3. Review - Purpose
Query heterogeneous data sources using standard SQL statements
Achieve database integration and access at the query level
Allow the data to be “black box” whereas users don’t need to have understanding to source, architecture, or technical details

4. Review - Goals Complete the Requirements of CIS895
Successfully Navigate Software Engineering Process
Prove UmbrellaDB Concept
Prove Ability to Process UmbrellaDB Queries
Create easy to use Graphical User Interface (GUI)

7. Project Review - Performance
Key Performance Areas
DataServer Response Time
Although not completely optimized, works well
Efficiencies added in future versions
Data Transmission via Network
Tests Created to Measure Response Time Varying
Network: Local, LAN, WAN
File Type: Delimited, Formatted
Performed 180 Tests to Measure Response Time
Most Results Within Acceptable Limits
DataServer Time consistent
Network transmission times variable

8. Project Review - Reliability
Most Important Factors
Network Related Components of the System
Data Connectors
Router
DataServer
Issues
Socket Dropped Unexpectedly
Delays over the Internet based TCP/IP Connection
Resolutions
Requirement to Build More Error Catching/Handling into Network Related Components

9. Project Evolution Software Development Process (COMET)
5 Iterations of Prototypes (v0.1 – v0.5)
Positive Effects
Better Class Model
More Efficient Design
Negative Effects
Extra time to refine
“Escalating Commitment” in areas (GUI)
So much time investment, hard to start over
1/3/2019

10. Project Management and Control
Technology and Tools
Tools worked well
Good Cost Factor ($0)
Open Source Tools Worked Well
Large Learning Curve for the Project Manager
Processes
Concurrent Object Modeling and Architectural Design METhod (COMET)
Hassan Gomaa - Author
Good for:
Prototyping with Quick, But Not Final Results
Generating Further Requirements and Modeling Ideas
Bad for:
Communication
Tracking “process paper work”
1/3/2019

11. Project Management and Control
Methods
Unified Modeling Language (UML) De Facto Industry Standard
Much to learn
80/20 Tool Approach
Object Constraint Language (OCL)
More Intuitive (for me, at least) Than Other Formalisms
Still Hard to Learn, On an Individual Basis
Time Analysis
Planned hours
Used hours
Schedule Changed Due to Factors Outside of the Project
Less Time Used not Necessarily Positive

13. User Manual - Examples 1/3/2019 To start a new Project:
1) Click the File Menu
2) Click Project
3) A dialog will appear
4) Enter a Project Name
5) Enter a Project Description

14. User Manual - Examples 1/3/2019
The Project Tree will give a visual representation
of all Connections, Data Sources, Data Fields and
Queries that are part of the project’s virtual
database schema. The Meta Data area will
show metadata describing items in the project.
The Status Bar will show what project is
currently loaded and where it physically exists.
The Query Data area is where data will appear
when a query is successfully executed.
