A Peer-to-Peer Lending Platform Data Model
There are many online portals which allow investors to lend money directly to individual borrowers – with no banks acting as intermediaries. What data model might underlie such a site? Online lending platforms bring borrowers and investors together and allow them to choose to whom they want to lend their money (in the case of investors) and who they want to borrow money from (in the case of borrowers). Some peer-to-peer lending sites also allow borrowers and investors to make their own deals in terms of lending rates (i.
A Subscription Business Data Model
In the previous two parts, we’ve presented the live database model for a subscription-based business and a data warehouse (DWH) we could use for reporting. While it’s obvious that they should work together, there was no connection between these two models. Today, we’ll take that next step and write the code to transfer data from the live database into our DWH. The Data Models Before we dive into the code, let’s remind ourselves of the two models we’ll work with.
A Subscription Business Data Model
Can you design an OLAP database model from an OLTP model? In this article, we’ll show you how! This is the second article of our data warehouse (DWH) series. You can find the first one here. The idea behind the series is to start with the OLTP (Online Transaction Processing) database model, present a possible solution for the reporting/OLAP (Online Analytical Processing) data model, and then finally consider the code we’ll use to perform the ETL process.
A Subscription Business Data Model
Welcome to a new series that shows you the practical side of the data warehouse (DWH)! In the first article, we’ll tackle a data model for a subscription business. In previous data warehouse articles (The Star Schema, The Snowflake Schema, Star Schema vs. Snowflake Schema) we focused more on the theory. In this series, we’ll show you how you could create a data warehouse for a real-life application, such as a database model.
A Marathon Training App Data Model
Do you dream of running a marathon? Let’s look at the data model for an app that could take you from lazy couch potato to marathoner. What do you need to run a marathon? You’ll need enthusiasm and determination. A good pair of running shoes. And lots of physical training! Let’s say you have an app that helps you go from novice runner to marathon finisher. What would the data model look like?
The Secrets of Dominoes, or A Domino Game Data Model
Board games like dominoes are still very popular. Let’s take a look at dominoes from a data modeling point of view. The game of dominoes has been around for hundreds of years, and it’s played all over the world. As you might expect, this means a lot of variations in play! In this article, we’re going to examine a data model that could support the most common variants – draw and block.
Earn Money with Unused Stuff: A Sharing Economy Data Model
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?
Tap and Park: A Parking App Data Model
Various apps promise to make your search for parking painless. Let’s examine this type of app using our data modeling glasses. What does the underlying model look like? In an earlier article, we explained how a parking lot is structured and how a data model can be designed to manage one. In this article, we are examining the data model for a parking app. You know these apps: they list nearby parking options, tell you the prices, and let you book or reserve a space or buy a parking pass.
A Children’s Party Data Model
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.
A Data Model for a Weather App
Lots of people use mobile weather apps to plan their day – or at least decide if they need to carry an umbrella! What sort of data model lies underneath these popular programs? We all want to know how nasty the weather is before we step outside. Windows, iOS, and Android apps give us accurate and reliable information about current weather conditions. This article explains a detailed data model that could be used for such apps.
A Data Model for Trading Stocks, Funds, and Cryptocurrencies
Trading cryptocurrencies, buying stocks, and the like is extremely popular these days – it’s perceived as easy profit. Prices are currently rising, but we can’t know when that will change. On the other hand, we know it will at some point. But we’re not here to make financial predictions. Instead, we’ll talk about a data model that can be used to support the trade of cryptocurrencies and financial instruments like stocks or fund shares.
Star Trek 3D Chess Data Model
If you’re a Star Trek fan, you likely know that Captain Kirk and Mr. Spock frequently play a variant of chess called Tri-Dimensional Chess, or 3D chess, a game that’s similar to standard chess but with notable differences. In this article, we’ll build a data model for a 3D chess application that allows players to compete against each other. Beam us up, Scotty! The Concept of 3D Chess While chess itself is already a complex game, combining boards and multiple sets of pieces can significantly increase the game’s complexity.
Delivering Christmas Presents: Santa’s Data Model
With the holidays quickly approaching, Santa needs some additional help to deliver presents to children around the world. Today, we’ll develop a data model that can help Santa and his elves work more efficiently. Background Santa’s job is extremely important, so he needs to do everything he can to ensure on-time success. Just remember all the problems Howard encountered in ‘Jingle All the Way’ when trying to find a single Turbo Man figure—we can’t let Santa slip up again, or his reputation will be ruined.
Constructing a Data Model for a Parking Lot Management System
Research shows that cars remain parked for 95% of their lifetime, suggesting that parking lot management systems should be smart, efficient, and robust. In this article, we’ll construct a data model for such a system. Introduction Before we begin constructing our data model, we should first understand how parking lots are structured and how they operate. Let’s take a brief look at these two key areas. How are parking lots structured?
Life Insurance Data Model
Life insurance is something we all hope we won’t need, but as we know, life is unpredictable. In this article, we’ll focus on formulating a data model that a life insurance company may use to store its information. Life Insurance as a Concept Before we start discussing the actual data model for a life insurance company, we’ll briefly remind ourselves of what insurance is and how it works so we have a better idea of what we’re working with.
Modeling an Open Marketplace for Education
Keeping up with the latest changes in technology is necessary if you want to get ahead in today’s competitive job market. In this article, we’ll build a data model for online portals that offer a more engaging platform for learning new skills, using Native Monks as our guide. Introduction In one of our recent articles, we built a working data model for an e-learning portal, and we explained how courses can be split into recorded/transcript lessons and made available to students.
A County Club Data Model
Sometimes you need a break and you don’t want to travel all that far to get one. Why not go to a local or county club? We look at a data model to help county clubs everywhere stay organized. Imagine that you’re in southeast England, somewhere in East Sussex or West Sussex or Kent. The grass is just the right length, the tea is the perfect temperature, and it’s raining a little.
Data Model Design: A Mobile App Marketplace for Local Services
Using a mobile app to hire builders, landscapers, and other skilled professionals makes taking care of property less of a hassle. In this article, we look at a data model to support such an app. Is it easy for you to hire a plumber, handyman, or electrician? Most people would say no! That’s why there are several apps and services that match service professionals with buyers. These apps are based on a simple, one-platform concept.
