Minutes
Testing
SML
- Not a complete set of
- SML repository testing
- Not an offical test pass b/c we did not check in the result of the test pass. David will work with Valentina to check in results.
- One day away from finishing the test pass.
- No major issues
Data Collection
- Test cases checked into CVS
- Covers annotations, the framework, and other misc.
- Includes a setup environment for
- Includes the query layer
- Mostly "happy path" coverage. Will need more..
Data Visualization
- No test coverage at this point
Action Items
- Sheldon will work to get the web page up and running.
- We may need to wrap the test cases from DC in the TPTP
- Hubert will work with Sheldon to automate
Query Interface
Joel presented the [COSMOSQueryInterfaceInitialDesign#High_Level_Structure].
- Do we have an initial list of dialects that we will support? Will need to define the canonical set of these.
- SQL
- XPath
To support anything else, it would be an intermediate transform from/to one of these
- A consumer would like to specify if they get back POJOs or XML
- This is in the response type of the data collection assembly
There are limitations on the XPath query, e.g. grouping would potentially require an additional level of abstraction. Want to avoid the tight coupling of schema to the database.
For things like the "Top 10", this would be a higher level interface/API. Sorting and grouping are major requirements for reporting.
One fundamental issue is how COSMOS is extended. In some sense this is the programming model for COSMOS. Is extension via SQL or via a new "service" Want to promote the introduction of services
How does this work across multiple databases, e.g. CA/Compuware/IBM/TPTP/etc...?
- This needs to be documented.
Build
Hubert working on the build. Target is the end of the week to have this working.
Topics To Discuss Off Line
- Bug: 179828
- Work effort to automate test results
