data modeling techniques

Data modeling techniques are methods used to organize and define how data is structured and related within a system. Think of it as creating a blueprint for data, helping ensure consistency and efficiency. Techniques like Entity-Relationship Diagrams (ERDs) visually map out data entities (like customers or products) and their relationships, while normalization reduces redundancy for better storage. These methods help teams design databases that are logical, scalable, and easy to manage, serving as a foundation for data-driven decision making and software development.
