Transaction design is not a part of the database design process
Database design is a crucial step in developing a database system that meets the requirements of the users and the organization. It involves several stages to ensure that the database is efficient, reliable, and scalable.

Conceptual design
- Involves defining the high-level structure of the database without considering specific technical details.
- Focuses on identifying entities, attributes, and relationships between entities.
- Helps in understanding the data requirements and constraints of the system.

Logical design
- Translates the conceptual design into a more detailed representation using a data model such as an Entity-Relationship Diagram (ERD).
- Defines tables, columns, keys, and relationships based on the requirements captured in the conceptual design.
- Ensures data integrity, normalization, and performance optimization.

Physical design
- Involves implementing the logical design into a physical database schema on a specific database management system.
- Considers storage structures, indexing, partitioning, and other physical implementation details.
- Aims to optimize query performance, storage efficiency, and data retrieval speed.

Transaction design
- Transaction design is not a part of the database design process.
- It refers to designing the transaction management system that ensures data consistency and integrity during database operations.
- Involves defining transaction boundaries, isolation levels, concurrency control mechanisms, and error handling strategies.
- Although crucial for maintaining data consistency, transaction design is more closely related to database management and application development than database design.
