The Database System Development Life Cycle (DBSDLC) outlines the stages involved in designing, building, and maintaining a database system. It begins with requirements analysis, where business needs are identified, followed by conceptual design, creating an abstract representation of the database. Next, logical design structures the database with entities, attributes, and relationships, followed by physical design, which implements the database on a specific platform. Finally, the system undergoes testing, deployment, and maintenance to ensure it meets user needs and adapts to changes over time. By Prakash/AP-AI&DS
