Department of Labor and Industries
Data Warehouse Update Project
The department maintains a large database in what is known as the “Data
Warehouse.” Each month the data warehouse is updated. Until recently, extracting
the data from the agency’s systems and loading it into the warehouse took 48 hours,
preventing other work from being done during that time.
Computer programs were written reducing the time needed to extract, transfer and
load the data, reducing system down time on update weekends by 54 percent.
Results
! Reduced the total monthly data warehouse update process time from 48 hours
to about 22 hours.
! Computer systems are no longer tied up during the entire data warehouse
update, so they are available for other work.
! Reducing the time it takes to do the update frees a staff member from spending
the entire weekend on the project, allowing them to perform more of their work
during normal business hours.
! Reduced mainframe computer usage by two-thirds during data warehouse
updates.
! Reduced computer network line usage for data warehouse updates by 28
percent.
