This video describes about the Data Dictionary that will be used to model a database design for the e-tail system.
Data dictionaries are essential for data governance, data management, and database administration. They promote consistency and understanding across an organization by providing a common language for data-related discussions. Additionally, data dictionaries can assist in data modeling, database design, data integration, and data analysis tasks. They are particularly valuable for large and complex databases where understanding the meaning and context of data elements can become challenging without proper documentation.
