Data Modeling
Data Modeling is like creating a blueprint for how information should be organized and stored in a company's systems. It's similar to how an architect makes plans before building a house. Data modelers take messy, complex information and turn it into clear, organized structures that make it easier for businesses to use their data effectively. Think of it as creating a filing system, but for digital information. This skill is essential in data analytics, business intelligence, and database management. When companies talk about data modeling, they might also call it database design or data architecture.
