DM: Web DW JOBS WITH CNET.COM (new jersey)

About the department
The CNET data warehouse (DW) is being developed to allow the extraction of
value from the several million transactions we collect each day,
transactions in the form of user requests for Web pages. The DW will be the
authoritative source for raw transaction data and will be available on a
daily basis for ad hoc queries and data mining. In addition, the raw data
will be summarized each day into auxiliary databases, where it will be used
to generate standard reports, as well as to support simpler ad hoc queries.

The DW consists of a Sybase IQ Server and several report-generating and
query tools, along with a developing infrastructure consisting of data
movement, cleaning, and loading tools, as well as metadata and reporting
systems.

The data warehousing group is responsible for: architecture, development,
documentation, and maintenance of the DW systems; definition, documentation,
and maintenance of DW metadata; generation and production of reports
(standard and custom); fulfillment of internal customer needs related to
data analysis and reporting.



No phone calls will be accepted for help wanted positions.
