Services: DEWI (Data Extraction Web Interface)
System
Overview of the DEWI System
DEWI is a web-based tool that allows users to find and extract variables
from selected datasets within the Stanford University Libraries' social
science numeric data collection. It is available for use by the Stanford
community for research and instruction. The DEWI System was inspired by
the Electronic Codebook (ECB) for Windows that was developed by Dennis
Carroll at the National Center for Education Statistics (NCES).
DEWI provides a one-stop shop where users can locate variables by browsing
through the entire list of variables or searching on keywords within the
variable metadata, such as variable names, labels, descriptions, or value
labels. Variables can then be selected for extraction. Other useful information,
such as variable sample frequencies, descriptions, full-text manuals and
technical documentation, can be viewed within DEWI by clicking the "Codebooks,
etc." button. Once you have finished selecting the variables you
want, you can extract them from the full dataset. The resulting file can
be downloaded in popular statistical software formats to your PC or accessed
directly from your Leland account.
If you are a first time DEWI System user, click on the "Help"
button within any DEWI session, where you will find detailed directions
for selecting and extracting data. Please send us any comments, corrections,
suggestions or errors by clicking on the 'Feedback' button within any
DEWI extraction session. Your feedback will help us to improve the DEWI
System and is greatly appreciated.
