2. Attributes: Attributes are the properties or characteristics of entities. Each entity typically has multiple attributes that describe various aspects of the entity. For instance, attributes of a “Customer” entity might include “Name,” “Email Address,” and “Phone Number.”
3. Relationships: Relationships define the associations between entities. They describe how entities are connected or related to each other. Relationships can be one-to-one, one-to-many, or many-to-many. For example, a “Customer” entity may have a one-to-many relationship with an “Order” entity, indicating that a customer can place multiple orders.
4. Keys: Keys are attributes or combinations of attributes that uniquely identify each instance of an entity. A primary key is a key that uniquely identifies each record in a database table. For example, in a “Customer” table, the “CustomerID” attribute might serve as the primary key.
5. Normalization: Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves breaking down large tables into smaller, related tables and establishing relationships between them. Normalization helps prevent data anomalies and inconsistencies.
6. Denormalization: Denormalization is the opposite of normalization. It involves combining tables or duplicating data to improve performance in read-heavy scenarios. Denormalization can be used strategically to optimize query performance, especially in data warehousing and analytics environments.
7. Data Modeling Notations: There are various notations and techniques for representing data models, including Entity-Relationship Diagrams (ERDs), Unified Modeling Language (UML), and dimensional modeling for data warehouses.

Overall, data modeling plays a critical role in designing databases and data structures that accurately represent the underlying business requirements and facilitate efficient data storage, retrieval, and analysis. By creating well-designed data models, organizations can ensure that their data assets are effectively managed and utilized to support business objectives.
