The roles in data

For those who are not familiar with the variations of roles in the field of data, this is what I’ve learned so far about those roles. You have data analysts, data architects, data engineers and data scientists.

A data analyst works on, no surprise, analysing data. Often these are people preparing reports (for instance on sales performance) for management. When working in Microsoft Azure, you would spend a lot of time using Power BI to create reports, using polished data sets to perform transformations and calculations. Your goal is to create visualizations that anyone else in your organisation can easily understand.

To create those polished data sets for analysts to work with, you need a data infrastructure. That’s where the data architect comes in. An architect thinks through what the data needs are on one end, knows the perks of the raw data coming in at the other end and then designs the infrastructure in between.

The data engineer then uses the input from the data architect to build the infrastructure.

Sometimes you want to dig deeper into your data and discover more complex patterns. That’s where the data scientist comes in. These math wizards apply statistical, machine learning and AI models to data and are able to tweak these models using there mathematical knowledge.

I was rather surprised to learn how working in data, a relatively new field to work in, already split up in so many roles. And then I’m not even talking about all the specialisations you could choose within these roles for hard core programmers. For instance my trainer worked for many years solely on optimising SQL statements for a living.

My education prepares me for two roles mainly: the analyst and the engineer. I’m most definitely happy with all the skills I learned about using Power BI. That will help me a lot when I start digging for stories using data sets. The data engineering part is absolutely not my cup of tea. It’s really theoretical and an in-depth crash course on database management and Azure cloud infrastructure. You can compare it to fitting electrical pipes in your home. It needs to be done, otherwise you can’t live in your home, but it’s not as exciting as decorating your home. At least I get more excited about decoration and design than fitting pipes. That said, I’m still very happy to get a solid understanding of the inner workings of databases and the cloud tools one needs to create usable data from raw data. It helps me to be able to instruct others to click the right buttons, write the proper SQL statements and build the pipelines for me, so that I can dig for the data story gold 😉

Dishwasher continued

Huge progress on the dishwasher front! We just had a new machine delivered to our home. Now on to the next task: placing it in the kitchen, fitting the kitchen panel and connect it to water and power.

Our old home

We payed a visit to friends, also former neighbours, in Enschede. Daughter wished to see our old home. As our friends still live in the same neighbourhood we walked there to show it to her. Little has changed in four years. Except for Daughter, who was just under one when we left this house and turned five a month ago. She came to the conclusion that our current home looks prettier. I agree with her.

The dishwasher gamble that turned sour

We should have known better. Five days ago I wrote that the dishwasher we originally ordered wouldn’t fit in our kitchen and thus went back to the shop we bought it from. Then we quickly decided to order another one, to be delivered a week from now. The gamble we took was to order a ‘second chance’ model instead of a new one. That gamble turned sour, but not for the reason I thought it was a gamble (that it was previously repaired). The Man noticed that the credit card was still not credited for the new order and called customer service. It turned out that the entire order, including the appointment for installation, was cancelled without noticing us. We could have been waiting all week, expecting a new dishwasher next Saturday, for nothing. When on the phone the employee offered to place a new order “and that can be delivered tomorrow”. With that promise he forgot that the delay is in the installation. Two weeks, maybe even longer, to make an appointment for that.

Of course we were livid. The Man send a very lengthy e-mail to customer service this afternoon and as I’m writing this we’re waiting for their response.

Considering the shortage in dishwashers, I didn’t wait for the company to come up with a solution. Their own stock is even lower than when we first ordered, three weeks ago. I checked their site but they have absolutely no model left that fits our kitchen. Acting quickly is key, so again I scoured the web for dishwashers. It really feels like a scavenger hunt by now. I ended up with a company in Dokkum, way up north, that has one Siemens model on stock that suits us. We even called the shop, just before closing hours, to make sure our kitchen panel will indeed fit. They don’t do installation, but I’d rather have a machine and find a local professional to pay for the installation (or even try installing it myself!) than end up without a new dishwasher for many more weeks. We placed our order and now we have to wait and see if indeed this dishwasher can and will be delivered soon. Fingers crossed!

Garden update

End of May the never ending autumny spring turned into Summer, creating lots of green to grow and colours to emerge. Some of it has come and gone already, but right now the honey bees (and some solitary (bumble)bees are feasting in our garden. Currently we’re at peak roses (some of which we didn’t cut in time and therefore decorate the apple tree). In contrast to last year, when there was no rain for weeks and weeks in Spring, the new plants are growing and blooming (and of course completely forgot the names of the plants).

Quarantinology

Though talking from the viewpoint of the US, I really enjoyed listening to Allie Ward’s episode Quarantinology. Covid-19 regulations are being lifted, now what? Ward talked to several researchers covering the history of quarantine, what to expect in the near future regarding infection rates and how to deal with settling in to our new lives. Indeed, we’re not getting back to normal. Normal is dead, according to Cole Imperi. Imperi also talks about ‘shadow losses’, things we lost during the pandemic, and our need to grief for them. That part really made sense to me. I highly recommend listening to this episode of Alli Ward’s excellent show.
