Hi @saipriyaM, 

When doing data modeling, ensure you understand business requirements, design for reusability, normalize data, and optimize for performance. Use appropriate property types, map relationships correctly, and maintain data security with validations. Avoid excessive nesting, plan for scalability, and document the model. Leverage data pages efficiently, be cautious with external data, and ensure queries and reports are optimized. Implement proper versioning and always consider data integrity and security.
