Designated tables as
reference data (Master
data)
Split data into
domains System Integration
Single central data
warehouse—Manually
accessible by most personnel
Stores both operational and historical data
Relational database model is highly unorganized
Allows user to freely input
irrelevant data (garbage data)
Operational databases ETL from central DW and used by modules
Central DW only holds data for operational data
Central DW cannot be accessed directly by personnel
Archival data is stored in the archive DW

UI Issues:
- Poor Usability
- Tedious Tasks
- Redundant steps
Main Tested Functions:
Inventory Module
- Add, Remove, Edit Equipment
Project Management Module
- Create/ Modify Project info

Extended the active life-
time of operational data-
base instances by 230%
Database made further
scalable through rede-
signed relational DB

Eliminated redundant tables and attributes
Constructed conceptual design model (CDM)
Constructed logical and physical design model
Added reference tables and relational design patterns

Extending the use of the current system reduces purchases of addition-
al electronics—reduces electronic waste
Improved accuracy in inventory data allows for better informed
resource purchasing strategies
