Earn Money with Unused Stuff: A Sharing Economy Data Model

by Emil Drkušić
13 Jun 2018 There isn’t much chance you’ve missed the whole idea of the sharing economy – whether you like it or not. Popularized by companies like Airbnb, Uber, Lyft, and many others, it lets people earn some cash by renting out their unused stuff. Let’s see the data model behind such an application.Got a spare room? Sign up with Airbnb and make some extra money renting it out. Got a car and some free time? Become an Uber driver. And so it goes – the idea behind these companies and many more like them is almost the same. It’s all about sharing a resource with (mostly) strangers, with a perk for both parties. The owner gets money for their unused property, while the customer usually gets a good deal; this should be a win-win situation.

A Grocery Delivery Data Model

by Emil Drkušić
21 May 2018 If there’s a way to order groceries online, why not use it? This article examines the data model behind a grocery store’s delivery system.We still get a special feeling from picking something from the garden and then preparing it right away – but it’s not something we can do often. Today’s fast pace doesn’t allow it. In fact, sometimes it doesn’t even allow us to go to the store to “pick” our groceries. So it makes sense to save ourselves some time and use an app to order what we need. Our order will just show up at our home. Maybe we won’t get that special fresh-picked feeling, but there will be food on our table.

A Children’s Party Data Model

by Emil Drkušić
29 Mar 2018 Organizing children’s parties is not an easy job: everything has to be perfectly planned and delivered. Otherwise, chaos happens. It’s up to the adults – more specifically, the party planners – to take care of everything and do it properly.Is there a better way to do this than to organize everything in a database? We don’t think so!Children’s parties vary a lot. Some are simple, like birthday parties that include just invitations, food (snacks, beverages, and a cake) and maybe a clown or a magician to entertain the kids. Other parties are much more complex. They may require a trip out of town, sleeping accommodations, and many other activities. The more complicated the party, the less room for mistakes. While a clown that’s 10 minutes late isn’t a big deal, no one wants to wait with a group of bored kids for a bus that’s two hours late!

Call up a restaurant, order your favorite meal, and read about a data model that can organize the whole process.Despite an abundance of “time-saving” technology, we seem to have less time to fulfill basic needs – such as eating. If we want to eat something but we don’t have the time (or the skills) to cook it ourselves, we can order food from a restaurant (i.e. a takeaway or takeout), which will bring our meals right to our doors. Of course, we have to pay for this convenience, so we expect the food to be good and hot!
