ELI5: Explain Like I'm 5

Architecture description language

Imagine building a house. Before starting the construction, you need to make a plan, right? You need to know how many rooms will be in the house, where the kitchen and bathrooms will be, how big the living room will be, how many floors, and so on. But you can't just draw any kind of plan. It needs to be very specific and include every detail of the structure. This is similar to what an architecture description language (ADL) does.

ADL is like a plan, but for building software systems. Just like different kinds of houses, software systems can also come in all shapes and sizes. So, ADL helps developers to design, describe, and document software systems. These descriptions can tell us what the software will do, how it will work, and how it will interact with other parts of the system or with other systems.

ADL is often used for developing complex software systems, such as those used in air traffic control, medical equipment, and financial systems. These systems require careful planning and designing before they can be built, and ADL helps to make that process more manageable.

Think of it like a Lego set. Before you start building, you look at the instructions to see how to put the pieces together. Similarly, software developers use ADL to understand how different components of the system fit together, how they interact with each other, and what they're supposed to do. This helps to make the software more reliable, efficient, and effective.
