| Question/Description | Decision | Entry Date | Decision Date | |
|---|---|---|---|---|
| 1 | What does the prototype look like and what is its schedule? | Prototype will be developed using basic Gen3 technology (including existing stack of database and Windmill portal) by January 31, 2019. The system will incorporate data from a cohort of 3 canines as provided by COP. This will allow us to test and understand basic functionality of Gen3. | 10/19/18 | 10/22/18 |
| 2 | What type of underlying data should we use? Graph/RDBMS/Postgres-Graph model used by UChicago? | Will explore using an experimental model, testing for speed and ease of use, after deployment of prototype. Decision is still in flux. In discussions on 12/13/18, it was decided that this will be simplified down to just Graph/Postgres-Graph because the RDBMS model is known to be too inflexible and slow. A new decision will be entered in the log to decide between the two. | 10/18/18 | 12/13/18 |
| 3 | What should we use to Extract, Transform and Load the data? | Several choices have been suggested including KNIME and Pentaho. Creating our own system has not be excluded. Will explore this after deployment of prototype. | 10/12/18 | |
| 4 | For the underlying database, should we use a Graph database (like Neo4J or Neptune) or stick with the Postgres-Graph database that came with the system? | 12/13/18 | ||
| 5 | (predicated by Decision 4) If we decide to go with a Graph database, should we utilize Neo4J or Neptune? TigerGraph is excluded from this decision based on their initial cost ($40K for a 1 year license when only a trial version was desired). | 12/13/18 | ||
