Moving Beyond Spreadsheets
The course is part of this learning path
This course discusses some of the fundamental concepts of data management and looks at the differences between spreadsheets and databases for managing data. We'll look at some specific examples to understand when spreadsheets makes sense and when it makes sense to switch over to a database, which is sometimes a much better option for more complex datasets.
Specifically, this course aims to give students a practical hands-on introduction to database concepts. In addition, we'll gain an understanding of how to select the right database and we'll go through the basics of setting up an RDS instance on Amazon. This course includes a practical example of a company that is looking to choose a database, to give you an understanding of how databases work in the real world.

This course is designed for anyone who wants to improve their knowledge of databases and understand when it makes sense to use them as opposed to a spreadsheet.
To get the most out of this course, you should already have a basic understanding of simple data structures such as comma-separated values, as well as an understanding of cloud concepts in general.
Hopefully, now you've written down some of your use case and let's use this graphic to guide us through picking the right database from a practical level. The first component we need to understand is the structure of the data. Now, we've briefly touched on data models and if it's flat, but we need to just decide, is this something that's representable in tables? Multiple tables? Is it may be a set of key value pairs? Maybe it's a set of documents with an associated amount of massive unstructured free text?
It's important to think about this because this will help guide you to whether or not you want a relational database or maybe a NoSQL database because your data formats are inconsistent. In terms of this coffee bean subscription service that we're launching and running, we have a lot of information coming in that's coming from customers.
The information that we need, though, is pretty straightforward and pretty structural, even though it's maybe coming in from email, from phone, or from direct in-person support channels, very importantly, it ties to a sale or an order and a product and then a customer feedback score and comment. So we can structure it in table format. So for the point of this coffee bean shop, we're gonna go with a SQL database.
