So, for example, if I had a layer filled with the color black-and then I selected Invert-it would make the contents white.

We can create a New Layer by tapping the Plus Sign in our Layers Menu. Note that your selected layer is highlighted in blue. Step 2īy default, in a New Document, you'll see two layers: Layer 1 and Background Color. To reveal your Layers, tap on the Layers Icon in the upper right-hand corner of your work area. The two layers could then be moved and manipulated independently-as opposed to if they were one, dependent work in a shared space. So, for example, I could draw something on one layer, and then create a new one for additional artwork. If you're unfamiliar, Procreate Layers work much like how they sound-they allow you to layer different pieces of content on top of each other, while maintaining a degree of independence. Getting Started With Procreate Layers Step 1 Hopefully, this question doesn’t bite you like it bit me and if it does, the interviewer steps in and comes through.1. There you have it: layers are logical tiers are physical.

Therefore, this is a 3-tier architecture. These 3 layers will probably be split and run separately on 3 physical servers. Let’s take the example of a modern application today that has an API, a React frontend and a database.

Therefore, if all your code is hosted on one server, that can be described as 1-tier. MVC can be classified as a 3-layer architecture because the code is logically split into 3: Model, View and Controller.Ī tier is the physical deployment of a layer e.g a server, a computer.

And just like every software developer who has a question, I turned to Stack Overflow.Ī layer is a logical organisation of code and can include the business layer, the data layer and the presentation layer. Luckily, they were a good interviewer and they went on to explain what it was.įast forward to this year and I decided to finally understand what exactly is the difference between a tier and a layer.

“MVC is not an example of 3-tier architecture”. The interviewer cut me short immediately. MVC is an example of 3-tier architecture”

“3-tier architecture is when the code is split into 3 groups: presentation layer, data layer and the business layer. “Can you tell me what is 3-tier architecture?”

The interview had been smooth so far until the interviewer asked about web application architectures. A while ago, I was doing a technical interview over video call.
