Increases in data volumes are having a negative impact on enterprises’ data warehouse programmes, according to a survey from PMP Research.
The research was commissioned by the Evaluation Centre .
Most of the 100 organisations polled (68%) reported that data volumes have increased substantially over the past three years, with a further 25% indicating more modest rises. Only 2% said data volumes have stayed constant over this time period.
Half (54%) of the sample have already initiated data warehousing projects, with 10% currently evaluating their options and 22% considering such a development.
One in five has started a programme within the past year, while a quarter (24%) have had a data warehousing programme for the past two years, and the same proportion (24%) for between three and five years.
The main reason for implementing a data warehouse project is the desire to improve the flow of management information, cited by 61%. However, the accuracy and reliability of corporate information remains a crucial issue for many, with 28% admitting that data quality was “bad” prior to implementing a data warehouse project.
Just 10% described their data quality as “good” before implementation, and none believed it was “excellent“, said the survey. The majority (78%) are using business intelligence (BI) tools to query their data.
However, less than half (39%) of companies say they have achieved the “single view of the customer” which is often seen as one of the critical requirements of a unified data warehousing strategy.
