A breakthrough! I have finally figured out how to retrieve records from the database using these modules. This is what I spent most of my day on.

I found a way of viewing the SQL code that is generated by a query, but I may not use that after all. I also found (was referred to) a DBIx::Class mailing list, and I pulled all the archives into one text file for searching. I ended up dumping my big, complicated query and starting from the very basics - getting an example to work, and building up towards the big, complex query little by little. I can now select a range of records based on criteria (<, >, =) for each field, and I can output the values for an individual row. I might even be able to get that whole demo page and graph running on this model by the end of Monday.

We looked at testing the new equipment, but discovered that we need Nate's expertise for that.

Things for Monday:

• Keep building up the complexity of my DBIx query, until I can convert the dbixdemo page to using this DBIx class completely. (See "jun23 cat dbix debug" for current progress.)
• Post the solution to my DBIx questions.
• See jun19 doc - I've started bookmarking action items, and I'm as far as "6. Debugging."
• If I finish all that, look at master todo list
• Start DMP progress report, and check with Dr. Skubic on that

Well, it's the end of my 5th week. I'm halfway done.
