One area I’ve learned a lot in is using Git submodules to administer plugin-heavy applications like Moodle or WordPress. I made a short video walking through the process of adding a Moodle plugin to a repository as a submodule. Enjoy!
This is going to sound stupid, but…One thing I didn’t really think about enough prior to starting my current job is just how much working with data is involved. Yes, I know. Information systems. It’s kind of all about data. But when I imagined what this job would entail, I thought a lot about building things, about creating systems that support and spark teaching and learning. The reams and reams of data that go along for the – names, email addresses, course CRNs, logs, files, etc – just didn’t seem that sexy to me.
But after a few months of being a sysadmin, I’m thinking about data more and more. There are the obvious things: am I doing enough to keep data safe in the age of constant breaches? Are we thinking about giving users control of their data in any meaningful way in light of evolving views about digital privacy? These are big questions. But in the day to day, I’m just working with like, rows and rows and rows.
It turns out, people have questions they want
Which instructors used the accessible Moodle theme we provided in their courses?
I accidentally deleted a quiz, is there any way to get the grades each student in my class got on it?
Can you tell me who at the University has not yet completed this mandatory training?
How many people logged into Moodle on the first day of classes?
Here is the CRN numbers of 50 courses – can you get me the course full name, id number, and the instructor of record?
So what have I learned?
Sometimes this data is readily available within an application itself. For example in the recent versions of Moodle each course has a very powerful completion tracking and activity tracking report built-in. It is also be possible to extend this functionality with plugins.
Reports or logs can also generally be exported into a .csv or spreadsheet format. I was already pretty proficient with Excel but I’ve upped my game in the last few months just due to the amount of time I’ve spent in spreadsheets. (I don’t think I’ve opened PowerPoint in that time, I’ve kind of flip-flopped in that regard. Less presenting polished data and more churning through raw data).
In addition to a sheets tool, a good plain-text editor is your friend when data needs to be manipulated to be useful. I’ve been using VS Code and find it really useful for manipulating text, especially the ability to find and replace with a regex expression. This is incredibly handy when you have a comma separated list but it just has to have each item on a new-line to import wherever it is you need it to go.
If built-in reports or exported info isn’t cutting it, I’ve been going straight to the source itself: typically the Moodle database accessed by PHPMyAdmin. This lets me run SQL queries in a pretty friendly GUI environment and export the results. I’ve found that simple SQL itself is relatively easy to write – it’s understanding the complex structure of a huge relational database, how the tables need to be joined, and thinking through the links between tables that takes a bit of time. But, I am getting faster at this process – I find sketching the query out and making kind of a map of the relevant tables and fields helpful – and this is what has allowed me to do things like recover the grades of a deleted quiz or return a list of instructors who have used a certain theme.
