Imagine you have a toy box with different types of toys in it, such as dolls, cars, and blocks. Each toy has its own specific use and is meant to do something different. Similarly, domain-specific multimodeling is when you have different "toy boxes" for different purposes, where each box has a specific set of tools for a specific task.
For example, let's say you are building a website. You need to use different tools and codes for designing the layout, creating the content, and managing the database. Instead of putting all these tools in one big "toy box", you can separate them into smaller "toy boxes" based on their specific tasks. This way, it becomes easier to manage the tools and work with them in a more focused manner.
Domain-specific multimodeling allows you to use different sets of tools for different domains, or areas of focus. It helps you organize and structure your work in a more efficient and effective way, much like the toy box example. By having a separate set of tools for each task or domain, you can work more quickly, accurately, and with greater precision.
