What is logical data model?..

Answer / Poonam Kushwaha

A Logical Data Model (LDM) is an abstract representation of a database, independent of any specific physical database management system. It defines the structure and relationships between entities, attributes, and relationships, providing a blueprint for designing databases or data warehouses. In Teradata, LDMs can be used to create star schemas and snowflake schemas.
