Business Case for Data Warehouse System Redesign

Users Survey is a survey conducted among cell-phone users across the USA. The customer prepared a questionnaire and sent to external partners. The partners then conducted the survey using this questionnaire. The survey partners selected the survey participants and our customer was deciding the survey markets. After the survey, our customer partners were sending all the responses from the Participants to customer data warehouse as text files. Our customer system then loaded these files into an SQL Server database and generated all the reports after the relevant data validation and data linking.

Then the reports were available for dynamic reporting via the Customer internet portal as well as static reporting using excel processing in power point formats. Also there was a production process where our customer staff added value to the incoming data by filtering out data under certain conditions, for example when an outage occurred in the collection process, and producing large, static reports with additional market analysis and carrier comparisons.

Key Issues impacting to Data Warehouse System Redesign

Data model of existing databases was used wherever it was possible. The new ETL, reporting and security solution required significant modifications to the existing system model. All possible manual ETL tasks were automated.

The customer provided not all business rules for development of tool question, answer and sub-group references.
